The dynamic simulation of hyperbolical-cam piston engine for UUV is performed utilizing co-simulation in ADAMS and Matlab.First,a simplified model of the engine is established by using UG through down-top design method,and imported into ADAMS to create a virtual prototype,which is followed by the validation using relevant engine test.Second,the engine control simulation model is built by Matlab/Simulink.Third,the co-simulation is implemented based on ADAMS/Control and Matlab/Simulink.Then,the forces between key components in different complexion are provided through dynamic analysis,thus the strength of key components are checked.
