在铁道车辆弹簧悬挂装置中广泛采用圆柱形螺旋弹簧,以保证簧上部分有足够的空间位移。例如,客车转向架轴箱悬挂中垂直安装圆柱形螺旋弹簧,构架可相对轮对移动。结构元件在水平平面内移动将导致弹簧轴线歪曲并在其端部出现由固接条件引起的力矩。弹簧支承面内的力矩影响到与之相连接零件的强度和弹簧本身在水平平面内的变形。在《交通部关于轨距1524毫米的新造和现代化铁道车辆(非自动车辆)的机械部分强度计算和设计规范》手册中规定的用于确
Cylindrical coil springs are widely used in railway vehicle spring suspension devices to ensure sufficient space displacement of the sprung portion. For example, a cylindrical helical spring is vertically mounted in the suspension of a passenger car bogie, and the frame can move relative to the wheelset. The displacement of the structural element in a horizontal plane causes the spring axis to be distorted and at its ends a moment due to the fastening conditions occurs. The torque in the spring bearing surface affects the strength of the part to which it is connected and the deformation of the spring itself in the horizontal plane. In the “Ministry of Communications 1524 mm gauge on the new and modern railway vehicles (non-automatic vehicles) strength calculation and design specifications,” the provisions of the manual for the
