The Main Structure Of The Monomer Type Without Collision Avoidance Stereo Garage Reliability Design Research

In recent years, with the growth of economy, more and more cars. The increase of the number of the car at the same time bring convenience to people travel with the increase of the static traffic problems. Treasure land, urban land scarce land the contradiction between the increasing parking demand intensified, parking Spaces, the spatial development is the necessary way to solve this contradiction. At present, the stereo garage are varied, the different function, three-dimensional garage without collision avoidance type has been widely used for its unique design concept. In view of the garage is the expensive cars, and there is no unique structure, avoid solid carport is complex, its dynamic performance is good or bad in the process of operation not only directly affects the normal operation of the stereo garage, but might also poses a serious threat to vehicles and personnel, and therefore it is necessary for the reliability of the stereo garage without collision avoidance type of extensive and in-depth research.This article mainly has carried on the following several aspects work:(1) First, finite element analysis software ANSYS is used for key parts of the car front wheel pin actively entity model is analyzed with mechanics, and it is concluded that the stress distribution situation; On the basis of static finite element analysis, using a monte carlo random sampling method in active the car front wheel pin paper repeatedly sampling on the stress curve of the reliability of the parts; Through the same process in this paper, it is concluded that the three-dimensional garage of 16 reliability parameters of key parts. The results of the design of key parts for provides a new train of thought.(2)According to the structural characteristics of no collision avoidance stereo garage and reliability test data of fault location, pattern classification, three-dimensional garage with stereo garage machine fault, for top event subsystem faults as intermediate events, with failure mode in order to establish the whole machine fault tree bottom event structure diagrams, express no avoid three-dimensional garage internal relation between the failure event, logical relationship and the route of transmission, it is concluded that the minimum cut set, calculate the failure rate of the machine.(3)Based on the reliability of the finite element analysis software ANSYS analysis module, based on kingview 6.55 software development platform, designed a more convenient, more professional without avoid parking reliability analysis software. Solve interface when the complete reliability analysis in ANSYS optimized, and the problem of inefficient and applies the system in xuchang Xu Ji parking system co., LTD. Project: "2000 kg no avoid three-dimensional parking equipment research", also is similar to other forms of three-dimensional garage reliability analysis provides a feasible method.
