| 摘 要： | 研究了隔振和抗冲击的组合优化设计问题.指出连续性设计思想的弊端,提出组合优化设计方法并建立了系统模型;分析了冲击隔离系统的极限性能及2种实现方法,一种是采用较大阻尼的单个线性元件;一种为无阻尼的多个线性刚度元件.仿真和试验结果表明:在缓冲器的刚度远大于隔振器的刚度时,具有线性刚度和阻尼的缓冲元件最佳阻尼比为0.4的结论仍然成立;通过结构优化设计.无阻尼线性元件同样能够实现性能最优化.

| Abstract: | The combination optimization design problem of vibration isolation and shock resistance system is studied in consideration of acoustical concealment performance and life force of ships.The weakness of design method based on continuity is pointed out and combination optimal design method is brought forward.Then the limiting performance of shock isolation system is analyzed and two realization methods are discussed.One method is to adopt linear stiffness component with large damping.The other method is to use... |
