“…Vehicle suspension system is mainly composed of wishbone, spring, shock absorber to transmit and filter all forces between body and road. To satisfy these requirements, many types of suspension systems have currently considered, such as passive [2], semi-active [3], [4], active suspensions [5], [6]. It has been well known that active suspensions have a great potential in meeting the tight performance requirements demanded by users.…”

Abstract-This paper is concerned with the problem of fault detection filter for vehicle active suspension systems. The aim of this paper is to design a fault detection filter in finitefrequency domain. A sufficient condition for residual system with the prescribed H∞ performance index is derived based on the generalized Kalman-Yakubovich-Popov (KYP) lemma. In view of the obtained condition, the fault detection filter is designed in middle-frequency domain. Simulation results show the effectiveness and potential of the proposed results.Index Terms-Finite-frequency domain. Fault detection. Filter design. Vehicle active suspension systems.

“…Numerous papers about the theoretical and experimental investigation on the dynamic behavior of passively and actively suspended road vehicles have been published [1][2][3]. The quarter-car model [2][3][4][5][6], half-car model [7][8][9] and full-vehicle model [10][11][12] have been developed with researches related to the dynamic behavior of vehicle and its vibration control. The simplest representation of a ground vehicle is a quarter-car model with a spring and a damper connecting the body to a single wheel which is in turn connected to the ground via the tire spring.…”

Dynamic displacement and acceleration responses of cars with uncertain parameters under random road input excitations are investigated by using a quarter-car model. Based on the theory of random vibration, the vehicle's random displacement and acceleration responses are developed in time domain and frequency domain. The sprung mass, unsprung mass, suspension damping, suspension and tire stiffness are considered as random variables. The mean value, standard deviation and variation coefficient of the vehicle's natural frequencies and mode shapes are obtained by using the Monte-Carlo simulation method. The computational expressions for the numerical characteristics of the root mean square value of vehicle's random displacement and acceleration responses in the frequency domain are developed by means of the random variable's functional moment method and algebra synthesis method. The influences of the uncertainty of the vehicle's parameters on the vehicle's random responses are investigated in detail using a practical example, and some useful conclusions are obtained.

“…From the ground input, the reduction of transmitted force to the operator has been studied using passive, semi-active and active control methods including the works of Lee et al, 1 Vassal et al, 2 Kim et al 3 and Yagiz et al. 4 In the recent past, various control schemes using smart material such as electrorheological (ER) and magnetorheological (MR) fluid have been adopted for this purpose.…”

This paper presents the prototype shock reduction system (SRS) for the human supporting recoil mechanism device (HSRMD) subjected to impact force. Based on the parametric study of the HSRMD module, in order to reduce the force transmitted to the mounting body from the HSRMD, the passive and semi-active type shock reduction systems are studied. Parameters of the passive type SRS are determined by an optimization process under constrained conditions on the basis of the simplified HSRMD-SRS-human interaction model. The semi-active type SRS is devised using a MR damper with a feasible control scheme considering the disturbance characteristics. The performance of both systems is evaluated in a series of experiments using precisely constructed test setup. Finally, the transmitted force and linear impulse are estimated in the HSRMD-operator interaction condition for further developing process.
