摘要:
为了得到简单可靠的清扫车举升油缸支架结构，建立了以体积分数( Volume Fraction)为约束条件、以结构加权应变能( Weighted Compliance)为目标函数的变密度法( Variable Density Method)拓扑优化数学模型，利用线性近似的方法，分析了采用复合式垃圾箱的道路清扫车在倾倒垃圾过程中油缸支架的受力状况，确定了举升起始工况和检修工况作为设计油缸支架的主要受力工况。采用变密度法对油缸支架进行了拓扑优化设计。在考虑制造工艺可靠性的前提下，以拓扑优化结果为基础建立了清扫车举升油缸支架的三维模型，并进行了线性静态分析。结果表明，基于变密度法设计的清扫车举升油缸支架结构简单，占用空间小，最大应力与最大应变均处于合理范围，满足使用要求。
Abstract:
In order to design a simple and reliable lifting hydro-cylinder bracket structure, the topology optimi-zation mathematical model based on the Variable Density Method was established by the volume fraction as constraint conditions and the weighted compliance as objective function. By means of linear approximation method, analyzed the force condition of the lifting hydro-cylinder bracket of a road sweeper with composite trash bin in the dumping process and determined lifting starting condition and maintenance condition as the main force conditions for the design of the lifting hydro-cylinder bracket. The topology optimization design of the lifting hydro-cylinder bracket was carried out by using the Variable Density Method. Considering the relia-bility of manufacturing process, a three dimensional model of the lifting hydro-cylinder bracket was established based on the topology optimization results, and the linear static analysis of the model was carried out. The final results showed that the lifting hydro-cylinder bracket designed by the variable density method had the advanta-ges of simple structure, small occupied space, the largest stress and maximum strain in reasonable range and met the requirements of the application.
