Study on durability allocation of mechanical system technique based on virtual prototyping

Durability allocation is an important part of durability design in mechanical system. Whether durability allocation is reasonable or not directly impacts the pertinence and validity of maintenance. When designing durability, lifetime data of components is necessary. The way to obtain lifetime is normally through test which takes so long and cost so much so that it cannot be adopted at initial stage. Tracked vehicles´ moving system is taken as study target. Fatigue life of key parts that is necessary in durability distribution of mechanical system is predicted using virtual simulation. Durability distribution of moving system is analyzed by the predicted life, which presents a scientific method of distributing durability in the design process.
