摘要
讨论了一种弹簧变形与刚性位移组合的缓冲装置,其基本原理是将吸能弹簧架在一个移动活塞上,让弹簧受力变形并使其同时作刚性移动。其中,活塞的移动速度通过液流腔的流量控制,达到了延长冲击时间和减缓冲击力的目的。通过试验研究发现,设计的缓冲装置能成倍的提高缓冲能力。由于装置的缓冲机构为纯机械式,且流控介质为普通水,所以,这种缓冲装置特别适用于水下大质量物质的碰撞问题。
This paper discussed a buffer device combined spring deformation with rigid displacement. The basic principle was that the energy-absorbing spring was set up on the moving piston. When the spring was deformed by forced, it would move rigidly. The moving speed of the piston was controlled by the flow chamber to extend the impact time. Therefore, the impact force would be reduced. The design of buffer device could improve buffering capacity manyfold during the experiments. The buffer mechanism was purely mechanical, and the fluidic medium was the ordinary water. Therefore, it offered a solution to the impact of massive objects underwater.
