摘　　要：压裂车副车架是连接车辆底盘和安装设备的重要部件,承受压、扭及弯曲等载荷,需要足够的刚度和强度。在分析拓扑优化方法的基础上,利用变密度法对2500型压裂车副车架进行拓扑优化分析,得到副车架横梁的形式和布置位置,改进了副车架的设计方案。2种设计方案的强度对比分析结果表明:在横梁数量减少的情况下,副车架的承载能力提高了10.1%。Subframe of 2 500 fracturing truck is an important component, which connects chassis and the vehicle equipment. Because of bearing tension, torsion and bending loads, the enough ri- gidity and intensity are necessary for chassis design. After analysis the topology optimization method,the variable density method is employed to analyze the property of the subframe and thelayout and the location of the subframe is determined. Design of the subframe is improved. The result of the design presented in this paper shows that the carrying capacity of subframe is improved 10.1 % with the number of crossmember decreasing.
