Abstract

In order to reduce resonance of all-in-one machine of combine harvester and baler in normal operation, using 3D software of the compression device for parametric modeling, finite element simulation of compression device by ANSYS-Workbench software, calculating the first fourth order modal frequency and formation of compression device, and using modal analysis and modal test to the compression device. Test results show that the finite element simulation and modal test results basically are consistent. By analyzing the external excitation frequency, the first modal frequency of the compression device is similar to the excitation frequency of the vibration sieve, and the form of motion is a reciprocating motion, and the resonance phenomenon is easy to occur. The second modal frequency of the compression device is in the range of excitation frequency of Threshing cylinder, and the resonance phenomenon is obvious when the whole machine is in normal work.
