Shock-Waves Protection Mechanism

Shock waves of high amplitude (both single and serial) bear high energy, and off-design dynamic overloads are produced at 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, and it will absorb a part of energy and minimize peak mechanical moments. In the event of an abnormal situation, when an incident wave creates the excessive mechanical moment and the working hydrocylinder experiences overloads because of resistance of hydro mains, inertness of working liquid mass and inertness of mechanics as a whole, load on the main lever axis increases, force applied to the rod of damping cylinder increases too, and while moving, it absorbs a part of energy in the external hydraulic accumulator, which in turn prevents the damage to the mechanical parts.
