摘　　要：分析了交叉杆结构的副构架式径向转向架的导向机理和性能特点,重点研究了交叉杆结构参数对车辆动力性能的影响。建立了交叉杆结构的副构架式径向转向架车辆的动力学仿真模型,计算比较了结构尺寸不同的交叉杆结构转向架间稳定性与曲线通过性能的区别。给出了一个能使车辆动力学性能最好的交叉杆结构尺寸的优化取值区间。This article analyzes the steering principal and characters of the cross-braced radial bogie, concentrates on the structural parameters of the cross-braces which influ- ence the dynamic performance of the bogie, and sets up nonlinear dynamic simulation models of self-steering bogie, radial bogie and cross-braced bogie. The article also compares the dynamic behaviors of different configurations of radial bogies, finds out the main influential factors of the curving passing performance and stability of bogies, provides a size range of the cross-braces in which the radial bogie will have better dynamic performance.
