摘要
针对广角极光成像仪整机Z向冲击试验后探测器损坏的问题,提出在镜头组件与头部框架间设置隔振器的解决方法。首先,确定隔振方案为被动局部隔振; 然后,从材料、刚度和安装方式等方面完成金属橡胶隔振器的设计。接着,运用有限元方法对结构进行模态分析和冲击载荷响应仿真分析。最后,对广角极光成像仪整机产品进行了力学实验,实验结果与仿真分析结果一致。实验结果显示: 安装隔振器后,探测器位置测点的正弦振动加速度响应最大降低了26.2%,随机振动加速度响应最大降低了72%,冲击加速度响应最大降低了48%,说明该隔振器具有显著的减振效果。在实验完成后对产品进行检测,发现产品并无异常,说明结构设计满足要求。
Abstract
Solution method to set vibration isolator between lens module and head frame was proposed to avoid damage of detector after Z-direction shock test in whole machine of wide angle aurora imager. Firstly, vibration isolation scheme was determined as passive local vibration isolation; then vibration isolator design of metal rubber was accomplished in aspects of material seletion, rigidity determination and installation way design, etc. Modal analysis and simulation analysis of shock load response were conducted on structure by finite element method. Finally, mechanical test was carried out on whole machine product of wide angle aurora imager, and the results indicate that test results same as simulation analysis results. Accelerated speed response of sinusoidal vibration in measuring point of detector reduces by 26.2% maximally after installation of vibration isolator, and accelerated speed response of random vibration reduces by 72% maximally, and accelerated speed response of shock reduces by 48% maximally. It showed that the vibration damping effect of the vibration isolator was significant. The product is no abnormal after the test to satisfy requirements for structural design.
