N2 - The deflection of some supports, which is caused by the external force or the tolerances in the manufacture and assembly procedure, will induce seizure of the mechanism with multi-support axis. However, only a few researchers investigated the seizure reliability of mechanism, and they were focused on the simplified models of some simple mechanisms. In recent years, the reliability simulation analysis based on computer simulation technique is widely adopted to improve the reliability of the complex mechanism in practice, and the reliability analysis is fulfilled by introducing the random parameters to the mechanism model in the simulation. In this paper, the reliability analysis for the multi-support axis seizure of a door mechanism, which is caused by the assembly tolerance, is investigated. The rigid-flexible coupling model of the door mechanism is built in the commercial software LMS Virtual.Lab. The parameterized expression of the assembly tolerance is introduced to the simulation by the advanced mesh transformation so called mesh morphing technique. The results data corresponding to the failure mode are obtained based on plenty of simulations using the parametric model. Then, the approximate model for the limit state function is generated using the support vector regression machine based on the results data. Finally, the reliability analysis and evaluation for the multi-support axis seizure of the door mechanism are achieved using the approximate mode. In our research, an integrated platform for mechanism reliability simulation analysis is also developed using the commercial software LMS Virtual.Lab, and the simulation results show that the developed platform might be efficient for the reliability analysis of complex mechanism.
