一、前言人造卫星上用的设备,要求体积小,重量轻,应能经受发射时机械环境的考验,同时,在宇宙空间温差大和真空度高的条件下能正常工作。为了满足这些要求,必须选用重量轻,刚性好,热膨胀系数小的功能和性能第一流的材料。因此,零件的制造工艺就要与各种各样的材料相适应,同时还必须适应从金属材料到碳纤维增强塑料等合成材料的变化。日本在独自进行宇宙开发的过程中,制造工艺与设计技术并重,都是主要课
I. INTRODUCTION Equipment used on satellites requires small size and light weight and should be able to withstand the mechanical environment during launch. At the same time, it can work normally under conditions of large temperature difference and high degree of vacuum in space. In order to meet these requirements, we must choose the light weight, good rigidity, small thermal expansion coefficient of function and performance of the first-class materials. Therefore, the parts manufacturing process should be compatible with a wide range of materials, but also must adapt to changes from metal materials to carbon fiber reinforced plastics and other synthetic materials. Japan alone in the process of developing the universe, both manufacturing technology and design technology, are the main lesson
