Problems solved by technology
Whether it can be effectively tripped and the swing control of the hoisting rope after tripping will affect the uniformity and certainty of the starting point of the impact test, as well as the potential safety hazards caused by the irregular swing of the hoisting rope.
Pneumatic tripping schemes are mostly used in the industry and the free swing of the hoisting rope after tripping is not controlled, which will lead to unstable starting position of the pendulum box, continuous collision between the pendulum and the bumper, and non-directionality of the swing, etc. The problem of unreliable and hurtful data measurement

The invention discloses a pendulum locking and tripping device for simulated collision of an automobile bumper. The device comprises a steel rope take-up and pay-off mechanism, a steel rope for pulling up a pendulum, a tripping assembly and a pendulum limiting assembly, wherein the steel rope is also used for hanging the tripping assembly, and the pendulum limiting assembly is used to limit the maximal pull-up height and the minimal pull-up height of the pendulum. The device is characterized in that the steel rope take-up and pay-off mechanism is arranged in a back upper position of the pendulum, rotates to take up the steel rope and releases and pulls up the steel rope, the tail end of the pulled-up steel rope is connected with the tripping assembly, the tripping assembly is arranged behind the pendulum and provided with a swing limiting steel rope, and the top end of the swing limiting steel rope is connected to the pendulum limiting assembly.
Description
technical field [0001] The invention relates to the technical field of pendulum separation during a collision, and more specifically, to a locking and releasing device for a pendulum in a simulated collision of an automobile bumper. Background technique [0002] During the test on the automobile bumper pendulum impact test platform, the pendulum is pulled up at a certain angle by the hoist placed at a high position and then released to complete the free impact test. Whether it can be effectively tripped and the swing control of the hoisting rope after tripping will affect the uniformity and certainty of the starting point of the impact test, as well as the potential safety hazards caused by the irregular swing of the hoisting rope. Pneumatic tripping schemes are mostly used in the industry and the free swing of the hoisting rope after tripping is not controlled, which will lead to unstable starting position of the pendulum box, continuous collision between the pendulum and t...
