Description
Technical Field
The invention belongs to the technical field of automobile testing, and particularly relates to a launcher of a pedestrian protection aPLI new leg type impactor.
Background
Automobile pedestrian protection is one of key items which are concerned by people in the field of automobile safety, and mainly carries out high-speed impact collision on the collected data of the front end structure of an automobile by simulating various impactors of a human body to carry out injury value evaluation. The pedestrian protection global technical regulation adopts a flexible leg type (Flex-PLI) to replace a previous rigid leg Type (TRL) from 2016, the Flex-PLI leg type respectively reflects the change of a human leg when the human leg is impacted and the injury condition from three parts of a femur, a knee joint and a tibia, and the accuracy is greatly improved. In practice, however, the Flex-PLI leg type still has significant limitations. When a vehicle impacts a human body, the human body moves in a coordinated manner, and the upper part of the body has obvious influence on the lower limbs, so that the impact of the upper part of the body on the lower limbs is considered during design of the impactor, and the risk assessment on leg injury can be better performed. Currently, ISO introduced a new test tool, aPLI (advanced pedestrian leg impactor), merging upper and lower leg shapes. Under the same test condition, the bending moment of the bone and the elongation of the ligament are increased in different degrees, so that the lower limb injury value is reflected more truly and accurately.
In the pedestrian protection test Program of the European New Car evaluation protocol (Euro-NCAP for short hereinafter), the leg test section has determined the selection of aPLI as a New leg impactor. Since aPLI is not widely used in China, and the launcher of the impactor is designed and debugged in a Flex-PLI leg type, a new launcher matching aPLI needs to be developed by self. Against this background, an impactor launcher adapted to the aPLI leg type is imminent.
