The Simulator System Of Relative Location Of The Endface Connection Device On The Basis Of Virtual Model Machine Of ADAMS/Rail

In 21th century, Chinese railway construction welcomes the new opportunity of Great-leap-forward development, controlling and applying new search theory and design method, progressing creation of locomotive vehicle design, is the important way to deveolp our country railroad locomotive vehicle technical. Defining the reasonable gap between each parts of vehicle and the vehicles, is advantageous to avoiding vehicle to generate an interference in the run-time, and raise vehicle run-time performance. In order to raise the level of our country vehicle's research, design and production, this text is on the basis of computational multibody systems dynamics and parametric technique theoretic, make use of menu and dialogue box editor and macro command method, deliver a simulation system for relative position of endface connection device at ADAMS/Rail software platen and ADAMS command language environment.In the run-time, when the train is subjected to traction, braking action or passing curve, turnout and variable-point, between each parts of vehicle and two close cars, all can generate relative running. This text analyzed the mathematics principle of relative location of the endface connection device and the theory of computational multibody systems dynamics of the virtual model machine.Through the analysis characteristics of virtual machine product applied by railroad vehicle, this text select ADAMS/Rail for a platform of relative location of the endface connection device simulator system, it is an excellent kinetics analysis software. Owing to the thorough search for common method to the second developing, it select the command language environment in ADAMS, making use of menu and dialogue box editor and macro order method to progress the second developing.Based on "The template create- subsystem create-train system assemble" mode that adopted by ADAMS/Rail, created some template and subsystem of the car body, bogie and line, they are stored in the catalog document in correspond with the second develops system by databases form and can be convenient to use while train assembly.According to the command language, custom menu and dialogue box to develop the interface of the relative location of the endface connection device simulator system, the system has a good interface of humancomputer and fault tolerant capability, can choose the car body, bogie, coupler, lines conveniently on your own, can automatically assemble two car train system, and carry on a modification for car body, bogie shape size and attribute document conveniently. At the same time pass create a specific request, can carry on opposite location of car port and vehicle kinetics performance analysis. The function of the system is abundant,, the operation is simple and it can be easy to control.The system is on the basis of virtual model machine product, associative with the development level of our country vehicle business, can lower the shape designer's operation capacity, raise the design of products efficiency, shorten the develop cycle, it have certain engineering usage worth.
