Description

Technical Field

[0002] In modern industry and scientific research, the performance evaluation of materials is of vital importance. With the continuous development of materials science, the demand for accurate determination of the impact resistance of materials is increasing. The traditional building material performance testing method requires manually controlling the falling hammer to impact the object to be tested by free fall, or manually swinging the hammer to impact the object to be tested. The height of the hammer, the force of swinging the hammer, and the position of the impact on the object to be tested are not fixed.

[0003] In the prior art, the impact resistance test method for building materials can convert the impact force of the falling hammer on the inspected object by lifting the falling hammer to a certain height and changing the weight of the falling hammer. When performing impact testing on building materials, the height of the falling hammer is difficult to control accurately, the falling hammer may tilt when falling, and the position of the building materials cannot be fixed, which will affect the impact resistance test of the building materials. In addition, the building materials may be broken into pieces and splashed out due to the strong impact force of the falling hammer, causing varying degrees of damage to people or objects at the testing site.
