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. MNDMN 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. MNDMN 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. 3. To simplify equipment design. 4. To reduce maintenance cost. 5. To reduce vibration and noise levels. omparison of shock absorbing of dash pots, rubber materials springs, cylinder cushion and shock absorbers n case of MNDMN 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 MNDMN 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, MNDMN 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. out a delicate metering system, a dash pot will produce a large peak force at the beginning of the stroke. orce Dash pots Shock absorbers ylinder cushion Springs and PU Operating principles of shock absorbers ll series of MNDMN shock absorbers are of such construction as shown in the following drawing. On the piston rod moves into the shock absorber and the hydraulic fluid is pushes into accumulator to produce resistant force. Owing to special spacing and sizing of orifices, the pressure in the inner tube remains constant throughout the entire stroke. y providing a linear deceleration, a MNDMN shock absorber brings the ing object to stop smoothly and quiet. t the end of the stroke, the return spring pushes the piston to its original piston for next cycle. onsiderations for selecting shock a absorbers 1.
