The invention relates to a sped adjustable automobile side crash device and an experiment method, belonging to the technical field of automobile safe performance test. The device comprises a rotating shaft (3) which is sleeved with an auxiliary pendulum bearing sleeve (2), one end of an auxiliary pendulum (7) is fixed on the auxiliary pendulum bearing sleeve (2) and the other free end is connected with an iron hook (14) of a steel rope (13) at the output end of an electric block (6); a main pendulum hinge (5) is fixed on the rotating shaft (3), one end of a main pendulum (8) is fixed on the main pendulum hinge (5) and the other end of the main pendulum (8) is connected with a pendulum bob (16); the main pendulum is provided with a main and auxiliary pendulum connecting device which comprises a proximity switch for detecting whether the auxiliary pendulum is close to the main pendulum and a main and auxiliary pendulum lock; and the side crash device also comprises a PLC control system and a human-machine interface. During experiment, the auxiliary pendulum is close to the main pendulum and the main pendulum is lifted to the position of an original angle; and the main pendulum is freely and downward swung. The device has the characteristics of accurately adjusting the speed and preventing secondary crash.
Description
Technical field [0001] The invention relates to a speed-adjustable automobile side collision device and an experimental method, belonging to the technical field of automobile safety performance testing. Background technique [0002] The side impact test bench is a low-cost, high-repeatability test device used to study the protection of car door structure, door interior and side airbags for occupants in the car. [0003] The international research on the test method of side impact trolley began in the mid-1990s. Mainly represented by Seattle Safety Company of the United States, IST Company of the United Kingdom, DSD Company of Austria and Mitsubishi Company of Japan. These types of side-impact trolley test devices are mainly used to simulate the movement of a certain point on the inner panel of the car door, and have high cost requirements. It mainly uses the cylinder as the driving device, and the focus of the research is to analyze the speed characteristics of the inner p...
