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。
A cushioning device combining spring deformation and rigid displacement is discussed. The basic principle is to absorb the spring on a moving piston to deform and make the spring move rigidly at the same time. Among them, the moving speed of the piston flow through the flow chamber control to achieve the extended impact time and reduce the impact of the purpose. Through the experimental study found that the design of the buffer device can double the buffer capacity. Since the buffering mechanism of the device is purely mechanical and the fluid control medium is normal water, the buffering device is particularly suitable for the collision problem of underwater massive materials.
