Modeling and experiment of vehicle double-tube hydraulic shock absorber

2011 International Conference on Electric Information and Control Engineering, 2011
In order to solve the problem of predicting damping characteristic of the shock absorber in the stage of design, a mathematical model for the shock absorber was built and simulated using the software Easy5. The establishment of the model was based on the analysis of internal configuration and working principle of double-tube hydraulic shock absorber ...

Nonlinear vibrations of hydraulic shock absorbers

Journal of Engineering Physics and Thermophysics, 2008
A method of equivalent linearization for a nonlinear dynamic system of vibrations with a hydraulically elastic shock absorber is presented. An integral estimation of the exact and approximate solutions is obtained. It is shown that with an appropriate choice of the parameter λ the linearized dynamic system differs insignificantly from the nonlinear one.

Nonnatural vibrations of hydraulic shock-absorbers

Journal of Engineering Physics and Thermophysics, 2008
Based on the procedure developed by the present authors, calculation of a construction unit intended for reducing high levels of vibrations has been carried out. The corresponding physical characteristics of the unit elements have been selected. For a multi-element model, an equivalent of a change-over to a single-mass vibrational system has been found.

Performance Simulation of Hydraulic Energy-Regenerative Shock Absorber

Advanced Materials Research, 2013
This paper presents several kinds of energy-regenerative shock absorbers, which all exist some problems. Then, we put forward a novel type of shock absorber: Hydraulic Energy-regenerative Shock Absorber (HESA). In this paper, we focus on damping characteristic and energy recovery of HESA.
