Study on spare parts requirement modelling of multi-component system under stochastic slock condition

摘要

In the field of modern industry,equipment is becoming larger and more complex.Some precision components,especially electronic components and mechanical components,will suffer from external vibration and shock and traumatic failures during operation.Therefore,the analysis of the failure process of multi-component system under the condition of common cause failure is of great significance to improve the guarantee efficiency of multi-component equipment system.When multi-component equipment system is running,the problem of traumatic failures of components under shock is not considered in the calculation of spare parts demand for the system.Based on the analysis of the correlation between equipment degradation failure and shock failure,a spare parts demand calculation model under random shock is established in this paper.Finally,the feasibility of the method is verified by an example.The simulation results show that the model can solve the problem of spare parts demand calculation of multi-component mechanical equipment under random shock.
