机車車辆的設計者必須使所設計的車辆具有良好的振动特性和运行品质。为此,必須弄清影响車辆振动的許多因素,設法将其减小到最小程度。在此文中,提出了設計轉向架所必需的基本数据;并在理論上解决了当車体被认为是剛体或彈性体时車体与轉向架的垂直振动。車体为剛体时的运动方程及其解 The designer of a rolling stock must make the designed vehicle have good vibration characteristics and running qualities. To do this, many factors that affect the vehicle’s vibrations must be identified and managed to be minimized. In this paper, the basic data necessary for the design of a bogie are presented and the vertical vibration of the body and the bogie is theoretically solved when the body is considered to be a rigid body or an elastomer. The equation of motion and its solution when the body is rigid body
