摘要: 通过建立垃圾堆曲面函数,给出自重、惯性、压缩、挤入和推出等基本工况下压缩垃圾载荷作用机理的变参数数学描述以及各种实际组合工况下压缩垃圾载荷的数学表达式。利用ANSYS软件对压缩垃圾车进行结构有限元分析,调校载荷数学表达中的可变参数,保证分析计算与试验测试结果一致,采用导重法对压缩垃圾车结构的外形与构件尺寸进行优化设计,在结构最大应力从504 MPa下降到176 MPa的同时,结构质量减少29.3 %。

Abstract: On the basis of supposes and test, load mathematical expressions of compressed rubbish to rubbish vehicle structure is given, so that the validity of finite element analysis is ensured. Using guide-weight method, on basis of finite element analysis, structural optimization of the compressed rubbish vehicle is successfully actualized. Through the structural optimization, with the same rubbish loadage, the structural weight of the compressed rubbish vehicle is lightened 29.3%, and the maximal stress decreased from 504 MPa to 176 MPa.
