| 摘 要： | 用刚度—质量—阻尼模型分析在地面振动试验条件下带隔振器的卫星振动传递函数,得到隔振前后振动传递函数与卫星模态阻尼、卫星频率下降率和隔振器损耗因子的关系。据此关系,从抑制共振响应峰值和隔离中高频振动两方面提出了整星隔振器刚度和阻尼设计的若干准则。

| Abstract: | The transfer characteristic of a satellite with isolators was analyzed in the ground vibration test state by a stiffness-mass-damper model.The vibration transfer function was expressed in three dimensionless parameters which are the satellite's modal damper factor,the satellite frequency decreasing ratio and the isolator loss factor.From this transfer function,some principles for isolator design were established to restrain the resonance of the satellite-isolator system and to isolate the response in higher frequency domain. |
