| 1. | On the basis of detailed comparison and analysis , the paper proposed ways of using the k2 bogie and hdsa light - duty solid wheel , getting through the partition wall , canceling the longitudinal sill of the roof and decreasing the thickness of the board where the value of stress is low , using high intensity steel , increasing section dimensions of center sill and side sill , to improve the whole carrying capacity 本文在比较分析的基础上,提出了装转k2转向架,采用hdsa轻型碾钢轮,打通隔墙,取消车顶纵向梁,在应力小的部位减薄壁厚的减重对策;采用高强度耐候钢,加大中梁、侧梁的截面尺寸等措施,提高车辆的承载能力。 |
