Description

Technical Field

[0001] The present invention relates to a passenger car component collision test platform, and more specifically, to a passenger car component collision test measurement platform system and method. Background Art

[0002] In major universities and research institutes, there has been little development of quantifiable component collision test measurement and analysis platforms for passenger car component collision test measurement platforms.

[0003] The existing component collision test measurement and analysis platform can mainly measure two sets of data: unidirectional force and displacement. The force value is mainly obtained by sticking strain gauges on the components. Its disadvantages are large measurement limitations, no repeatability, poor operation convenience, high cost, and occupying many signal channels. The displacement is mainly obtained by adding marking points to obtain the value of the component after the collision through high-speed camera. Its disadvantages are that the optical device lens is prone to distortion, poor accuracy, long calculation time, and low efficiency.

[0004] Passenger car parts are subjected to destructive collision tests through the collision test platform system, which can qualitatively and intuitively test the damage status of parts. However, there is still a lack of component collision test measurement systems that can provide accurate collision test data such as time, vibration three-dimensional acceleration, three-dimensional force, displacement, speed, energy, etc.

[0005] In existing patent applications, for example, publication number CN101865757A discloses a pneumatic piston automobile parts collision tester. In the technical solution disclosed in the patent document, a pneumatic piston automobile parts collision tester is disclosed, but the composition of the collision machine measurement platform system is not involved.

[0006] For another example, publication number CN101865756A discloses an electric vehicle component collision test machine. In the technical solution disclosed in the patent document, an electric vehicle component collision test machine is disclosed, but the composition of the collision machine measurement platform system is not involved.

[0049] Collision mechanism, used to collide with passenger car parts;

[0050] The data analysis organization establishes a data connection with the collision organization to obtain various data generated when the collision organization collides with passenger vehicle parts.

[0057] The automatic ejection mechanism 7 is arranged on the travel track 8. When the collision vehicle 3 travels to the position of the automatic ejection mechanism 7, the collision vehicle 3 is released by the automatic ejection mechanism 7 to complete the collision test between the collision vehicle 3 and the passenger vehicle parts.

[0058] The data analysis mechanism includes a transmission cable 9 , a column 10 , a dynamic data analyzer 11 and an industrial computer 12 .

[0059] One end of the transmission cable 9 is connected to the vibration three-axis acceleration sensor 5 , and the other end is connected to the dynamic data analyzer 11 .

[0060] There are a plurality of upright posts 10 , which are arranged in parallel on one side of the travel track 8 to form a transmission cable track 13 for moving the transmission cable 9 .

[0061] A network communication is established between the dynamic data analyzer 11 and the industrial computer 12 .

[0065] The height of the installed transmission cable track 13 must be kept consistent to ensure that it is on the same horizontal plane.

Adjust the collision position between the collision head 4 and the passenger car parts. After the motor traction mechanism trolley 6 is connected to the collision trolley 3 with the vibration three-axis acceleration sensor 5, it is dragged and parked at the initial end of the driving track 8. Open the dynamic data analyzer 11, read the information of the collected data, set the parameters of the collected data, and perform signal balance and zeroing operations (see Figure 2 shown).

[0075] At the beginning of the test, in order to ensure the accuracy of the measurement, the speed of the collision car 3 is set to 15km / h, and the industrial computer 12 is started to obtain data instructions. After receiving the sampling command, the dynamic data analyzer 11 takes data and transmits it to the upper-level industrial computer 12; all sampled data are transmitted to the industrial computer 12 in real time through the network for analysis, display processing and network data distribution (see Figure 3 shown).
