What is the function of an automotive damper?
1 Answers
Automotive dampers function by providing resistance to motion and dissipating kinetic energy. Definition of a damper: A damper is a device designed to provide resistance to motion and dissipate kinetic energy. Various types of dampers (or shock absorbers) have long been utilized in industries such as aerospace, aviation, military, firearms, and automotive to mitigate vibrations and absorb energy. Since the 1970s, these technologies have gradually been adapted for use in structural engineering applications including buildings, bridges, and railways, with rapid development. Notably, the hydraulic viscous damper, with over fifty years of history, underwent extensive testing, rigorous review, repeated verification, and particularly a prolonged process of seismic validation before being accepted by the structural engineering community in the United States. Overview of dampers: Dampers, also known as damping devices, are engineered to rapidly attenuate vibrations induced by impacts through increased damping. Ideal dampers include oil dampers, which commonly utilize oils such as silicone oil, castor oil, machine oil, diesel, engine oil, and transformer oil. These can be designed in various forms including plate-type, piston-type, square cone, and cone shapes. Other types include solid viscous dampers, air dampers, and friction dampers. For practical vibration isolation design needs, an optimal damping ratio D ranges between 0.05 and 0.2.
