摘要: 为实现履带喷雾车车架结构的轻量化,利用Pro/E软件建立了喷雾车车架的三维模型,并导入到ANSYS Workbench软件中,再对喷雾车车架在空载和满载两种工况下进行有限元分析,获得了车架结构的等效应力、总体变形及安全系数云图,找到了车架结构的薄弱和冗余部位,并进行了车架设计参数敏感度分析,在此基础上提出了履带喷雾车车架的优化设计方案。通过对喷雾车车架的优化设计,其总重量由优化前的457kg降为371kg,降幅达 18.82%,结果验证了优化方案的合理性。研究结果对履带喷雾车的车架设计改进具有一定的技术参考价值。

Abstract: To achieve lightweight design for frame of a tracked spraying vehicle,the 3D model of the vehicle frame was built by using Pro/E,and imported into ANSYS Workbench software,then,was analyzed using finite element method for the frame of the tracked spraying vehicle under two working conditions with no-load and full load respectively,the cloud chart of the equivalent stress,total deformation and safety factor of the frame were obtained,the weak and the redundant position of the frame were also found,parameter sensitivity analysis was performed.The optimization design scheme of the frame of the tracked spraying vehicle is put forward on the basis of the above.The total weight of the frame is reduced from 457kg to 371kg,decreased by 18.82% after optimization design of the frame,which verifies the rationality of the optimization design scheme.The research results have some technical reference for design improvement for the frame of the tracked spraying vehicle.

Key words: tracked spraying vehicle, frame, finite element method, ANSYS, optimization
