摘　　要：利用多体动力学分析软件ADAMS对某卫星微型雷达进行了运动学仿真,将影响卫星雷达精度的关键部件设为柔性体,以研究它们的弹性振动对雷达精度的影响。研究表明,由于柔性体的弹性振动存在,雷达镜面在原有刚性运动的基础上,会产生一定幅值的振动(X方向的影响最大,其振幅达到0.759mm),因此须提高主要支承框的刚度或改进运动副的参数。The mini-type satellite radar has been studied by the multi-body software package ADAMS. The key component of the minitype satellite radar is appointed as flexible due to its elastic vibrating influence on the precision of the radar. The conclusive remarks show there is an obvious vibration （0 -759 mm） in the direction of X on the mirror of the radar. Therefore, it is notable that the rigidity of the first support must be improved or the kinetic parameter must be modified.

关 键 词：卫星微型雷达 柔性体 弹性振动
