Abstract:

According to the research status analysis of maintainability quantitative parameters verification, building the product maintainability quantitative parameters verification system based on Virtual Reality. First of all, to build the system's overall framework; Secondly, the key technology of authentication system maintainability quantitative indexes is expounded; Moreover, in military specifications maintainability quantitative parameter estimation method was improved, constructs a model of MTTR validation suitable for the complex equipment; Finally, carrying MTTR simulation for a certain type of vehicle transmission device in the authentication system, and doing MTTR validation by the MTTR estimation model. The result shows that the verification results obtained by the virtual simulation experiment and real vehicle test results are the same, which has high credibility. The method provides significant reference value for paralleling maintainability quantitative parameters verification in product development stage.
