Nowadays, electric and small cars are widely used in the world due to the reasons of optimal energy consumption, reduction of air pollution, congestion and heavy traffic. For this reason, it is necessary to use electric and small cars in the country. For this reason, an electric car has been designed, and in this research, the analysis and optimization of its dynamic sub-systems have been specially done. In this car, it should be noted that for the front suspension system, McPherson type and torsion beam type was chosen for the rear suspension system. Here, the analysis of this design has been done first, and then its optimization has been done in terms of ride quality and steering in a specialized manner and by examining the mechanisms. In this thesis, the analysis software of MSC company, namely ADAMS software, and its various modules, such as: ADAMS/CAR, ADAMS Insight, are used. Simulation of car dynamic model is done in ADAMS/CAR software and the process of test analysis, objective function modeling, analysis, execution and finally optimization is formed with ADAMS/Insight software. In the CAR module, various tests defined by the standards, such as parallel and opposite movement of the suspension system, controllability tests, double and single lane changes, forepost test, etc., are used. In the Insight module, the car has been optimized from the point of view of ride quality and controllability by performing a complete trial design and completing the optimization by connecting with the CAR part module. Model analysis and optimization is one of the innovations of this research.
