Fault Modeling and Simulation Analysis of Multi-hydraulic Cylinder System Based on AMESim
In order to evaluate the reliability and fault risk of the multi-hydraulic cylinder system scheme,a multi-hydraulic cylin-der system fault simulation model was established based on AMESim modeling and simulation platform.The composition and hydraulic principle of a multi-hydraulic cylinder system were introduced.Based on AMESim,the simulation model of the multi-hydraulic cylinder system was established and the simulation models of the oil supply system,the lifting system and the locking system and the working mode of the whole system were briefly introduced.The typical fault patterns were modeled by fault injection.Finally,taking the simulta-neous mode as an example,the influence of different fault modes on the multi-hydraulic cylinder system was analyzed,and the changes of operating parameters of each sub-hydraulic cylinder in typical fault modes were identified,so as to adjust the system design scheme.The simulation results show that the multi-hydraulic cylinder system simulation model can be used to realize the simulation analysis of different tasks and functions in multi-cylinder and multi-fault mode,which provides reference for subsequent multidisciplinary coupling simulation analysis,multi-parameter optimization and physical design of multi-hydraulic cylinder system.
