Influence of partial load on riding quality of vehicle

A mathematic model of partial load vehicle was set up. As an example of a high-speed vehicle running on tangent track with Germany low-disturbing spectrum at 300 km・h^-1, the influences of all kinds of partial loads on the riding quality of vehicle were analyzed and compared by simulation. Analysis result shows that with the increase of partial load, the riding quality of vehicle is getting worse, longitudinal partial load has larger influence on the riding quality between the foreside and backside of vehicle, and lateral partial load has less influence on them. So in order to improve the riding quality of vehicle, partial load must be minished by all means, especially, longitudinal partial load must be strictly controlled. 5 figs, 10 refs.
