摘　　要：火箭发射系统中的气驱油源设备在工作时会承受严酷的振动环境,因此须对其进行隔振设计。首先基于振动机理分析建立并求解六自由度隔振系统模型;继而对初步隔振设计方案进行相应振动工况的数值仿真及验证;并在此基础上对隔振器布局进行优化。结果表明:隔振器布局优化后的隔振设计方案可以确保气驱油源设备在x、y、z向的隔振系数均小于0.05,具有良好的隔振效果,且稳定性增强。所提出的隔振设计及优化方法可为类似系统的研制提供借鉴。The pneudraulic oil source equipment in a rocket launching system operates under severe vibration coditions.To mitigate these effects,a vibration isolation design is essential.Initially,a six-degree-offreedom vibration isolation system model was developed and solved based on an analysis of the vibration mechanism.Subsequently,numerical simulations and verifications were conducted on the preliminary isolation design scheme.Following this,the layout of the vibration isolators was optimized.The optimized vibration isolation scheme demonstrates that the vibration isolation coefficients for the pneudraulic oil source equipment in the x,y,and z directions are all less than 0.05,indicating effective vibration isolation and improved stability.The design and optimization methodology for vibration isolation presented in this paper can serve as a reference for the development of similar systems.
