“…Since double wishbone mechanism consists of the RSSR link and the SSP link (R: revolute, S: spherical, P: prismatic) [16], two independent complete circuits of EDFGE and ABCDE can be used for complex motion analysis. So as to gain the wheel alignment angle, the vector (e k → and e hub �� → ) in the simplified suspension curve in Figure 3 needs to be solved first [17,18]. So as to gain the vector e k → , the RSSR closedloop link composed of EDFGE should be considered first.…”

The work puts forward a way to research the kinematics of front double wishbone suspension by virtue of analytical method. A way of discussing the kinematics of rear five-link suspension is put forward by means of space coordinate transformation. The influence of suspension spring stiffness on the suspension characteristics is analyzed. The vehicle frequency response index is deduced in view of theoretical model of equivalent handling stability. The relationship between the vehicle frequency characteristic index and the frequency of the steering wheel angle under the variation of spring stiffness is gained, and the influence mechanism of spring stiffness on the vehicle frequency characteristics is explained. The suspension spring stiffness is the optimization variable, the vehicle frequency characteristic index is the optimization objective, and genetic algorithm is used to optimize the vehicle frequency characteristic.

“…[21] As the classical D-H parameter can be directly applied to the prismatic, cylindrical, revolute joints but it cannot directly applied to spherical pair so Jung-Fa-Hsieh (2010) introduces Extended D-H parameter method that can also applied to any spatial mechanism if it has spherical joints or not. For validation of this method they uses RSCP, CSSR, and CSSP mechanisms [22]. Haigang sun and Yong zohu (2010) is carried out design of RSSR mechanism by graphical method.…”

Abstract-spatial mechanism is a mechanical system that has at least one body that moves in a way that its point trajectories are general space curves. In many applications spatial mechanism has clear advantage on parallel mechanism and robots. RSSR mechanism is used in application like landing gear of JAGUAR Strike air craft, used in place of bevel gears between two shafts in the space. Many method such as iterative technique based on Newton-Raphson method, force fluctuation number, Graphical methods, methods using exponential matrices, screw theory, complex number theory, dual algebra ,D-H parameters, PRBM and other methods used for kinematic analysis of spatial mechanism. D-H parameters are used widely for kinematic synthesis because it assist ease for computer programming. In this paper critical review on this methods has been carried out. As D-H parameters method can directly applied to mechanism having joints like Prismatic, revolute, cylindrical and helical but it cannot directly applied to mechanism consisting spherical joints. Study shows that there is scope of kinematic analysis using extended D-H parameters, and most of the work focus on path generation so work can also done in velocity and acceleration analysis. Present study motivate researchers to work on presented research work.
