Novel simulated leg-type impactor

The utility model relates to an impact test device used for an automobile bumper, in particular a novel simulated leg-type impactor. The novel simulated leg-type impactor includes a cylinder-shaped simulated leg; an acceleration sensor mounting seat is fixed on the outer wall of the cylinder-shaped simulated leg; an acceleration sensor is fixed in the acceleration sensor mounting seat; when a test is performed, the acceleration sensor is emitted through an emitter, so that a position at the back surface of the cylinder-shaped simulated leg, where the acceleration sensor is mounted, is made to impact an automobile bumper test piece; and the acceleration of the whole simulated leg-type impactor is obtained through an externally-arranged velocity measuring instrument. With the novel simulated leg-type impactor of the utility model adopted, accuracy of impact directions can be ensured, an emission mechanism and an guide mechanism will not be damaged, and accurate test data can be effectively obtained.
