Course detail
Simmulation in Automotive Industry
FSI-QPA Acad. year: 2022/2023 Winter semester
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.

Learning outcomes of the course unit
Learning outcomes of the course unit The course Simulation in Automotive Industry enables students to gain knowledge of contemporary computational models applied in the design of power units and vehicles, dynamic and strength analysis of mechanical structures and in solving problems in the field of heat conduction and acoustics.
Prerequisites
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.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline.
Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
The course-unit credit is conditioned by active participation in the seminars, proper preparation of the semester work and fulfilment 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 and oral part. The exam considers the work of the student in the exercise. The student must score more than one half of points for the successful completion of the test.
Aims
The objective of the course is to male students familiar with actual computational models applied for solving various types of tasks related to powertrain and motor vehicles development. The aim of the course is to explain students mathematical and physical fundamentals of computational models, which are very often built up to ready-to-use software level.
