整体承载是在高速动力车车体结构上采用的一种新的机车车体承载方式。沿车体纵、横及水平方向组成一定数量的封闭框架 ,并由网格梁配合承载蒙皮实现了这一承载方式。通过建立良好的车体结构计算仿真模型 ,在对采用新型结构的高速动力车车体结构进行大量分析计算的基础上 ,在保障安全、保证刚度、强度的前提下 ,实现了车体结构的轻型化。车体结构静强度试验验征了结构的合理性和计算的有效性
The overall bearing is a new type of locomotive body bearing method adopted on the body structure of high-speed electric vehicle. A certain number of closed frames are formed along the longitudinal, horizontal and horizontal directions of the vehicle body, and the bearing manner is achieved by the grid beam cooperating with the bearing skin. Through the establishment of a good simulation calculation model of vehicle body structure, based on a large amount of analysis and calculation of the body structure of a high-speed power vehicle adopting a new structure, under the precondition of ensuring safety, ensuring rigidity and strength, The The static strength test of the vehicle body structure verifies the rationality of the structure and the validity of the calculation
