Course detail

Virtual Prototypes

FSI-QVPAcad. year: 2018/2019

Virtual prototypes significantly reduce the time for motor vehicles development. Prototypes enable to prove and optimize vehicle properties before a real prototype is made . Engineers mastering this area are demanded on the labour market. 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.

Learning outcomes of the course unit

Students will have a clear idea of which problems are possible to solve with the multi-body software, what data are necessary, what outputs we are able to get. Students will learn how to build virtual prototypes by themselves.

Prerequisites

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

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 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.

Aims

The aim of the course is to make students familiar with theoretical and practical knowledge of virtual prototypes. They will learn of multi-body software and its development trends.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars is obligatory, checked by a teacher. The way of compensation of absence is solved individually with a course provider.
