摘　　要：为解决现有内窥镜存在的使用时间长、手指易疲劳问题,提出了电机助力系统结构,对关键零部件抱紧装置进行优化设计与试验。首先,利用ADAMS软件分析得到抱紧装置摩擦片和助力轴套的角速度曲线图,验证了装置的平稳可靠;再根据不同电机参数下摩擦片的共速时间,结合MATLAB软件处理数据得出2个参数间的4阶关系式并求得最优参数解;最后搭建电机助力系统样机平台,针对不同电机转速分别进行试验。结果表明,当电机转速为52.5 (°)/s,即助力轴套转速为39 (°)/s时共速所需时间最少,即电机助力质量最优。试验实例与运动学仿真结果进行对比存在4.9%的误差,在许可范围内,再次验证了装置的可行性。In order to solve the problem of finger fatigue caused by prolonged use of existing endoscopes,the motor power system structure wss proposed,and the key component holding device was designed and tested.Firstly,the angular velocity curve of the friction plate and sleeve was obtained by ADAMS software to verify the stability and reliability of the device.Secondly,ADAMS software was used to obtain the common speed time of friction plate under different motor parameters,combined with MATLAB software data processing,the fourth order relationship between two parameters was obtained and the optimal parameter solution was obtained.Finally,the prototype platform of the motor power system was set up,and the experiments were conducted for different motor speeds.The results showed that,when the motor speed was set to 52.5(°)/s,then the minimum time was required for the power shaft sleeve speed was 39(°)/s,and the motor power quality was optimal.There was a 4.9%error in the comparison between the test example and the kinematic simulation results,which once again verified the feasibility of the device within the scope of the permit.
