混凝土搅拌半挂运输车前支撑开裂分析及优化

摘 要：某型搅拌半挂车在行驶23000km时，车架前支撑发现多处开裂的现象。使用UG软件建立车架前支撑三维模型，通过仿真分析确定原结构的应力分布及应力最大值区域。通过结构优化创建多种车架前支撑结构，通过静止、加速、制动三个工况下的有限元分析对比，寻找最优方案并验证其可行性。

Cracking Analysis and Optimization of Front Support of Concrete Mixing Semi-trailer Truck

Chen Gang，Liang Peng，Wu Hongru

Abstract：Several cracks were found in the front support of the frame of a type of mixing semi-trailer when driving 23000 km. The three-dimensional model of frame front support is established by UG software， and the stress distribution and maximum stress area of the original structure are determined through simulation analysis. Through structural optimization， a variety of frame front support structures are created. Through finite element analysis and comparison under static， acceleration and braking conditions， the optimal scheme is found and its feasibility is verified.

Key words：a semi-trailer truck for concrete mixing， frame， cracking of front support of a frame， structure optimizatoon
