基于ABAQUS的水稻整株秸秆还田机刀轴应力仿真

Straw returning machine is the mostly tool for straw mechanical returning，and the cutter shaft is the key part which bear torque and vibration. Text study on the whole rice straw returning machine (1ZT-210) that developed by self，use the finite element software (ABAQUS) to Establish the static and transient force simulation，get the result that the vulnerable area at the middle of cutter shaft；and sure response time and response when generate the most displacement response，make sure the most bending stress of the girder，and get the stress which generate in the middle of the cutter shaft when different bent blades working by modality expansion. The research offer theoretical basis for improve design of cutter shaft.
