基于ANSYS Workbench的水稻插秧机机架结构设计与优化
Design and optimization of rice transplanter frame structure based on ANSYS Workbench
摘要
Abstract
The resonance of the rice transplanter can lead to the failure of the frame,which plays a critical role in supporting and fixing the machine,posing significant risks to both the normal operation of the equipment and personnel safety.To determine whether the frame of the rice transplanter would undergo resonance leading to structural failure,the static and modal analysis methods in ANSYS finite element analysis were used to calculate the stress and natural frequencies borne by the rice transplanter.Additionally,the operating frequency was calculated based on its own structural data to judge whether deformation failure would occur.The weak positions of the frame were analyzed,and an optimization scheme was proposed based on orthogonal experiments.For the optimized frame structure of the rice transplanter,under normal operating conditions,the maximum equivalent stress was reduced by 11.09 MPa,the maximum total deformation was decreased by 5.28 mm,the maximum mass was reduced by 5.6 kg,and the first-order natural frequency of the frame was increased by 10.17 Hz.Compared with that before optimization,the natural frequencies of the first six orders were increased to 13.49～50.70 Hz,which were higher than the safe area when resonance occurs.This provides a reference for further solving the vibration problem of the frame and improving the structure.关键词
