摘要
为保证300 km/h动力集中型动车组轴盘制动装置试验工装满足试验要求,文章结合轴盘制动装置的结构特点和实际工况,设计轴盘制动装置试验工装,并利用ANSYS Workbench仿真软件对工装进行刚度、强度分析。利用在紧急制动工况下对工装的应力、变形及分布规律的分析结果对工装结构进行优化设计,优化后的工装性能结构更加合理,可提高试验的可靠性。
In order to ensure the test fixture of axle-disc brake device of the 300 km/h power centralized EMU to meet the test requirements, the paper designs the test fixture of axle-disc brake device in combination with the structural characteristics and the actual working conditions of the axle-disc brake device. ANSYS Workbench simulation software is used to analyze the stiffness and strength of the fixture. According to the analysis results of the stress, deformation and distribution of the fixture under the emergency braking condition, the optimized design of the fixture structure is carried out. The performance and structure of the optimized fixture is more reasonable,and the reliability of the test can be improved.
