Course detail

Virtual Prototypes

FSI-QVP Acad. year: 2024/2025 Summer semester

Virtual prototypes significantly reduce the time for motor vehicles development. Prototypes enable to prove and optimize vehicle properties before a real prototype is made . Students in this course will be made familiar with theoretical but also practical knowledge in this field. Software ADAMS was chosen for the practical part of the course, as it is one of the most widely used software for vehicle dynamics analysis.

Entry knowledge

Matrix calculus. Basic knowledge of numerical mathematics and technical mechanics, kinematics, dynamics.

Rules for evaluation and completion of the course

The course-unit credit requirements:
Mastering fundaments of lectured problems and practical realizations of computations using computer technology and software tools, knowledge applying is examined on assigned problems, individual elaboration of the assigned tasks without fundamental deficits. Continuous evaluation is made at seminars.
Examination:
Examination is based on evaluation of knowledge of fundamental problems, ways of solutions and its applications in exercises.
The exam consists of a written part (test) and an oral part. Final evaluation consists of: 1. Evaluation of the work on seminars (elaborated tasks). 2. Result of the writing part of the exam (test). 3. Result of the oral part of the exam.
Attendance at seminars is obligatory, checked by a teacher. The way of compensation of absence is solved individually with a course provider.

Aims

The aim of the course is to make students familiar with theoretical and practical knowledge of multi-body software. They will learn of multi-body software and its development trends.
Students will have a clear idea of which problems are possible to solve with the multi-body software, what data are necessary, what outputs they are able to get. Students will also acquire the necessary knowledge to enable them to independently create multi-body models using software tools.
