Definitions
- Test device for carrying out examinations on a test body
- the invention relates to a test device for carrying out tests on a test body, comprising a rail guide with a slide unit coupled to a drive unit for acceleration on which the test body is arranged, wherein the drive unit is connected to a control unit and at least one image acquisition unit for acquiring image data of the Test body is provided
- a device for examining a test body has a receiving unit for fixed arrangement of
- an electric drive unit for driving the receiving unit with the test body and a control unit for controlling the electric drive unit for accelerating the arranged on the receiving unit test body.
- the device is designed such that the
- Receiving unit and the test body located thereon are mechanically driven only by means of the electric drive unit, wherein the electric drive unit comprises a linear electric motor. Furthermore, the device has an analysis unit, which has a camera for capturing images or videos for subsequent evaluation.
- the invention has for its object to provide a comparison with the prior art improved test apparatus for performing studies on a test body.
- a test apparatus for carrying out examinations on a test body comprises a rail guide with a slide unit coupled to a drive unit for acceleration, on which the test body is arranged, wherein the drive unit is connected to a control unit and at least one
- Imaging unit is provided for detecting image data of the test body.
- the at least one image acquisition unit is at another
- Carriage unit of the test body extending further rail guide is arranged, wherein the further slide unit of the at least one image acquisition unit has a separate drive unit connected to the control unit for accelerating the further slide unit.
- the at least one image acquisition unit is arranged on the further slide unit, which can be driven by means of the separate drive unit, it is possible in a particularly advantageous manner to have a weight on the slide for accelerating the test body by the weight of one known from the prior art moving rack on which the image capture unit is attached to reduce.
- a weight on the slide for accelerating the test body by the weight of one known from the prior art moving rack on which the image capture unit is attached to reduce.
- Fig. 1 shows schematically a perspective view of a testing device according to the
- Fig. 2 shows a perspective view of a separate camera slide
- Fig. 3 shows a schematic perspective view of the test apparatus with the
- FIG. 1 shows a test device for carrying out tests on a test object according to the prior art, not shown in more detail.
- the testing device comprises a rail guide 1, a carriage unit 2 arranged on the same, which is coupled to a drive unit, not shown.
- the carriage unit 2 is movable on the rail guide 1, wherein the carriage unit 2 by means of the drive unit can be accelerated and braked.
- the drive unit is connected to a control unit, whose generated control signals can be supplied to the drive unit, so that the slide unit 2 is accelerated or decelerated.
- a frame 3 is laterally arranged and fixed, wherein on the respective frame 3, two image capture units 4 are attached.
- Such a test apparatus is provided for collision simulation of a vehicle body, wherein the test body arranged on the carriage unit 2 is a vehicle body with at least one crash test dummy which represents a dummy of a vehicle occupant.
- the test body can be accelerated with an inverse crash pulse in order to simulate the same procedure for vehicle occupants in the event of a collision of a vehicle.
- the movement of the at least one crash test dummy resulting from the simulation of the crash pulse can be detected by means of the image acquisition units 4, which are designed as high-speed video cameras.
- the racks 3 are arranged and fixed on the carriage unit 2, so that the image capturing units 4 move with the carriage unit 2.
- These racks 3 have a weight, which in addition to the weight of the carriage unit 2 and the test body must be accelerated, so that it is at least partially not possible to simulate specific vehicle crash pulses due to the thus relatively high total weight. In other words, a performance of the test apparatus for the high mass to be accelerated is insufficient.
- Rail guide 5 is provided for the image acquisition units 4.
- a section of the further rail guide 5 is in Figure 2 and the entire
- Test device with the other rail guide 5 is shown in Figure 3.
- Figure 2 shows a perspective view of the further rail guide 5 for a further slide unit 6, on which an image detection unit 4 is arranged.
- the further slide unit 6 serves as a carrier of the image detection unit 4 and is coupled with a separate drive unit 7 for acceleration thereof.
- This separate drive unit 7 is an electromagnetic drive.
- the further rail guide 5 is parallel to the
- Rail guide 1 of the test body arranged, which can be achieved that the test body and the image detection unit 4 are at a same level and corresponding image data can be detected.
- a sampling of a signal on the carriage unit 2 with the test body arranged thereon preferably takes place via a high-resolution incremental encoder and / or laser.
- a predetermined simulated crash pulse in digital form, that is, in data form, in a control software of the further carriage unit 6.
- the control software of the further carriage unit 6 is then supplied with a triggering signal from the control software for accelerating the carriage unit 2 of the test body for synchronization.
- two further rail guides 5 are provided, each with a further slide unit 6, a further rail guide 5 is arranged parallel to the rail guide 1 of the slide unit 2 of the test body, so that the rail guide 1 of the test body between the two further rail guides. 5 for the image capture units 4 is located.
