Title Design of a hydraulic buffer
Abstract With the progress of the times and the development of science and technology, the dependence on the machine equipment is becoming more and more deeply. When a test launch device launch, the gun barrel to rotate upward and downward motion.The falling movement must be controlled in a certain period of time but the whereabouts in place must control the impact velocity. This design is based on the application of engineering, and the principle and structure of the hydraulic buffer used in the test device are studied.A series of parameters of the test launch device from the highest point drop process are analyzed.Combined with the subject of hydraulic bumper specific size requirements, function relationship of buffer throttling area on the cushion stroke was calculated. The structure model of the hydraulic buffer is established by using the function relationship and the dimension of the project.Combined with the actual situation and the difficulty of the process, the structural model of the hydraulic buffer is optimized.

1 绪论 1.1 引言 缓冲器在现代工业领域得到越来越广泛的应用。在起重运输、铁道车辆、港口机械、冶金等机械设备的运行过程中，缓冲器起到一个减缓刚性碰撞的作用。它能够将冲击载荷的作用时间延长，并将冲击载荷的能量加以吸收和转化，进而起到保护设备的作用。随着现代化生产中应用缓冲器的各种机械迅速地向自动化、高速化、大规模化的方向发展，因各种错误操作而发生事故的概率也会有所增加，冲击强度和产生的破坏性大大增强，因此，对缓冲器的性能要求也越来越高[1]。
