The aim of the course is to develop the vehicle layout design logic, as well as the design of its suspension and steering systems, based on specified requirements that the vehicle must meet. In addition, integrating and harmonizing the systems into a functional unit is a skill the student should master, while respecting relevant constraints regarding weight, dimensions, and ergonomics, as well as requirements related to comfort and driving capability. Gaining practical experience in computer-aided design, as well as evaluating various solutions, is an integral part of this process.

Upon successful completion of this course, students should be able to: • Identify all necessary requirements that the vehicle layout and its suspension and steering systems must fulfill during both the design and operational phases; • Analyze existing solutions for suspension and steering systems, as well as overall vehicle layout, in order to apply or modify them for a given vehicle; • Determine the suspension and steering system loads; • Apply the acquired design logic through the development of a vehicle layout and the aforementioned systems for a given design task; • Use modern engineering tools.

The lectures are divided into three main parts. The first part focuses on vehicle layout concepts, ergonomics, as well as legal regulations and recommendations related to this field. The second part is dedicated to suspension and steering systems, specifically the design of their components and the determination of parameters that define their kinematics and loading. The third part addresses the vehicle’s ride comfort, involving the design and selection of springs and dampers, as well as the calculation of their characteristics. Each part includes explanations of: • the initial requirements and parameters that form the basis for the design process; • the adoption of an appropriate layout; • the evaluation of existing solutions; • the identification, positioning, and dimensioning of the relevant system elements or assemblies; • the analysis of kinematics and the basic loads to which the structure is exposed.

Practical teaching consists of the development of an individual project for each of the aforementioned parts. In the course of project development, students have access to system, assembly, and vehicle models, while appropriate computer-aided tools are used.
