Abstract

The invention provides a launcher of a pedestrian protection aPLI new leg type impactor. The launcher comprises a launcher body, an upper hook plate is arranged on the launcher body; a push plate is arranged in front of the launcher body; a shaft hole is formed in the gravity center of the launcher body; a connecting piece is fixedly arranged at the shaft hole; the launcher body is installed witha propeller of a pedestrian protection test system through a connecting piece. The upper end of the launcher body is in a concave shape, the upper hook plate is inserted into a gap of an upper body mass block of the aPLI new leg type impactor, thighs, knees and shanks of the aPLI new leg type impactor abut against the push plate, a clamping plate extending forwards is further arranged below the push plate, and the clamping plate can clamp the two sides of the shanks. A brand-new advanced leg type impactor aPLI testing function can be achieved, and all requirements for the leg type in the flight impact process in the standard are met.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, and in particular relates to a launcher for a pedestrian protection aPLI new leg impactor. Background technique [0002] Automobile pedestrian protection is one of the key projects that everyone pays attention to in the field of automobile safety. It mainly uses various impactors that simulate the human body to perform high-speed impacts and collide with the structure of the front end of the automobile to collect data for damage evaluation. The Global Technical Regulations on Pedestrian Protection began to adopt the flexible leg type (Flex-PLI) to replace the previous rigid leg type (TRL) in 2016. Changes on impact and damage, greatly improved accuracy. But in fact, the Flex-PLI leg shape still has obvious limitations. When a vehicle hits the human body, the human body moves in concert, and the upper part of the body has a significant impact on the lower limbs. Therefore, the impacto...
