结合不锈钢车辆的特点,综合考虑车辆限界、重量分配、设备安装和维护空间等因素,研究出一个合理的底架设备布置方案,并对螺栓选型进行了分析。经试验和上线运营验证,设备布置满足限界、轴重和轮重偏差及安装维护要求。 Combined with the characteristics of stainless steel vehicles, considering vehicle clearance, weight distribution, equipment installation and maintenance space and other factors, a reasonable layout of the chassis equipment was studied, and the bolt selection was analyzed. After testing and on-line operation verification, equipment layout to meet the boundaries, axle load and wheel deviation and installation and maintenance requirements.
