Shock-Waves Protection Mechanism

Shock waves of high amplitude (both single and serial) bear high energy, and off-design dynamic overloads are produced in a collision with the structure; they inevitably result in mechanical breakages and equipment damages. To prevent such a phenomenon, a mechanical, pneumatic, or hydraulic damper may be implemented. This will absorb a portion of the energy and minimize peak mechanical moments. In the event of an abnormal situation, when an incident wave creates the excessive mechanical movement and the working hydro-cylinder experiences overloads because of resistance of hydro mains, inertness of working liquid mass and inertness of mechanics as a whole result in an increase load on the main lever axis, increased force applied to the rod of damping cylinder, and while moving, it absorbs a part of energy in the external hydraulic accumulator, which in turn prevents the damage to the mechanical parts.
