| 摘 要： | 以轨道车辆为背景,依据转轴公式和平行移轴公式得到车体截面内任意倾角部件的惯性矩,进而获得截面的刚度及其灵敏度。在已知车体刚度分布的前提下,依据车体刚度及其灵敏度,通过调整刚度薄弱位置相关部件的截面尺寸,可达到提高车体刚度的目的。

| Abstract: | With the railway vehicles as the background,on the basis of the rotary axle formula and the parallelly moving axle formula,the inertia moment of the part with an arbitrary incidence in the carbody section is obtained,and the stiffness and its sensibility of the section are obtained.With the prerequisite of knowing the distribution of carbody stiffness,on the basis of the stiffness and its sensibility of the carbody,through adjustment of the section dimensions of the relevant parts at positions of weak stiff... |
