摘要
摆盘发动机的振动是水下航行器噪声的主要来源.发动机的隔振设计以及在隔振条件下的振动特性成为研究关注的焦点.本文运用虚拟样机技术,建立了摆盘发动机在隔振条件下的三维模型.通过对发动机结构以及工作过程的模拟,对发动机主要部件进行了运动仿真分析.通过调整发动机的结构参数,研究了不同摆盘倾角时的部件受力与运动特性.通过调整发动机的隔振参数,研究了不同支承刚度时发动机的振动规律.研究结果对降低摆盘发动机的振动、提高发动机的机械效率具有参考意义.
Vibration caused by the wobble engine is the primary source of noise of the underwater vehicle.The vibration reduction design of the wobble engine and the dynamic characteristics analysis with vibration isolation device become central issue in the research.The virtual prototype technology was adopted to establish the model of the wobble engine with isolation device.Through the simulation of the engine structure and the working process,the movements of the main parts of the engine were analyzed.By changing the structural parameters,such as the inclined angle of the wobble plate,the forces and the moving characteristics of the parts were obtained.Furthermore,the vibration transmission laws were revealed by changing the vibration isolation parameters,such as the stiffness of the supporting springs.The results obtained may be used to reduce the vibration and raise the mechanical efficiency of the wobble engine.
