Computer Mechanical Study Types
TRANSPOLIS can accompany its clients' R&D process by conducting different types of numerical studies : development of new systems, modifications of existing systems, optimization studies, accident reconstruction.
Development of new systems
We can consider new safety system designs proposed by our clients. The numerical model is developed and evaluated in different impact configurations. The performances can be compared with other designs of the same client, already tested of computed. That kind of studies generally lead to optimization studies.
Study packages can be offered from predefined conditions agreed with the client.
Modifications of existing systems
A manufacturer may sometimes modify a component of an existing protection system. In that case, the numerical study will consist in the evaluation of the effects of this proposed modification on the system performances. When an experimental crash test has been previously performed with the basic system, the evaluation of the modification is done by comparing with the validated simulation of this basic system.
In most of the cases, we have to perform in-depth analysis of the effect of numerous technical parameters and so we can help to the performance optimization of the systems.
These analysis can be done on geometric parameters, on material characteristics, on different type of component links,...always taking into account the economical aspects resulting from the system manufacturing.
Development of simplified and customised models
In addition to vehicle and road-furniture testing, our numerical tools also allow the use of numerical dummies to assess impact injury criteria (head, neck, chest, etc...); they can be used for example in preventive studies for motorcyclists, or to model parts of the human body for specific applications, such as orthopaedic implants.
This biomechanical expertise is put to great use for the GHBMC project that aims to draw up a numerical model of the human body.
