Test device for pedestrian head impact

Abstract

The invention discloses a test device for pedestrian head impact. The device comprises a launching rack, a launching mechanism and an angle adjusting mechanism; the launching rack is provided with a mounting bottom plate; the launching mechanism is arranged on the mounting bottom plate and can rotate relative to the mounting bottom plate; one end of the angle adjusting mechanism is fastened to thelaunching rack, and the other opposite end of the angle adjusting mechanism is fastened to the end, opposite to the launching end, of the launching mechanism; the launching mechanism comprises a thrust air cylinder assembly, an energy storage assembly connected with the thrust air cylinder assembly, a release air cylinder assembly connected with the energy storage assembly, a launching frame connected with the energy storage assembly and a head impactor, wherein the head impactor is installed on the launching frame. By means of the test device for pedestrian head impact, the protection performance of an engine hood for pedestrian head impact can be verified in advance in the design process of the engine hood, and therefore, a development period is shortened; pedestrian head impact tests can be simulated for various vehicle types, the development cost is reduced, and therefore, the application range of the device is wide.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a test device for pedestrian head impact. Background technique [0002] With the rapid growth of car ownership, increasingly complex road conditions and frequent car traffic accidents, pedestrian head injuries account for more than 30% of pedestrian-vehicle collision injuries; and head injuries account for more than 30% of pedestrian deaths. more than 60%. The protection of pedestrians outside the vehicle is the focus and priority direction of China's current automobile safety work. [0003] Currently, in the development process of pedestrian protection head-impact performance, it is necessary to carry out a head-shaped impact test to verify the pedestrian protection head-impact performance of the vehicle. In the touch test, there are problems such as additional mold design change costs due to substandard performance in the later stage of the test, long test period, and ...
