Abstract

The invention mainly relates to a dynamical joint simulation analysis method of a door system of a rail transit vehicle, and the method mainly comprises the steps as follows: (1) a system is subjected to three-dimensional modeling and a three-dimensional model is converted to a neutral file in a SolidWorks environment to be imported into ADAMS (automatic dynamic analysis of mechanical systems); (2) the modal analysis of a flexible body component is conducted in Ansys, and converted to a neutral file to be imported into the ADAMS to replace a corresponding rigid body model; (3) a simulation model is preprocessed; (4) a system control model is built in Matlab, the door system is subjected to simulation control by an ADAMS/Control module to accomplish the kinematic and dynamical simulations of the whole system; (5) an experimental test platform is constructed, and a motion experimental test of the system is conducted; (6) a simulation result is compared with an experimental result, and the model is modified continuously; and (7) motion simulations of opening and closing a door and simulating a practical operating condition are conducted to search an optimal door control system mode.

Description

technical field [0001] The invention relates to an analysis method for co-simulation by using SolidWorks, Ansys, ADAMS and Matlab, in particular to a co-simulation analysis method for dynamics of a rail vehicle door system. Background technique [0002] With the rapid development of rail transportation, the demand for rail vehicles is increasing year by year. As a key large-scale component in the rail vehicle system, the design of the rail vehicle door system has aroused great attention from the rail vehicle design, operation and transportation management departments. The safety of rail vehicle door systems directly affects the safety of rail vehicles. In recent years, the reliability design of high-speed vehicle systems has become one of the important topics studied by scholars at home and abroad. [0003] The traditional method of track door system design is to first analyze the requirements of the door system, then produce and develop a prototype, and then carry out the w...
