Do research on the stress and deformation state in the condition of bending, braking, turning and reversing, and then make a program that improves the structure of the frame.
分析在弯曲工况、制动工况、转弯工况和扭转工况下的应力与变形状态，对应力集中位置结构提出改进方案。
When you first learn to drive it's 1000 activities like steering, shifting, checking mirrors, braking - but with practice you turned it into autopilot and it's no stress at all.
当你第一次学驾驶时要做1000种动作，比如握方向盘，转弯，看后视镜，踩刹车~——但随着练习，你把它变成了“自动驾驶”，你根本没有什么压力了。
The temperature and stress field of wagon wheel under the condition of long ramp way cycle braking in Daqin line have been simulated by using FEM and axial symmetry model.
采用轴对称模型和有限元方法，模拟了大秦线长大坡道循环制动条件下货车车轮温度和应力场，结果表明车轮高应力区出现在辐板上，现行制动条件下车轮强度满足使用要求。
