Submitted: 19/10/2025 Revised: 07/12/2025 Accepted: 14/12/2025 Abstract The development of an Internet of Things (IoT)-based textile machine monitoring system requires a reliable and mechanically safe support structure.
A key issue in current practice is the design of control and monitoring frameworks that rely solely on prior models, without adequate testing and validation.
This study aims to evaluate the structural strength of the textile machine monitoring system support frame using the Finite Element Method (FEM).
The 3D frame model was designed using CAD software and analysed numerically via static simulation with a loading scenario of 100Ae150 N applied to the upper part of the structure.
The material used is mild steel with mechanical characteristics commonly used in industrial applications.
The analysis includes evaluation of Von Mises stress, displacement, and safety factor.
The simulation results show a maximum stress of 0.
5582 MPa, a maximum displacement of 0.
001842 mm, and a safety factor exceeding 12.
These values indicate that the designed structure has excellent resistance to static loads and is safe for use in industrial environments.
This study provides a strong foundation for developing a reliable and sustainable support structure for textile machine monitoring Keywords: Finite Element Method.

structural simulation Introduction The textile industry is a manufacturing sector highly dependent on the continuous operation and efficiency of machines .
To maintain performance and prevent premature damage.
Internet of Things (IoT)- based machine monitoring systems are increasingly being implemented across various production lines .
Ae.
This system enables real-time monitoring of machine conditions, thereby increasing productivity and reducing maintenance costs .
However, implementing such a monitoring system does not depend solely on electronic devices and communication networks.
it also requires a supporting structure capable of safely and stably bearing the device's load over a long period of time.
In practice, the supporting structures of monitoring systems are often designed conventionally without considering adequate mechanical evaluation .
This can lead to deformation, structural failure, or endanger operators and disrupt production processes.
Therefore, an engineering-based approach is required to assess the structural design's strength and stability .
One effective method for evaluating structural strength is the Finite Element Method (FEM) .
This method simulates actual loading conditions on a structure, enabling detailed analysis of parameters such as stress, displacement, and safety factor.

However, few studies specifically evaluate the supporting structure of textile machine monitoring systems, especially those that address space limitations in factories, the use of lightweight materials, and relatively small but unevenly distributed electronic loads.
Based on this background, this study aims to conduct a structural evaluation of the supporting frame of a textile machine monitoring system using the Finite Element Method.
The primary focus is on the analysis of Von Mises stress and displacement under static loads, and on the calculation of safety factors to assess the structure's feasibility in the operational environment of the textile industry.
This study is expected to fill a gap in previous research by providing a systematic, quantitative approach to designing a lightweight support structure that remains safe and sturdy to support the IoT-based monitoring system .
Method This study uses a numerical simulation approach based on the Finite Element Method (FEM) to evaluate the structural strength of the supporting frame of a textile machine monitoring system.
The process is carried out through four main stages, namely: .
frame model design, .
material selection, .
determination of loading and boundary conditions, and .
implementation of simulations and analysis of the results.
Frame model design A 3D model of the support frame was designed in Autodesk Inventor, with dimensions and configurations adjusted to accommodate electronic devices, including a mini PC, a monitor, a vibration sensor, and a microcontroller module.
The design took into account ergonomic aspects and installation requirements in a textile industry environment.
The structural dimensions refer to space efficiency and stability of equipment placement.
Material Selection: The simulation uses mild steel because it has suitable mechanical properties for lightweight structural applications.
The mechanical properties of the material used in the simulation are:
Modulus of Elasticity (Young's Modulu.
: 200 GPa, .
Poisson's Ratio: 0.
3, .
Yield Strength: A250 MPa.
Material selection considers strength, availability, cost, and ease of fabrication.
Loading and Boundary Condition Determination: Loading scenarios are designed to represent the actual loads the structure will receive during use.
A load of 100Ae150 N is applied to the top of the frame, representing the cumulative weight of the installed electronic devices.
The frame legs are given fixed boundary conditions to simulate the structure being rigidly attached to the floor, with no translational or rotational FEM Simulation and Result Analysis: The simulation was conducted in Autodesk Inventor using the Stress Analysis module and the FEM approach.
The main objective of this simulation was to obtain three main mechanical parameters, namely: .
Von Mises Stress, to determine the distribution and maximum stress value that occurs and compare it with the yield strength of the material.
Displacement, to see the extent of the structure's displacement due to the applied workload.
Safety Factor, to assess the safety margin of the structure against material failure.
All simulation results are analysed qualitatively and quantitatively to determine the structural feasibility of the proposed design.
Feasibility validation is based on mechanical engineering standards and material strength limitations.
Results and Discussion Support frame design Figure 1 shows the initial design of a support frame structure for a textile machine monitoring system developed using parametric Computer-Aided Design (CAD) software.
This frame is designed to support the system's main components, including sensor mounts, a mini PC platform, and modularly interconnected vertical and horizontal support elements.
The overall dimensions of the structure are 1000 mm in height, 300 mm in width, and 225 mm in depth, optimising space efficiency around the textile machine without disrupting production operations.

The parametric-based approach allows flexibility in design modifications, such as resizing or adding components as system development requires.
Furthermore, the structure is designed to ensure ease of installation and maintenance access, thus supporting the ongoing implementation of the monitoring system.

Von Mises Stress analysis results Figure 2 shows the results of the Von Mises Stress simulation of the supporting frame structure for the textile machine monitoring system, expressed in MPa (Megapascal.
The simulation was carried out by applying a static load of 100Ae150 N at the top of the structure to represent the actual load from the sensor components and the mini PC.

Structural Safety Evaluation: The maximum stress .

is still far below the yield strength limit of mild steel material (A250 MP.
, so the structure is considered safe from the risk of plastic deformation or material failure.
No critical stress concentrations were detected that could potentially cause cracking or fatigue under normal operational conditions.
Design Implications:
The simulation results validate that the current frame design is capable of withstanding static loads without the need for additional optimisation.
The upper connection area can be maintained without further reinforcement, but it is recommended to ensure the quality of the welding or mechanical fastening during production.
Visualisation through Finite Element Analysis (FEA) simulation strengthens the argument that the structure meets the reliability and safety factor criteria for textile industry monitoring system applications.

This value practically does not affect the monitoring system's Structural Safety Aspect: Theoretical calculations of the safety factor show an extremely high value (SF = 447.
The simulation results provide a minimum SF >12, far exceeding the industry standard for static applications (SFOu.
This condition indicates an overdesigned structure and has the potential for material optimisation.
This finding is in line with research on the nyamplung bean peeling machine, which used a similar methodology .
The main similarity lies in the effectiveness of the combined analysis of von Mises stress, displacement, and safety factor.
Although the current design meets safety requirements, several aspects need to be considered for further development, including material optimisation through component dimension reduction, the use of alternative materials such as aluminium, and the application of topology optimisation.
Conclusion This study evaluates the structural strength of the supporting frame of a textile machine monitoring system using the Finite Element Method (FEM).
The simulation and analysis results show that the parametric frame design successfully accommodates monitoring devices such as sensors, mini PCs, and monitors, with good space efficiency and stability.
Von Mises stress simulations yielded a maximum value of only 0.
5582 MPa, well below the yield limit of mild steel (A250 MP.
, indicating the structure is safe under the applied loads.
In addition, the minimum maximum displacement .
001842 m.
indicates high stiffness and minimal deformation during regular operation, while a safety factor above 12 enhances the structure's resistance to failure.
Thus, this frame is considered to meet the safety and strength requirements for application in a textile machine monitoring system.
However, further validation through experimental tests and dynamic analysis is needed to ensure its performance under real-world conditions.
