摘要：

In view of the problem that the inertia force was large and the vibration was difficult to solve，the model optimization design method was studied on the compression mechanism. With the development of intelligent agricultural machinery，big square baler density of bale need controlled based on the compression force，but there was no research on the compression force time domain waveform of big square baler in China. In order to design a big square baler and test the compression force of the bale density，the minimum average acceleration of sliders in a cycle was taken as the optimal design target，the transmission angle，velocity uneven coefficient and motion non-interference was taken as the constraints. The model shows that the crank length has a greater impact on the inertial force of the crank slider mechanism，and the longer the crank，the greater the inertial force. Based on the above parameters，YTO 9YFA-220 baler was designed and the compression force was tested. The results showed that the bale density was up to 230 kg/m3. The maximum compression force was 410 kN. The compression force appears shorter times in the whole period，about a quarter of the full cycle. The compression mechanism studied is of important engineering application value for the research and development of big baler. © 2024 Editorial Board of Jilin University. All rights reserved.
