Last longer is wanted, not only influences the time cycle in experiment, but also easy to produce security risk, is also easy to generate to experiment
The multiple impacts of object ' bumper ', it is therefore, extremely important to the control of remaining pendulum.
Remaining pendulum control aspect, existing test device mainly control the pivot angle of oscillating weight axle, directly frequently with control methods are seized
Stop to pivot angle to zero, control is that pendulum of stopping is completed in rubbing action, but it is controlled by the friction plate (or friction band) coaxial with balance staff
Effect processed needs several pendulums to complete back, and there is also the risks that balance staff twists off；In order to preferably control remaining pendulum, avoid above-mentioned
Risk and unfavorable factor, the method that test device must take brake pendulum safer and more effective, the present invention design be exactly to solve
This problem.
Invention content
The purpose of the present invention is to provide a kind of Ce Sha mechanisms of bumper simulating impact test device, specifically exist
Aerodynamic side brake mechanism is installed in main body rack both sides, and the position of pendulum is detected using bob position sensor, when detecting that pendulum is complete
After the shock with bumper, starting both sides side brake cylinder, push side brake piece forms extrusion friction with side brake plate simultaneously, leads to
It crosses frictional resistance and directly consumes kinetic energy, and pendulum case is made to stop in 1-2 remaining pendulum cycles, to reach safety, quickly stop
On the one hand purpose can slow down impact of the pendulum to main body rack, on the other hand, reduce pendulum number of oscillations and amplitude, prevent from putting
Hammer forms secondary impact to bumper, in addition, also improving the safety of integral device, improves the work effect of test
