Simmulation in Automotive Industry (FSI-QPA)

The objective of the course is to familiarize students with contemporary computational models that are applied for solving various types of problems in the development of motor vehicles. The computational models are used to simulate linear and non-linear structural mechanics problems using the finite element method. This includes an introduction to the mathematical and physical nature of computational models and the presentation of these models through software tools.

The course will enable students to gain knowledge of contemporary computational models applied to structural mechanics of powertrains and motor vehicles. The acquired skills will enable students to perform analyses of strength of mechanical structures, heat conduction in solids, large deformations, body contacts or fast dynamic processes.

Knowledge of mathematics taught at the bachelor’s degree level and necessarily includes linear algebra (matrices, determinants, systems of linear equations etc.), differential and integral calculus and ordinary differential equations.
Knowledge of basic kinematics, dynamics and strength of materials.

The course is intended to introduce students to the most important contemporary computational models applied in the development of modern powertrains and motor vehicles. Emphasis is placed on the mathematical and physical basics of computational models and software tools, as well as the verification of computational modelling results by adequate experimental methods. The presented problematics includes applications of the finite element method in the analysis of deformation, stress, fatigue safety, temperature or contacts of motor vehicle components.

The course-unit credit is conditioned by active participation in the seminars, proper preparation of the semester work, and fulfillment of the conditions of the control tests. The exam verifies the knowledge gained during lectures and seminars and is divided into a written theoretical part, part of the computational solution of lubrication, fluid flow and heat transfer, and an oral part. The exam considers the work of the student in the exercise. The student must score more than one-half of the total points for the successful completion of the test. An oral examination can test the student's knowledge of the subject and influence the final grade.

Exercises are compulsory, and the form of replacing the missed lessons is solved individually by the lecturer or with the course guarantor. Lectures are optional but strongly recommended.
