用基底矢量法对瑞典Ｘ型摆式列车的摆式机构进行了动态静力分析，整个过程没有近似处理，全部未知力都表示为已知量的显函数。计算结果精确，耗时减少。该方法和结果可以用于车体的运动解析、动力控制以及材料、结构的研究
The dynamical static analysis of swivel mechanism of Swedish X-type tilting train is carried out by the method of substrate vector. The whole process is not treated in an approximate way and all the unknown forces are expressed as the explicit functions of the known quantities. The calculation results are accurate and time-consuming. The method and the results can be used for vehicle body motion analysis, power control and materials, structural studies
