| 摘要常规火箭（导弹）武器采用火药作为发射动力源，但是在此过程中会产生推力偏心以及高温高压燃气流，会对定向器产生灼伤。所以本设计课题以压缩空气为动力源，通过开口缸和活塞将压缩空气的内能转化为机械能，从而发射火箭弹（导弹）。采用压缩空气为动力源不会产生高温高压燃气流，而且空气能源取之不尽用之不竭，可以说资源丰富。由于开口气缸较大，所以在杠结构设计时，为了达到高速发射，活塞与密封带的结构尤为重要，最后采用缸内受力仿真进行开口变形大小确定。在确定杠结构以后，需要评估开口气缸，纺锤形活塞，以及杠端盖的质量。最后进行各发射方案，以及优劣对比。最终确定开口气缸等各零件的三维以及二维图。50075 毕业论文关键词 压缩空气 冷发射 倾斜发射 垂直发射 无杆气缸 Title The design of Rodless cylinder compressed air Abstract Conventional rockets (missiles) weapons using gunpowder as the transmission source of power,but in the process will produce thrust eccentric and high pressure gas stream will redirectorburns. So the design task by compressed air as power source, through the opening of thecompressed air cylinder and piston internal energy into mechanical energy, thereby launchingrockets (missiles). Using compressed air as power source does not produce high pressure gasstream, inexhaustible energy and air, it can be said is rich in resources. Since the opening of alarge cylinder, so the bar structural design, in order to achieve high-speed launch, the structure ofthe piston and the seal tape is particularly important, and finally the use of force by the cylinderdeformation simulation performed to determine the size opening. In determining the barstructure, the need to assess the opening cylinder, fusiform, and the quality of the end cap of thepiston bar. Finally, each transmission scheme, and comparison of the pros and cons. Finalize theopening of the cylinder and other parts of the three-dimensional and two-dimensional drawing.
