2CZ-21型甘蔗种植机机架的力学分析与优化

Mechanical Analysis and Optimum of Vehicle Frame of 2CZ-21 Sugar Cane Planter

简述了基于3D实体单元的2CZ-21型甘蔗种植机机架设计有限元法。分析了甘蔗种植机机架在弯曲和扭转组合工况下的应力和应变分布。讨论了机架在危险工况下的强度和刚度问题,提出了修改意见并对原有结构进行了优化。对改进设计后机架结构进行了强度和刚度分析,并确立了合理的轻量化方案。

The finite element method of design of the vehicle frame of sugar cane planter based on 3D solid element is introduced. The stress and strain of the vehicle frame when bearing bending loads and bending-torsion loads are analyzed. The frame strength and stiffness under over loading condition are discussed and the suggestions for design improvement are presented and primal frame have been optimized, the strength and stiffness of new frame structures are examined and the reasonable lightweight design is achieved.
