The dynamic model of the front double wishbone suspension and the rear multi-link suspension of the vehicle are established. On the basis of detailed analysis of suspension kinematics, calculation method of wheel alignment angle and force calculation of suspension bushing, the influence mechanism of suspension bushing on the vehicle transient state is clarified, and the vehicle transient characteristic index is derived from the vehicle three-free dynamic model. The sensitivity analysis of the suspension bushing is carried out, and the bushing stiffness which has a great influence on the transient state of the vehicle is obtained. The bushing stiffness scale factor is used as the optimization variable, the vehicle transient characteristic index is used as the optimization target, and the NSGA-II optimization algorithm is used for multi-objective optimization. After optimization, one Pareto solution is selected to compare with the original vehicle, the comparison results show that the yaw rate gain, resonance frequency and delay time of yaw rate in the vehicle transient characteristic index are all improved, other optimization targets change less. In the steady-state comparison, the understeer tendency of the vehicle increases, and the roll angle of the vehicle increases but is within an acceptable range.

Mechanism is an intended to turn input motion into a required set of output motion and forces. Now a days the spatial mechanism is widely used in various industrial applications like parallel kinematic machines as a robot manipulator. The main aim of the review paper is to use the Jacobian matrix into the kinematic analysis. From the review papers analysis, it has been concluded that the Kinematic analysiswith help of Jacobian matrix performed various Multi-loop Spatial Mechanism settings for Kinematic geometry, its topology and to carried out displacement modelling. It also used to Kinematic Design, synthesis and optimization. Finally, Comparison of existing methods for Kinematic Singularities with Jacobian in Parallel Manipulator.

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.
