Shock absorber

Shock Absorber

A Shock Absorber is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).

Types of Shock Absorbers

Shock absorbers come in two primary types: spring-based shock absorbers and strut-based shock absorbers.

Spring-based Shock Absorbers

Spring-based Shock Absorbers use a spring element to absorb shock. The spring is usually made of high-strength steel and is often coiled. When a shock is applied, the spring compresses to absorb the energy, then slowly decompresses to release the energy back out.

Strut-based Shock Absorbers

Strut-based Shock Absorbers use a strut element, typically a gas-filled cylinder, to absorb shock. The strut has a piston and a cylinder that contains a gas or liquid. When a shock is applied, the piston moves, compressing the gas or liquid to absorb the energy.

Applications

Shock absorbers are used in many applications, including vehicles, industrial machinery, and infrastructure. In vehicles, they are an integral part of the suspension system, reducing the effect of traveling over rough ground, leading to improved ride quality and vehicle handling.
