一种大型太阳模拟器机械系统的设计

针对太阳模拟器的光出射角度不可变和太阳模拟器温控系统不好解决的问题，提出了一种大型太阳模拟器方位和俯仰回转机构及其控制系统和太阳模拟器温控系统的解决方法。方位与俯仰回转机构采用U-T型框架结构，轴系采用滚动轴承支撑结构，机械传动系统采用蜗轮蜗杆传动机构，温控系统采用水冷方式，通过计算机控制系统，完成对方位与俯仰回转机构转角的角位置控制，进而得到不同出射角度的出射光路，通过温控系统完成对氙灯和积分器的冷却。通过对比，发现这种回转机构为试验验证能带来更多的便利，温控系统能有效的控制模拟器温度。结果表明，设计出的方位回转±180°、俯仰回转±30°、转角精度≤0.5°的回转机构以及太阳模拟器温控系统能够满足使用要求。

Design of A Large-scale Solar Simulator Mechanical System

Aiming at the problems that the solar simulator light exit angle is immutable and the temperature control sys-tem and solar simulator is solved difficultly. A large-scale solar simulator azimuth and elevation rotary mechanism is proposed; and the solution of temperature control system of solar simulator is proposed. UT-frame structure is used as azimuth and elevation rotary mechanism;rolling bearing support structure is used in shafting, worm and gear me-chanical is used in transmission mechanism, water-cooled mode is used in temperature control systems. The azimuth and elevation angle of the angular position of the rotating mechanism are controlled in order to obtain different angles of the outgoing light emitted path by computer control systems;the xenon lamp and integrator are cooled through a temperature control system. By being contrasted, it is found that the rotary mechanism for the experimental verification can bring more convenience, the temperature control system can effectively control the temperature of the simulator. The results show that the design of the azimuth rotation ±180°,tilt swivel ±30°,angle accuracy ≤0.5° slewing mecha-nism and solar simulator temperature control system can meet the requirements.
