摘要

提出了一种2a-2a型底架竖向振动的计算方案。导出了一个由六个二阶微分方程组成的系统，该系统描述了垂直纵向平面上的振荡。利用Simulink应用程序在MathLab程序中建立了机车断面模型。确定了机车运动纵向垂直区域内机体振荡随时间的函数和机车运动纵向垂直区域内机体倾斜随时间的函数。

Simulation of Oscillations of a Type 2a–2a Underframe in the Longitudinal Vertical Plane

A calculation scheme for vertical oscillations of a 2a–2a type underframe is proposed. A system of six second-order differential equations describing oscillations in the vertical longitudinal plane is derived. A model of a locomotive section is built in the MathLab program using the Simulink application. The functions of body oscillation in the longitudinal vertical region of locomotive movement over time and the body tilt in the longitudinal vertical region of locomotive movement over time are determined.
