“…This is attributable to the suspension geometry, which is generally synthesized to achieve a compromise between variations in the roll and bump camber angles [26]. The observed asymmetry during the upward and downward wheel motions has also been widely reported in different kinematic responses [7,26,27]. This is also evident in the cumulative probability distribution of the absolute camber angle responses of the model with the three selected dampers in Fig.…”

“…The kineto-dynamic model presented in section 2 was further validated by comparing the camber angle and wheel centre lateral displacement responses of the model with those of a similar planar model developed in ADAMS/view platform. The comparison showed exact agreement between both model responses [7]. …”

“…The paper further investigates the synthesis of optimal parameters of a two-stage asymmetric damper to yield compromise between the conflicting performance measures under random road inputs at different velocities. Figure 1 illustrates the kineto-dynamic quarter-car model comprising a double wishbone type of suspension, employed to study the effects of damping asymmetry on the camber angle and vertical dynamic responses [7]. The model includes the contributions due to suspension kinematics and tyre lateral compliance as seen in Fig.…”

The influences of damper asymmetry on the camber angle variations of a double wishbone type of suspension, together with the dynamic responses under measured urban road inputs at different vehicle velocities, were investigated. Simulation studies employing a kineto-dynamic quarter-car model comprising a bilinear damper revealed complex dependence of the dynamic and kinematic responses on the vehicle forward velocity. The study further revealed an increase in camber angle variations with an increase in damper asymmetry, while this increment showed a non-linear relationship with the suspension deflection. The camber angle variation under road inputs thus poses an additional design compromise apart from those associated with the well-established conflicting measures of ride comfort, rattle space, and road-holding properties. The study also investigated the synthesis of an optimal two-stage asymmetric damper to yield a compromise between these conflicting performance measures under road inputs at different vehicle forward velocities with consideration of minimal camber angle variations. A composite performance index, comprising the ride comfort and road-holding measures with limit constraint on camber angle variation, was formulated to seek optimal damper parameters. The results showed that an optimal asymmetric damper could be identified to yield acceptable design compromise over a wide speed range.

In this study, a novel kinematic analysis procedure of the double wishbone suspension mechanism regarding steering input is proposed. In the previous study, published by the authors, the double wishbone mechanism was investigated disregarding steering input. To the best of our knowledge, there is no analytical method available in the literature for the analysis of double wishbone suspension mechanism regarding steering input. Initially, analysis of the mechanism for variable steering input, while keeping wheel travel fixed is considered. Then, kinematic analysis is performed analytically for the ultimate case of two inputs. Analysis simultaneously for both variable steering and variable wheel travel is presented. The essential parameters; camber, caster, kingpin angles are defined according to the kinematic model. For verification, a synthesized mechanism is established in Catia software and same results with the analytical model are obtained. Another presented novel analytical approach is anti-dive/lift analysis of the double wishbone mechanism.

This paper introduces novel approaches for analysis of the double wishbone suspension mechanism. In the literature, to the best of our knowledge there is no analysis study available for the double wishbone mechanis m that is performed "analyt ically". Init ially kinematic model of the double wishbone mechanis m is established. Then, a kinematic analysis methodology is presented. This analysis procedure is carried out analytically. The essential parameters; camber, caster, kingpin, toe angles, and track variat ion are defined according to the kinemat ic model. A double wishbone suspension mechanis m is synthesized as an examp le by using the method presented in this study. Variat ions of the essential parameters with respect to wheel travel are plotted. The synthesized mechanis m is established both in Lotus Suspension Analysis and Catia software and same results with the analytical model are obtained. Thus, it is verified that mechanisms of different dimensions c an be analyzed and parameters can be optimized precisely and swiftly by using this analytical approach.
