为了研究UUV热动力发动机的动力学性能,通过对发动机的剖析,应用UG软件建立了发动机的简化仿真模型,导入ADAMS软件环境中建立了发动机虚拟样机,并利用相关物理试验对样机进行了验证,然后结合MATLAB/Simulink软件建立了具有多个可控外部参数的发动机联合仿真动力学模型.通过联合仿真得到发动机关键部件的运动曲线和不同工况下关键部件之间的相互作用力,指出了降低相互作用力的途径,并联合ANSYS/Ls_dyna对主要传动零件进行了强度校核.仿真结果表明,联合仿真模型具有UUV热动力发动机的特点,对研究各参数与发动机动力学性能之间的关系以及结构优化均具有积极意义,为UUV热动力发动机的设计与改进提供了一种现代化方法和有效的依据.

To resoarchthe dynamic performance of thermal power engine for UUV,a multi-body dynamic model of the engine is established by using UG and ADAMS based on anatomizing the structure and principle of the engine in detail,which is followed by the validation using relevant engine test.Then the model is programmed by means of S-functions in Matlab/Simulink,and a data exchange interface with ADAMS is also defined.Third,the co-simulation is implemented on the model.The co-simulation experiments can give the motion curves and forces of the key parts in different complexions.Ways to reduce the forces are pointed.thus the strength of key components is checked The result shows that the model possesses features of UUV engine,and benefit for the research on the influences of the structural parameters variation on the dynamic performance and structure optimize of engine.The method is practical and available,it provides efficient and modern tools for reducing developmental cost and improving performance of UUV engine system.
