1. Introduction

This course work serves to consolidate and systematize the knowledge obtained during the study of the discipline "Design and Calculation of Cars."

According to the received terms of reference, it is necessary to calculate the design parameters and operational parameters of the car. The results of the calculations should be as close as possible to the prototype.

The course work consists of two parts: an explanatory note and a graphic part. The graphic part consists of four drawings of A3 format:

- general view drawing of the ATS prototype;

- drawing of external speed characteristic graph;

- power balance diagram drawing;

- Dynamic car passport drawing.

Conclusion

As a result of this course work, a calculation was made, in accordance with the requirement of the technical specification, design parameters and performance indicators of the car. These parameters have only minor deviations from the parameters of the selected Lexus Lx 570 AWD prototype.

Thanks to this course work, I consolidated and systematized the knowledge gained in the study of the discipline "Design and Calculation of Cars"
