A Predicting and Improvement of Side Impact Using the CC-CTP

Extensive researches are being performed on a world wide basis with the aim of enhancing occupant protection on the side impact. The test methodology for side impact can be divided into two general groups;

• Sub-System Tests
• Full Scale Tests.

However, the advantages of full scale test is that it is possible to make an integrated statement on the protective potential of the structural stiffness of the struck vehicle and the padding for a selected collision speed and type of collision. The advantages of sub-system test methodology can be simulates more exactly for wide range of accident(i.e. collision directions, impact points etc.). The latter test procedure can be carried out at a relatively earlier stage in the development of a new vehicle, and also can be reduce the time and cost.

The Computer Controlled Composite Test Procedure(CC-CTP) presented in this paper has been developed by CCMC (Committee of Common Market Automobile Constructors). It is attempt to combine the advantages of sub-system and full scale tests. The exterior deformable moving ram and interior body rams of the CC-CTP test system are controlled by a computer system. Then the full scale test is simulated by computer calculation. In this paper, the results of CC-CTP tests are compared with those of full scale tests. The various occupant protection methods are described and compared with CC-CTP and full scale tests. Door component test procedure in conjunction with CC-CTP can be performed at a relatively early stage and these are utilized to present a set of useful tools which will enable the user to enhanced the side impact protection.
