【摘要】：本文首先设计了激光通信仪的机械结构,基于ANSYS平台对转台进行了有限元分析,静力特性分析时结果满足强度和刚度的要求,动态特性分析时结果满足谐振的要求。其次,对跟踪转台进行了运动学与动力学建模,得到了相应的运动学与动力学方程。使用ADAMS动力学仿真软件,对方位轴系和俯仰轴系分别单独加载摇摆、匀加速、匀减速及匀速运动,得到两轴系单独运动时驱动电机转矩的输出情况;接着对两轴系同时加载运动函数,得到不同耦合运动时系统驱动电机输出转矩曲线。对比分析不同情况下两轴系驱动电机输出转矩曲线,得到了两轴系之间运动的相互影响关系,为电机的选择提供参考,并为转台物理样机的设计及优化提供了一定建议。最后,基于CATIA的虚拟装配环境,对激光通信仪简单地进行了装配仿真模拟,优化装配序列、路径,并进行了干涉分析,为激光通信仪的实际装配提供了参考意见。
[Abstract]:In this paper, the mechanical structure of the laser communication instrument is first designed, and the finite element analysis of the turntable based on ANSYS platform is carried out. The results of static analysis meet the requirements of strength and stiffness, and the results of dynamic characteristic analysis meet the requirements of resonance. Secondly, the kinematics and dynamics of the tracking turntable are modeled, and the corresponding kinematics and dynamics equations are obtained. By using ADAMS dynamic simulation software, the torque output of the driving motor is obtained when the azimuth shafting and the pitch shafting are separately loaded with rocking, uniform acceleration, uniform deceleration and uniform speed motion. Then the motion function of the two shafting is loaded at the same time, and the output torque curve of the system driving motor is obtained under different coupling motion. By comparing and analyzing the output torque curves of the two shafting drive motors under different conditions, the interaction between the motion of the two shafting is obtained, which provides a reference for the selection of the motor, and provides some suggestions for the design and optimization of the physical prototype of the turntable. Finally, based on the virtual assembly environment of CATIA, the assembly simulation of the laser communication instrument is simply carried out, the assembly sequence and path are optimized, and the interference analysis is carried out, which provides a reference for the practical assembly of the laser communication instrument.
