Finite Element Analysis of Self-propelled Wolfberry Picker Frame
In order to develop a frame with sufficiently high strength and stiffness to meet the operational requirements of the picking machine,this study uses the simulation software Ansys Workbench,quasi-static structural analysis and modal analysis of the frame of the wolfberry picking machine,to determine the optimal vibration frequency of the picking machine,to avoid resonance phenomenon of the picking machine.The results show that the picker has the lowest intrinsic frequency in the first-order modal state,and its lowest intrinsic frequency is 36.582 Hz.The vibra-tion frequency interval of the picker is 10.094～14.498 Hz,which is lower than the lowest intrinsic frequency of the frame,and no resonance phenomenon occurs during the operation of the picker.This study can provide a reference for the structure optimization of self-propelled wolfberry picker.
