The service life of a gear-type oil pump with variable displacement is affected by the reliability of its drive system. To analyse the reliability of the drive system and improve the service life of the oil pump, a virtual prototype model was established based on real conditions and multi-body dynamic theory. The model was validated according to bench test results. And simulation results were in good agreement with test results. A numerical method was used to simulate the dynamics model and the dynamic meshing forces of gear pairs were obtained. A reliability evaluation model of the drive system was built. The reliability of each part and the entire drive system were calculated. And system reliability was analysed and discussed when 45 steel or 40Cr was utilised as the material for the drive system. The results provided a foundation for the reliability design and the dynamic optimisation of a gear-type oil pump with variable displacement.

For a large scale series mechanical system composed of a great number of components, the component reliabilities allocated according to classical system reliability model are usually unrealistically high, even though the assigned target reliability for the system is quite low. Generally, system reliability can not be calculated from component reliabilities owing to the dependence among component failures. For the same reason, system reliability can not be simply allocated to the individual components according to traditional system reliability model. Based on comprehensive analysis to the controlling factors of component failure dependence, the present paper introduces new definition of system complexity and component complexity, presents load roughness based principle for system reliability allocation. According to such a principle, system reliability requirement can be reasonably allocated to components.

“…As one of the important parts of the car, car seat plays the role of supporting the driver in place, which ensures that its good field of vision and the performance of vehicle stability control at the same time reduce or avoid the hurt of the driver and crew in accident damage [9]. With the rapid development of automobile industry, the security performance of the car seat already affects vehicle ride comfort and safety, ergonomics, mechanical vibration, control engineering, material science for the integration of systems engineering, such as product [10] [11].…”
