Design and Analysis of 4LZ-8 Wheat Harvester Head

Abstract

In this paper, the parameter design of the header of the 4LZ-8 wheat harvester is established, and the three-dimensional model of the header is established. The header frame is selected as the main analysis object. The force analysis and static analysis of the header frame are carried out to detect whether it meets the stiffness requirements. In order to reduce the loss caused by vibration during harvesting, the pre-stressed modal analysis is performed on the designed header on the basis of statics to obtain the natural frequency and main vibration mode of the header frame, and then the vibration frequency is analyzed. The results show that the probability of resonance of other parts of the header with the header frame is relatively low, which meets the requirements for use.
