【摘要】 为了满足某空间光学相机成像时需求,设计了一种一台步进电机同时驱动两套成像系统的凸轮运动机构。首先,详细分析了项目需求的特点,接着,对比了常用的驱动机构应用于本项目中存在优缺点,然后,选择了两凸轮同轴相差180°相位安装的方案,并对凸轮曲线进行了详细设计,最后完成了机构的详细设计并开展了运动学仿真,验证了设计的合理性和准确性,可以满足空间相机成像时同步的要求。更多还原

【Abstract】 In order to meet the demandof increasing efficacy for space camera,a synchronous mechanism was designed which constitute of two cameras drived by one step motor.Firstly,the special demands of the object was analysized.Secondly the motion mechanisms which in common used were contrasted.Then the cam mechanism was choosed and assemblied in one axis with 180°angle,and the curve of cam was calculated.Finally,the model of ground speed compensation mechanism was built by UG and simulated with Adams.It is proved the compensation mechanism is reasonable and veracious.更多还原
