卫星包装箱的随机隔振优化分析

The Stochastic Optimization Analysis for the Isolation of the Packaging Case for Satellite

用钢丝绳隔振器将卫星包装箱支承在运输车上,将卫星与车辆简化为二自由度体系,优化分析了在随机路面上行驶时使包装箱响应最小之隔振参数,对实测得到的钢丝绳减振器的非线性迟滞性能作了描述,提出了统计线性化分析的方法。

Wire-cable isolators are used to isolate the packaging case in satellite vehicle tra-velling over the road with random surface in order to reduce the vibration of asatellite. The satellite and its vehicle are simplified by a 2 D. O. F. system, and itsresponse is to be minimized by an optimization analysis with respect to isolation para-meters. The nonlinear hysterestic behavior of the wire-cable measured by experimentsis described by a simple mathematic model and the overall system was analyzed by astatistically linearized method.
