摘要 提出一种旋转机械主被动混合隔振虚拟样机方法,并通过实验对虚拟样机仿真结果进行验证。首先对柴油发电机组电磁-气囊主被动混合隔振系统进行建模,然后对电磁作动器进行理论分析与实验,得到电磁作动器输出力特性。通过利用多刚体动力学软件ADAMS与MATLAB/SIMULINK联合,搭建柴油发电机组主被动混合隔振虚拟样机系统,对虚拟样机进行了冲击摇摆的计算,并进行控制算法与主被动混合隔振研究,同时搭建了物理样机实验平台并对仿真结果进行实验验证。结果表明:主被动混合隔振虚拟样机所得结果与实验结果相吻合,可以作为主被动混合隔振系统研制的重要依据。 A technique of rotating machinery’s active-passive hybrid vibration isolation virtual prototype was proposed and simulation results of virtual prototype were verified through tests. Firstly, the dynamic model for a diesel engine-generator set’s electromagnetic-airbag active-passive hybrid vibration isolation system was established. Then output force characteristics of an electromagnetic actuator were obtained through theoretical analysis and tests. Secondly, the diesel engine-generator set’s active-passive hybrid vibration isolation virtual prototype system was constructed adopting the multi-rigid body dynamics software ADAMS combined with MATLAB/SIMULINK to perform shock and sway computation, and study the control algorithm and active-passive hybrid vibration isolation simulation for the virtual prototype system. Thirdly, 6 hybrid vibration isolators were used to set up a physical prototype test platform for the set to conduct test verification for the above simulation results. The results showed that the active-passive hybrid vibration isolation virtual prototype system’s simulation results agree well with test results, so this proposed technique can be taken as an important base for studying and manufacturing active-passive hybrid vibration isolation systems.
