摘要
针对目前汽车衡秤体结构材料利用率低、质量大的问题,将结构优化设计的方法引入到秤体结构设计中。以U型梁和秤台的几何尺寸为设计变量,秤体的最大挠度为约束条件,秤体整体质量为目标函数,利用参数化APDL语言建立了秤体结构的有限元优化模型,对秤体结构进行了优化分析,从而确定了U型梁和秤台的几何尺寸。研究结果表明,在满足秤体刚度和强度设计要求的前提下,秤体结构优化后的质量比原来的降低了6.7%,实现了降低秤体结构质量的目的,提高了材料利用率。
Aiming at the problem that low material utilization and large mass of truck scale,the method of structural optimization design can be introduced in the process of design of truck scale body.The finite element optimization model was built,which defined the geometry of U beam and weighing platform as design variables,maximum deflection as constraint condition and weight as the objective function,by APDL language.The geometry was determined by analysis.The results show that,on the premise of stiffness and strength,the quality of this structure is reduced by 6.7％.The purpose of lowering the weight is achieved and material utilization is improved.
