Hydraulic shock absorbers and its application

What are shock absorbers?

Shock absorbers are devices used for absorbing jolts and vibrations that is created in a machine. A shock absorber is a mechanical or hydraulic device designed to absorb and damp shock. This is done by converting the energy of the shock into another form of energy which is then dissipated. There are a number of shock absorbing materials like rubbers and polyurethanes that offer absorbing solutions to meet the specifications irrespective of its applications.

Why are shock absorbers essential?

Unwanted mechanical energy creates vibration, shock or noise and can pose a serious problem within mechanical systems. Finding the right shock absorbing material is extremely critical in developing an effective and efficient design.

Shock is a major cause of damage and failure in mechanical equipments and especially in case of electronic devices. Shock can be described as a short-duration event with large magnitude acceleration. A shock absorbing material needs to be introduced in a design so as to help the energy from the impact of transfer of shock from the surface into the material. By doing so, you prevent the internal components from getting damaged. A common cause of damage to any mechanical device is the G level it experiences. G level is determined by the drop height and rebound.

Hydraulic shock absorbers and their application

Hydraulic shock absorbers are equipments designed for the purpose of dampening rotator liner and other movement configuration. These hydraulic shock absorbers are used in a variety of applications like automobile, agricultural, aircrafts and many industrial applications as well. Large hydraulics is used in structural engineering’s like in buildings and industrial equipments.

Selection of a hydraulic absorber

In order to determine the right hydraulic shock absorber, one needs to understand the dynamic and static requirement of mechanical system. It is essential to know the energy input requirements to know the velocity of the shock absorb device for the shock absorbing device to wok accurately. One always needs to determine the following things before selecting the device.

·         velocity and stroke of the application

·         static and dynamic energy in a hydraulic shock absorber

·         installation and configuration of shock absorbers required

·         the kinetic energy

·         declaration of shock absorber size etc.
