An axle load calculation method for an articulated three-axle passenger car comprises the steps of: obtaining the mass and the mass center of each component of a front carriage and the horizontal distance between the position corresponding to the mass center and the supporting shaft of the front carriage; calculating the axle load of each supporting shaft of the front carriage by using a preset algorithm according to the mass of each component and the horizontal distance from the corresponding mass center position to the supporting shaft of the front carriage; obtaining the mass and the mass center of each component of the rear carriage and the horizontal distance between the corresponding mass center position and the rear carriage supporting shaft; according to the mass of each componentand the horizontal distance between the corresponding mass center position and the supporting shaft of the rear carriage, calculating the axle load of each supporting shaft of the rear carriage by utilizing a preset algorithm; and finally, obtaining the total axle load of each supporting shaft according to the axle load of each supporting shaft. According to the method, axle load distribution canbe checked without waiting for completion of actual sample vehicle development, design changes in the sample vehicle development process are reduced, and the product development period is shortened; and the scheme can be adjusted in time in the design process, and axle load distribution is optimized.

    一种铰接式三轴客车轴荷计算方法,包括步骤:获取前车厢各组成部分的质量以及质心,以及对应质心位置距离前车厢支撑轴的水平距离;根据各组成部分的质量以及对应质心位置距离前车厢支撑轴的水平距离,利用预设算法计算前车厢各支撑轴的轴荷;获取后车厢各组成部分的质量以及质心,以及对应质心位置距离后车厢支撑轴的水平距离;根据各组成部分的质量以及对应质心位置距离后车厢支撑轴的水平距离,利用预设算法计算后车厢各支撑轴的轴荷;最终根据各支撑轴的轴荷,获取各支撑轴的总轴荷。通过该方法不必等到实际样车开发完成后就可校核轴荷分配,减少样车开发过程中的设计变动,缩短产品开发周期;且可在设计过程中及时调整方案,优化轴荷分配。
