STROK Select damping constant from graph 1: Hight : Medium : Low lank: with cap N: without cap Why do we need shock absorbers? The simplest method to increase productivity is to raise machine operation. t often accompanies with excessive vibration and noise, damage to machines and products and decreasing in machine life. Most important of all, safety has to be sacrificed to a certain degree because of large shock forces generated. MNMN shock absorbers are developed to provide linear deceleration and therefore solve these problems. They can stop or change direction of moving objects smoothly and quietly without any compromising in safety. MNMN shock absorbers are ideal for energy absorption and are being used whenever shock forces occur. The advantages of using shock absorbers include 1. To increase production rate.. To extend machine life.. To simplify equipment design.. To reduce maintenance cost.. To reduce vibration and noise levels. principles of shock absorbers ll series of MNMN shock absorbers are of such construction as shown in the following drawing. Muffer On the piston rod moves into the shock absorber and the hydraulic fluid is pushes into accumulator to produce resistant uter tube force. Owing to special spacing and sizing of orifices, the pressure in the inner tube remains constant throughout the entire stroke. ccumulator y providing a linear deceleration, a MNMN shock absorber brings the ing object to stop smoothly and quiet. t the end of the stroke, the return spring Orifices pushes the piston to its original piston for next cycle. Return spring mpact force mpact cap Piston rod luid Piston heck valve omparison of shock absorbing of dash pots, rubber materials springs, cylinder cushion and shock absorbers n case of MNMN shock absorbers compared with other buffering devices, such as spring, dash pots, air buffers, or rubber materials, resistant forces are different from one another. Only MNMN shock absorbers can stop a moving object smoothly and quietly from the beginning to the end of stroke. igure 1 shows a scheme of comparing shock forces generated by different cushioning materials. Through special design of fluid metering system, MNMN shock absorbers can provide a constant resistant force or linear deceleration throughout the entire stroke, all the kinetic energy of the moving object is converted into heat and dissipated into the air. Springs, air buffers and rubber materials only dissipate a small portion of the kinetic energy and store the remaining in elastic energy form. Therefore, large resistant forces and rebounding forces are inevitable near the end of the stroke. Without a delicate metering system, a dash pot will produce a large peak force at the beginning of the stroke. orce ylinder cushion dash pots Springs and PU Shock absorbers onsiderations for selecting shock a absorbers 1.Moving direction.
