本文介绍了3种由UVZ和VNIKTI工厂生产的轴重为25 t货车新型转向架动力试验的结果分析。对在直线和过渡曲线区段运行的空车转向架的蛇行问题给予了特别的注意。文章指出,UVZ工厂生产的转向架在运行速度大于100km/h时易发生激烈的蛇行现象,而与其他试验转向架相比,VNIKTI转向架具有最大的侧架力,这是由于转向架相对于车体有更大的转动阻止力矩的缘故。 This article presents the results of three dynamic tests of a new bogie truck with a shaft weight of 25 ton produced by the UVZ and VNIKTI plants. Special attention was paid to the hunting of empty bogies operating in the straight and transitional curve sections. The article states that the bogies produced at the UVZ plant are subject to intense meandering at speeds greater than 100 km / h, whereas the VNIKTI bogie has the largest amount of side frame force compared to other test bogies due to the bogie relative to The body has a larger rotation to prevent the sake of the moment.
