“…Design of kinematic suspension scheme is used to determine the position of the fasteners of the suspension elements (hardpoints) [1][2][3]. Furthermore geometric dimensions and position of the suspension hardpoints (calculated positions of joints and bushings centers) affect the K&C parameters of the suspension, which determine the handling, stability and patency of the vehicle [4][5][6][7][8][9][10][11][12]. Firstly, at the stage of designing a new chassis scheme, the required K&C parameters are laid.…”

This paper considers a modern approach of K&C parameters stability analysis using the suspension MBS model of a short-wheelbase electric vehicle. According to the results of the work, even minor errors in suspension hardpoints positioning when overlaying can greatly affect the K&C parameters of car suspensions. Using MBS models, quasi-static K&C events have been simulated. In the same way the dependences of the suspension K&C parameters are numerically determined. Moreover, these calculations were made with different hardpoints positions for joints of wishbones fastening on a frame, and joint of a steering rod with a steering rack. The influence of suspension hardpoints displacement on the K&C parameters of the vehicle was estimated. As a result, recommendations are made for production positioning tolerances of suspension hardpoints in order to avoid deterioration of K&C parameters. Basically, the appearance of inaccuracies in the positioning of hardpoints leads to critical changes in anti-dive, anti-lift, kingpin inclination angle, bump camber and bump steer parameters.

The suspension kinematics and compliance (hereafter referred to as 'K & C') characteristics as the important system assembly characteristics have a direct effect on the vehicle handling and stability performance and the ride comfort performance. The suspension K&C test rig is an key equipment to obtain the suspension K&C characteristics. Calculation method of the target parameters of K&C test-rig is studied. The movement law of the suspension K & C test rig is analyzed by useing the multi-body dynamics theory. Application Space rotation transformation matrix based on the measurement system structure is applied to solve the coordinates of the wheel center. Using the space vector operations and the definition of the toe angle and the camber angle, the solution method of the camber and toe angle is derived. The parralel wheel travel analysis using the multi-body dynamics model of the K&C test rig is taken. The simulation results when the rebound travel is-100mm is used to calculate the target parameters and verify the accuracy of the calculation method.Keywords-K&C test; calculation method; multi-body dynamics; rotation transformation matrix;
