Abstract


With the mature of3d technology, virtual reality (VR) technology has obtained manyachievements and applied to many fields like automotive manufacturing, production,education increasingly as a kind of advanced man-computer interface technology, Thebiggest feature of virtual reality technology is to produce a three-dimensional environmentwith very similar simulation with reality, the user canconduct a series of behavior "immersion" to control the environment, so as to realizethe interactions with the virtual environment. Given the current rapid development ofautomobile industry in our country, auto continuous increasing of automation and more andmore complex structure of the automatic transmission, coupled with a bad workingenvironment and different levels of informal driving, make the transmission failure rate is onthe rise. These factors put forward high demands on vehicle maintenance and repairtechnology. We have found that there are still many problems existing in training system oftoday’s maintenance industry through investigation, the traditional single mode of traininghas high cost, low efficiency and poor sharing resource and so on, make it more and moredifficult to satisfy the demand of the market. These flaws strictly restrict the improvement ofthe level of vehicle maintenance and repair. How to effectively combined the virtual reality(VR) technology with the maintenance become the key research content in this paper.In this paper, the virtual reality of fault diagnosis system takes virtual reality as the coretechnology, combined with other related technology such as flash,3dmax and maintenancediagnostic method in today’s mainstream. The automatic transmission fault diagnosis systemplatform which is based on Virtools technology. Enhance students’ interest by the way ofman-machine interactive, teach through lively activities, contribute to completion of thetraining more effectively and corporate training costs, training quality has got a lot ofascension.The working conditions and technical parameters of automatic transmission is one ofthe important indicators of performance evaluation. Automatic transmission has got a widerange of application with fewer emissions, good ratio of performance and convenient, savinglabor and so on. As the automatic transmission constructed with integrated complex electromechanical and fluid systems, failure of one or more components will lead to faultwhich is difficult to effectively identify.This topic first introduce the research background and significance of gearbox faultdetection system, then illustrate something related to the virtual reality technology,combined with the structure of the automatic transmission, The system take common faultexamples of Mazda transmission as the research target, expounds the concrete process oftrain of thought. Finally combined the Virtools,3d Max and Action Script3.0technologywith each other, realize the man-machine interactive virtual simulation of fault diagnosis.
