Abstract This paper presents a novel approach in optimization of semi-active suspension system based on ride comfort and road handling characteristics. Semi-active suspension is capable of providing both ride comfort and road handling of the vehicle by optimization of various parameters. The model used for study is quarter car semi-active model. The entire analysis part of the paper has been carried out using Heat Transfer Search and Teaching-Learning based optimization algorithm. It also throws some light on comparison of semi-active and passive suspension based on their performance on similar road conditions by plotting graph of linear acceleration of sprung mass with respect to time.
