The Global Passive Shock Absorber Market is growing at a faster pace with substantial growth rates over the last few years and is estimated that the market will grow significantly in the forecasted period i. A shock absorber is a mechanical device designed to smooth out or (A slight wetness) damp a sudden shock impulse and dissipate kinetic energy. Main components of shock absorber consist of following part (see Fig. wanderlodgegurus. rubber bushing. The shock absorber we designed for an OEM (1 kg lighter/ vehicle) has helped reduce 1,000 MT of steel usage until now. INTRODUCTION Magnetic suspension system is mainly based on the property magnets that like poles of magnets repel each other. Generally, the shock should be compressed 40% - 50% of its travel at ride height. Hajzmanˇ a a Section of Materials and Mechanical Engineering Research, SKODA Vˇ YZKUM s. Measuring time does not generally exceed 1 to 2 minutes. •Stress gra. One design consideration, when designing or choosing a Shock absorber is where that energy will go.
