大家知道,我国载人航天二期工程的关键技术是交会对接,而交会对接的关键产品是对接机构。它上面有118个测量动作、位置、温度的传感器,291个传递力的齿轮,759个轴承组合,11000多个紧固件,数以万计的导线、接插件、密封圈和吸收撞击能量的材料等。各种各样的接插件,密密麻麻的电缆线,看看都让人眼花缭乱,更不要说装配了。大家在电视转播中看到的两个重达8吨多的飞行器要在太空中实现对接,最主要的部件就是对接机构中的12把对接
As we all know, the key technology of China’s second phase of manned space project is rendezvous and docking, and the key product of rendezvous and docking is docking. It has 118 sensors for measuring motion, position and temperature, 291 transmitting gears, 759 bearing combinations, more than 11,000 fasteners, tens of thousands of wires, connectors, seals, and energy absorbing impact energy Materials and so on. A variety of connectors, dense cable, see are dazzling, not to mention the assembly. We see in the television broadcast of two weighing more than 8 tons of aircraft to achieve docking in space, the most important part is the butt institutions 12 butt
