Course detail

Simulation and Testing of Products

FSI-HSI-KAcad. year: 2024/2025

The course is focused on the field of the product design verification made with computer simulations and physical testing of the product samples. The most commonly used types of simulations and tests (vibrations, thermal management, kinematics, manufacturing technology, lighting characteristics, electronics) will be presented in detail with using of tolerance analyses and simulations in the headlight development (tolerance types and tolerance chains for optical elements and plastic materials), calculation methods of tolerances and their specific applications in tolerance analyses and simulations. The follow-up area is prototyping, where the students learn to involve the prototype workshop into a real process of development headlight and back group lamps in the automotive industry, including the production of prototype optical members. Students will become familiar with the used prototype technologies of individual component and the subsequent surface finish. The samples of components are by optical scanning systems included retroactively into the analyses and related validation of parts.

Entry knowledge

A basic knowledge of polymers and their mechanical properties, CAD and CAE technologies. Technological characteristics of the machining methods.

Rules for evaluation and completion of the course

Completion of the course: graded credit
Student requirements: attendance + seminar work elaborated individually or in a team (according to the number of registered students)

All of exercise lesson are obligatory. The student’s own work and knowledge is assessed in practicals. According to the studied topic some lessons will be practicals - carried out in the lab, and some will be focused on the theory - calculations carried out in the classroom in a seminar form. Absence from seminars should be substituted for by attending a seminar with another study group or individually by the agreement with the teacher. Lessons may be occasionally inspected by the head of the department.

Aims

The course provides the students a practical knowledge about the phase of product certification for automotive industry. The graduate should be able to select effectively the required tools of CAE simulation and physical testing when validating of a proposal to shorten the development cycle and preventing problems in using the product by customer. The related area of product validation is prototyping while taking into account the current technological possibilities including the specifics of thick-walled optical polycarbonates and other reflective systems and solving the specific examples of prototyping. The practical examples demonstrate the suitability of the used prototype technology for obtaining the desired properties of individual parts of the headlights. The follow-up area is using of tolerance analyses and simulations to verify or to optimize the dimensions of individual components and sub-assemblies in the development stage of headlights, including verification of products while using 3D scanning systems GOM (one of the most advanced optical systems in automotive industry).
Students are trained in practical knowledge of the application of CAE simulations, prototyping with technology of prototype optical elements (additive technology, vacuum casting, plastic moulding, precision CNC machining), with following surface treatment according to contemporary standards, technology of 3D scanning of components and re-use of scanned data for a product validation.
