摘要

针对某公司生产的18方混凝土搅拌车副梁存在失效问题,在建立副梁力学模型可行性的基础上采用有限元分析法对副梁进行了静力学分析。建立副梁有限元模型,确定搅拌车工作过程中不同状况,通过分析副梁静力学特性获得在不同工况条件下应力应变分布情况,分析结果表明在3种工况条件下副梁的最大应力区域存在失效现象。以降低应力和重量为目标,采用拓扑优化算法对副梁结构进行了优化,分析了优化后副梁的轻量化结果和静力学特性,结果表明:优化后副梁的重量和应力都较前有所降低,最大应力区域的失效问题得到解决,优化后副梁能够满足企业设计要求。

Abstract

In view of the 18 m~3 concrete mixing truck subframe has failure problem,based on the feasibility ofestablishing the subframe mechanical model,using the finite element to analyze the subframe static. Established the subframe finite element model,determined the different conditions in the working process of the mixer truck,it obtained the distribution of stressstrainunder different working condition through analysis the subframe static characteristic,the result of analysis indicated that there was failure phenomenon in maximum stress area of subframe under three working condition. Aimed at reducing stress and weight,it designed topological Optimization algorithm for optimizing the subframe structure,analyzed the light weighting result and stress statics characteristic of optimized subframe,the result indicated that the stress and weight of the optimized subframe lower than before,the failure problem of maximum stress areahas been solved,the optimized subframe can satisfy the enterprise design requirements.
