[0061] Example 2

[0062] In this embodiment, the door closing process of the door system is taken as an example to illustrate the simulation process of the present invention.

[0063] In the ADAMS simulation environment, set the external load, motor drive parameters, and the contact parameters of the rolling lock pin 2. Among them, the external load and the contact parameters of the rolling lock pin 2 are the same as those set in Embodiment 1, and the motor driving parameter is 50 r / min (reverse rotation). Under the above parameter settings, the simulation results of the displacement, velocity, acceleration and force of the rolling lock pin 2 are as follows Figure 7 ~ Figure 10 Shown. From Figure 7 ~ Figure 10 In the door system closing process, the locking device, especially the movement and force of the lock pin 2 can be deeply understood, and a conclusion similar to the above-mentioned door opening process can be drawn from this: that is, the rolling lock pin 2 and the sc...

Abstract

The invention belongs to the field of dynamic simulation analytical methods and discloses a dynamic simulation analytical method for a locking device of a rail traffic vehicle door system, which mainly includes the following steps: (1) performing three-dimensional modeling on parts of the locking device in Solid Works software environment, and switching a three-dimensional model into a neutral format file capable of being guided into automatic dynamic analysis of mechanical system (ADAMS) software; (2) guiding the neutral file into the ADAMS software to generate an ADAMS multi-body dynamic simulation model of the locking device; (3) performing preprocessing setting on the simulation model, setting material properties, joint, load and driving, and performing simulation calculation; (4) setting up an experimental test platform and performing experiment tests; (5) comparing simulation results with experiment results; and (6) performing locking device dynamic characteristics simulation analysis with different parameters and under different working conditions. The dynamic simulation analytical method builds a virtual prototype for the locking device of the door system, performs optimal design for the locking device, reduces development cost and shortens development period.
