Numerical Modeling of Vibratory Motion of Shock Absorber Performance in Automobiles
Abel Kurura Tinega [3] | Omariba Geofrey Ong'era
Abstract: Vibration is essentially an oscillatory motion. There is a force that initiates the vibratory motion. The research involves improving the shock absorber by using variable external disturbance force, spring and damper to come up with variable shock absorber model which adjusts depending on the shock. Using MATLAB software, a response of the system to a harmonic disturbance of variable automobile weight and to an impulse excitation is found. The objectives of the study are to determine the effects of both the distribution of spring - supported automobile weights and the shock absorber thickness on vibrations of the mounting points of the shock absorber. The equation governing vibratory motion of shock absorber is solved using Finite difference method with central difference scheme. The effects of both the distribution of spring - supported automotive weights and the shock absorber thickness on vibration are discussed and presented graphically. Various values of automobiles weights and thickness are used in the study. The findings obtained reveal that, an increase in automobiles weights leads to an increase in the impulse excitation of the shock absorber. It was also found that an increase in shock absorber thickness leads to a decrease in vibrations motion. The study provides insight knowledge which is important in elimination of vibrations in automobiles in order to improve both the comfort and the safety of the passengers.
