主机气囊隔振系统抗冲击设计
|
摘要
为了改善主机的抗冲击性能,首先基于气囊限位装置的动力学模型,理论分析了系统响应峰值随限位器的间隙、刚度参数变化的趋势;然后,采用数值仿真的方法分析了限位器间隙、刚度、阻尼比和橡胶层厚度对主机隔振系统抗冲击性能的影响,并对主机气囊隔振系统的限位参数进行了设计,结果表明:通过气囊隔振装置限位参数的优化设计,可明显降低主机的冲击响应。
This paper focuses on the improvement of shock resistance performance of ship power plant. Firstly,based on the dynamic model of the displacement restrictor integrated in air spring,the theoretical method is used to analyze the effect of gap and stiffness on response peak. Then the nume-rical simulation methods are used to analyze the influence of gap,stiffness,damping ratio and rubber thickness of displacement restrictor on shock resistance performance of vibration-isolating system. Meanwhile,the parameters of the displacement restrictor integrated in air spring are designed. The results show that the impact response of the ship power plant can be reduced by the optimal design of the parameters of the air spring,thus significantly improving the shock resistance performance of the system.
