Search engine "Test with two or more (deformable) objects [non EES]"
Crashtest-service.com GmbH provides a search engine to find crash tests that are available in the database. The search engine has been optimised for Microsoft Internet Explorer Version 5.5 or higher.
Under the "Test with two or more (deformable) objects [non EES]" heading you will find all collision tests in the database with two collision partners like dummies, two-wheeled vehicles and twin track vehicles and also with special collision partners. Tests carried out to determine the absorbed deformation energy (EES) you will find at "Impact into a non deformable barrier [EES].
In order to find the required test you must first select the two collision partners. This is done via pull-down menus. You can make subsequent changes to your selection at any time. In principle the sequence of the selected collision partners is not decisive for the search. In other words, you would get the same results by entering "motorbike" against "car" or "car" against "motorbike".
When you have made your selection the first query is made to the test database. A preliminary selection is made as to whether tests are available with the selected collision partners. If no tests exist with these collision partners, the following error message is displayed:
In this case, please change your selection.
If the query shows that no tests with the collision partners selected at B are available in the database but that tests with collision partner A do exist, the system considers all available collision partners B associated with the selected collision partner A in the subsequent search process.
If the query result contains less than ten tests, the tests are displayed in a list with preview pictures and the main test data and any special features that may exist. If more than ten tests are available for the selected collision partner combination, the search engine first offers further selection criteria. The search can then be more detailed on the basis of these extra parameters. However, you can chose not to select all or any of the criteria.
When selecting further selection criteria the order of entry is significant, as the selected parameters are allocated to collision partner A or collision partner B respectively. By definition, collision partner A is the vehicle whose speed vector is directed towards the other vehicle. Consequently, as a rule the striking (impacting) vehicle is described as collision partner A and the struck (impacted) vehicle as collision partner B. For example, in a rear-end collision the vehicle that drives into the other vehicle is collision partner A and the vehicle in front is collision partner B. However, if a vehicle reverses and its rear end crashes into the front of a vehicle behind it the reversing vehicle is collision partner A and the vehicle whose front is damaged is collision partner B. Consequently, the entries collision partner A: car, impact zone: front and collision partner B: car, impact zone rear end provide different results from the entries collision partner A: car, impact zone: rear end and collision partner B: car, impact zone front.
First, the impact zone for each vehicle must be defined. The next step is to specify the range of the angle of collision. The definition of the collision angle can be taken from the sketch above the pull-down menu connected with the selection. For example, in the case of a pure rear end collision the angle is 0° and in the case of a frontal collision the angle is 180°. In the case of reversing vehicles the direction of movement is important for the definition of the angle, not for the front/rear end direction of the vehicle.
You can also limit the degree of overlap of the vehicles and the height of impact. From a practical point of view these criteria mainly relate to rear end and frontal collisions. The degree of overlap describes the ratio of the vehicle width to its contact surfaces and is given as a percentage. The height of impact states whether the bumper of the impacting vehicle hits the bumper of the other vehicle or if it hits the vehicle above or below the bumper (under- or overriding).
Finally, for each collision partner you can select a collision speed range. A collision speed of 0 km/h corresponds to a standing vehicle.
At the end of the form the query can be submitted to the database via "Evaluate". When you click the underlined collision partner description of the listed tests the system displays the associated details.
In addition to the details the test sheets available for the test are listed along with the prices of the sheets. In the visitor access the prices include value added tax. For registered users the test costs are shown without value added tax.
The test sheets are bundled into packages. The basic bundle contains all essential test documentation such as photos of the collision configuration, of the vehicles before and after the crash, measured values etc.. If available we also offer packages with grabbed video sequence images of the vehicles and the passengers from various perspectives as well as measurement diagrams and a sketch of the final positions of the vehicles with the respective measurements etc. In the visitor access area you will find examples of the test documentation available for download.
