Integrating Static and Dynamic Load Analysis for Optimized Bottom Frame Design in Industrial Machine Applications

The objective of this study was to comparatively analyze the strength and stress distribution of three bottom frame design variations of the Bandrole machine. This analysis was conducted using both static and dynamic load analyses, which were based on Computer-Aided Engineering (CAE). The three variations included the original manufacturer's bottom frame (Design 1), a modified frame with an additional footplate (Design 2), and a modified frame with reinforced side walls (Design 3). The dynamic simulation results demonstrated that Design 2 yielded the maximum force of 6321.06 N, accompanied by a 16.146% increase in load. Concurrently, the static analysis revealed that Design 2 manifested the lowest Von Mises stress (13.76 MPa) and minimal deformation (0.0154 mm), thereby confirming its status as the optimal design. Furthermore, testing under different rotational speeds (400–600 rpm) confirmed the stability of Design 2, with only minor changes in stress and deformation observed. The findings of this study yielded recommendations for enhancing the reliability of machine design, which could serve as a benchmark for the future development of analogous machine structures.
