Mobile electric cars machine is a kind of equipment is not required or crane, artificial can promote, portable and mobile electric car automatic control of synchronous lifting function machine. Security problem of mobile car machine one of the three major overhaul equipment as electric locomotive depot for the railway has more and more aroused the attention of designers. Design and manufacture of mobile lifting machine, in addition to considering the mechanism can be simple, safe, convenient up electricity or diesel locomotive bogie, launch, should also pay attention to the strength and stability problems of its own. Analysis on the optimization design of the frame part stress according to the actual plant visits and mechanics, the design is focused on the stability of mobile car machine, improve the service life and reliability, the lowest of the repair costs, economy of long period of use the mobile frame machine frame is high, bearer mobile lifting machine, not only bear the motor, the base and the rack truck quality, but also bear a variety of forces and moments generated operation process. Therefore, its strength is not only related to the cars efforts, but also related to the safety of the vehicle.Keyword:Keyword: Frame Mobile electric cars machine DT015目录一、 概述1二、 总体设计与拖头说明计算5 2.1移动式架车机总体说明5 2.2 升降部分设计 9三、 机架计算12 3.1 移动式架车机机架的受力分析12 3.2 截面的选择15 3.3 强度和刚度验算16 3.4 稳定性验算18 3.5 梁高的确定19 3.6 腹板的厚度20 3.7 翼缘板的厚度203.8 整体强度和刚度验算213.9 总体稳定性验算223.10组合梁的局部稳定性233.11梁的拼接24四、 总结25参考文献27毕业实习报告28附录或后记30 河北建筑工程学院毕业设计计算书指导教师： 设计题目：移动式架车机DT015 机架结构优化设计设计人：设计项目计算与说明结果2.1移动式架车机总体说明2.2 升降部分设计 2.2.1移动式驾车机升降部分传动轴的设计与要求 2.2.2升降部分托头的设计要求2.2.3驾车机的托头的受力分析与计算 3.1 移动式架车机机架的受力分析 3.1.1驾车机机架结构简图（3-1 3-2）3.1.2移动式驾车机的结构特点3.1.3移动式驾车的工作原理3.2 梁的截面的选择 3.2.1净抗弯截面系数的选择
