Vibration Transmissibility Analysis and Measurement of Automotive Clutch Spring Dampers

Dynamic analysis of automotive clutch dampers

The torsional dynamic characteristics of an automotive clutch are simulated by ®ve lumped parameter linear or nonlinear models. Each nonlinear model includes visco-elastic and dry friction elements. Dynamic sti€ness and energy dissipation spectra clearly show excitation amplitude and frequency dependent behavior. Also, dynamic hysteresis curves are predicted and analyzed. The proposed models co...

Measurement of hand-vibration transmissibility by non-contact measurement techniques

Background: Workers who use hand-held vibrating tools may experience finger blanching attacks due to episodic vasospasm in the digital vessels. In occupational medicine, the pathological consequences to the exposure to handtransmitted vibration are known as vibration induced white finger (VWF). In many cases, workers are recommended to use anti-vibration gloves and a standard procedure (ISO 108...

A biomechanical modeling of an automotive passenger body to investigate the vertical vibration in various road profiles using transmissibility analysis

In the current paper, a biomechanical model of human body with unique structure is developed for evaluating the biodynamic responses, the vibration transmissibility and the transmitted accelerations to vertical vibration for the seated position with ignoring backrest support. In this regard, the 6-DoF Lumped-parameter model with six concentrated masses which are connected with linear springs an...
