对某机动三坐标雷达天线折叠机构进行运动仿真分析,根据该雷达天线折叠机构特点,定义机构的连接及运动关系副,机构的原理图,运动输入函数,通过对不同设计参数求解,得出相应参数天线阵面角加速度、角速度的响应函数图,分析比较运动时间与角加速度、角速度的变化关系,找出最佳运动时间。

The kinematical simulation of antenna folding mechanism for a mobile 3D radar is presented in this paper.According to the characteristic of antenna folding mechanism,this paper provides the definition of joint and kinematical pair,elemental drawing and kinematical input function.Based on the different design parameters,this paper educes response function drawings of angle velocity and angle acceleration of antenna,analyses the relation of moving time,angle velocity and angle acceleration,finds the best time finally.
