摘要
运用CATIA软件对高压气体车架进行三维实体参数化建模,并将模型导入ANSYS软件中建立车架结构有限元的实体单元模型,对车架在弯曲和扭转两种工况下的应力特性进行深入研究,对车架进行性能分析评价;利用APDL语言建立车架纵梁的优化模型,运用ANSYS Design opt模块对现有车架纵梁结构尺寸进行优化设计。根据该特种车的实际使用工况和应力特性的分析结果提出专用车架设计方案,为设计新型长管半挂车提供参考依据。
The three-dimensional entity parametric model for long-tube semi-trailer frame was built by using CATIA software. Then the model was incorperated into ANSYS software to establish the frame's solid element model and a intensive research was made on frame's stress characteristics in bending and twisting. The optimized model of frame longeron was established by Using APDL and its dimensions was optimized using ANSYS Design opt module. Finally, the special frame design scheme was put forward according to the actual operation condition of semi-trailer and stress characteristics analysis results which can provide reference value for new semi-trailer design.
