| 摘 要： | 以铁道部四方车辆研究所实测的206型转向架的垂直、水平两个方向的八级载荷谱为研究对象,结合损伤理论,用概率论的方法求得构架在垂直和水平随机载荷联合作用下的合成谱。并用货车侧架在单级垂直和水平脉动载荷的实验结果对合成方法进行了部分验证,其结果是令人满意的。

| Abstract: | The vertical and level 8-grade load spectrums of type 206 truck frame, measured by Sifang Rolling Strock Research Institute are taken as the object of study in this paper. The synthetic load spectrum of truck frame acted by vertical and level random loads is obtained using the probability method and damage theory. The results of the experiment of freight car's side frame under the single-grade vertical and level vibrating loads are used to prove the synthesis; and satisfactory results are achieved. |
