PROSPECTIVE ELECTROMECHANICAL SHOCK ABSORBERS

Electromagnetic Shock Absorbers

Automobiles and trucks have shock absorbers to damp out the vibration experienced due to roughness of the roads. However, energy in conventional shock absorbers gets dissipated as heat and not used in any way. Regenerative electromagnetic shock absorbers provide means for recovering the energy dissipated in shock absorbers. Electromagnetic shock absorbers for potential use in vehicles are fabri...

Turtle shells have built-in shock absorbers.

Singing karaokemakes most of us quickly realize how poorly we can carry a tune. Typically, when we’re confident enough to sing on stage, we’re deaf to the negative feedback. Recently, however, neuroscientist Jesse Goldberg at Cornell University, USA, discovered a brain region that listens and produces a chemical ‘booing’ when birds sing off key. Vikram Gadagkar and colleagues in the Goldberg la...

Measurement of Equivalent Stiffness and Damping of Shock Absorbers

This paper describes a new testing and analysis methodology for obtaining equivalent linear stiffness and damping of automotive shock absorbers for use in system-level chassis and vehicle computer aided engineering (CAE) models for noise and vibration prediction. Since most of the system-level CAE models in a vehicle are linear in nature, equivalent linear parameters of chassis components are m...

The Use of Amplitude Measurement in the Diagnosis of Hydraulic Shock Absorbers of Passenger Cars

The article presents the amplitude measurement used in the diagnosis of hydraulic fluid leakage from the shock absorbers of passenger cars. Measures used to assess the distribution of the peak using the free vibration method with force extortion. To verify the results of study the FFT were used. In particular illustration of a random vibroacoustic process, acceleration of sprung mass for front ...
