【摘要】：本文首先設(shè)計(jì)了激光通信儀的機(jī)械結(jié)構(gòu),基于ANSYS平臺(tái)對(duì)轉(zhuǎn)臺(tái)進(jìn)行了有限元分析,靜力特性分析時(shí)結(jié)果滿足強(qiáng)度和剛度的要求,動(dòng)態(tài)特性分析時(shí)結(jié)果滿足諧振的要求。其次,對(duì)跟蹤轉(zhuǎn)臺(tái)進(jìn)行了運(yùn)動(dòng)學(xué)與動(dòng)力學(xué)建模,得到了相應(yīng)的運(yùn)動(dòng)學(xué)與動(dòng)力學(xué)方程。使用ADAMS動(dòng)力學(xué)仿真軟件,對(duì)方位軸系和俯仰軸系分別單獨(dú)加載搖擺、勻加速、勻減速及勻速運(yùn)動(dòng),得到兩軸系單獨(dú)運(yùn)動(dòng)時(shí)驅(qū)動(dòng)電機(jī)轉(zhuǎn)矩的輸出情況;接著對(duì)兩軸系同時(shí)加載運(yùn)動(dòng)函數(shù),得到不同耦合運(yùn)動(dòng)時(shí)系統(tǒng)驅(qū)動(dòng)電機(jī)輸出轉(zhuǎn)矩曲線。對(duì)比分析不同情況下兩軸系驅(qū)動(dòng)電機(jī)輸出轉(zhuǎn)矩曲線,得到了兩軸系之間運(yùn)動(dòng)的相互影響關(guān)系,為電機(jī)的選擇提供參考,并為轉(zhuǎn)臺(tái)物理樣機(jī)的設(shè)計(jì)及優(yōu)化提供了一定建議。最后,基于CATIA的虛擬裝配環(huán)境,對(duì)激光通信儀簡(jiǎn)單地進(jìn)行了裝配仿真模擬,優(yōu)化裝配序列、路徑,并進(jìn)行了干涉分析,為激光通信儀的實(shí)際裝配提供了參考意見。
[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.
