description: This work is devoted to the study of the suspension system of the car, presented as a McPherson suspension on the front axle and a multi-link suspension on the rear axle. The tasks that were solved in the course of the research are as follows: 1. Analytical solution of the experimental problem to find the kinematic characteristics of the suspension using the displacement matrix method. 2. Step-by-step approach to get the optimal configurations of suspensions. 3. Sensitivity study of the obtained result to random changes in the positions of nodes at the car manufacturing stage. The work was conducted on the basis of LTD Compmechlab, where in the course of work on one of the company's projects the subject of this research work was formulated. MBD design of both types of suspensions is described. The principle and sequence of tests in the course of kinematic and compliance analysis of the car suspension was described. This was followed by formulating and solving a mathematical problem of finding the parameters of the McPherson suspension. After that the optimal schemes for the front and rear suspensions were obtained. As a result, the optimal coordinates of the investigated suspensions hard points were obtained. The following sensitivity analysis of the obtained optimal result showed that this suspension configuration is not stable, since there are several cases that prohibit even minimal deviations of nodes from their initial position. It is concluded that in order to identify less sensitive configurations, other pareto-optimal variants should be studied, if possible and necessary.
