    研究天線機(jī)構(gòu)靜力學(xué)和運動特性是提高天線軌跡跟蹤精度的有效途徑,。首先,，對混聯(lián)天線機(jī)構(gòu)結(jié)構(gòu)進(jìn)行構(gòu)型描述；然后,，基于力旋量變換關(guān)系對混聯(lián)天線機(jī)構(gòu)各部件進(jìn)行受力分析,，借助數(shù)值計算軟件進(jìn)行靜力學(xué)求解，分析特定位姿混聯(lián)天線機(jī)構(gòu)驅(qū)動力的分布情況,，并將理論求解結(jié)果與仿真結(jié)果進(jìn)行對比,，以驗證理論分析的正確性；應(yīng)用有限元軟件分析混聯(lián)天線機(jī)構(gòu)特定位姿下的變形情況,，對混聯(lián)天線機(jī)構(gòu)的整體變形進(jìn)行評估,；針對混聯(lián)天線機(jī)構(gòu)進(jìn)行振動特性仿真，獲得混聯(lián)天線機(jī)構(gòu)特定位姿下的振型和固有頻率,；采用數(shù)值計算軟件進(jìn)行混聯(lián)天線機(jī)構(gòu)運動仿真,，獲得混聯(lián)天線機(jī)構(gòu)俯仰運動和方位運動的包絡(luò)空間；最后,，基于設(shè)計完成的關(guān)鍵零部件模型設(shè)計了混聯(lián)天線機(jī)構(gòu)物理樣機(jī),。

    Abstract:

    It is an effective way to improve the tracking accuracy of antenna by studying the static and kinematic characteristics of antenna mechanism. Firstly, the structure of the hybrid antenna mechanism was described. Secondly, the force analysis of each component of the hybrid antenna mechanism was given based on the wrench transformation relationship. The static solution of the hybrid antenna mechanism was carried out based on the numerical calculation software. The actuation forces distribution of the hybrid antenna mechanism with special positioning attitude were studied. The theoretical solution results were compared with the software simulation results to verify the correctness of the theoretical analysis. Thirdly, the finite element software was used to study the deformation of the hybrid antenna mechanism under special positioning attitude, and the overall deformation of the hybrid antenna mechanism was evaluated. The vibration characteristics of the hybrid antenna mechanism were simulated. Meanwhile, the vibration mode and natural frequency of the hybrid antenna mechanism under special positioning attitude were obtained. The motion simulation of hybrid antenna mechanism was carried out based on the numerical calculation software, and the motion envelope space of pitch and azimuth motion trajectory of the hybrid antenna mechanism was studied. Finally, the structure design of the key components of the hybrid antenna mechanism was carried out, and the physical prototype of the hybrid antenna mechanism was developed based on the key parts model. The research result can provide a reference for the design and development of antenna mechanism.
