摘要
为了能够准确地测量远程火箭炮在各种工况下关重件的载荷谱,真实地反映故障的发生和发展过程,提出了适合于大型复杂系统耦合仿真的协同仿真方案,建立了远程火箭炮完整的虚拟样机,较好地解决了机电液耦合、多碰撞变拓扑等建模难点,并通过台架试验和实装试验验证了虚拟样机的可信性。以同步器磨损失效过程为例,将同步器与啮合齿轮分别制成销试样和盘试样,基于摩擦磨损试验获取典型材料在不同工况下的磨损规律,结合虚拟样机仿真结果,计算其磨损失效寿命,为实现预知维修和精确化保障提供决策依据。
To accurately measure the loan spectrum of key elements of multiple long-range rocket system （MLRS）in various working conditions and truly reflect the occurrence and development process of fault,the paper puts forward a collaborative simulation scheme suitable for coupling simu-lation of large complex system,establishes a complete virtual prototype of MLRS,solve out the diffi-culties for modeling like mechatronic-hydraulic coupling and multiple collision and variable topology, then verifies the credibility of the virtual prototype by bench test and live-fire test .Taking the wear and failure process of synchronizer as an example,the paper makes synchronizer and a meshing gear as a pin specimen and a plate specimen respectively.Based on the tribological wear test,the paper draws the wear rules of typical materials under different conditions.Combined with the virtual proto-type simulation results,the paper calculates the wear failure life to provide decision-making basis for predictive maintenance and accurate support.
