Abstract

The invention discloses a knocking head for knocking test and a knocking test device. The knocking head for knocking test comprises a knocking weight and a driving assembly which are movably or flexibly connected without mutual energy transmission. When the driving assembly does not move, the knocking weight is stationary. When the driving assembly is started, the knocking weight is released, falls freely under the effect of weight of the knocking weight and knocks a tested product. In the process, there is no energy transmission between the driving assembly and the knocking weight. The kinetic energy of the driving assembly is not transmitted to the knocking weight, and the kinetic energy borne by the tested object is determined by the mass of the knocking weight and the distance between the surface of the tested object and the lower end of the knocking weight. The two parameters are very easy to control and adjust, so that acquisition of constant knocking force is easy and reliable. After the completion of knocking, the driving assembly drives the knocking weight to return to the initial position for next knocking, and all test work is thus completed.
