Abstract

The invention discloses a three-dimensional adjustable dropping hammer experiment workbench system which achieves impact experiment to any points on a test piece in a three-dimensional space coordinate. The system includes an experiment fixture and a test piece, a transversal workbench, a slide saddle, a longitudinal workbench, a vertical lifting column, a dropping hammer punch head, an anvil and a feed scale ring. All of the parts are assembled through dovetail grooves and are connected to each other through bolts, so that the system is easy to assembly and operate and is detachable and portable. In the system, the workbench transversally and longitudinally moves through a screw rod and the vertical lifting column moves vertically through a vertical lifting hand wheel. The movement distance can be accurately regulated through the feed scale ring. By measuring corresponding parameters and substituting the parameters into a calculation formula, accurate expressions of different dip angles can be obtained. The system can achieve impact on the test piece at any positions and any angles, is multi-functional, and effectively solves a problem of necessity of designing different workbenches for different types of test pieces during a dropping hammer experiment.

Description

technical field [0001] The invention relates to the technical field of experimental workbench systems, in particular to a three-dimensional adjustable drop hammer experiment workbench system. Background technique [0002] The response of a structure subjected to impact loading has many different laws than that of a static load case. During the impact of rods, plates, rings, shells and other structures at medium and low speeds, the huge kinetic energy of the impacting objects will cause large deformation, buckling, fracture, and even collapse of such flexible structures, resulting in structural failure and catastrophic accidents. A large number of low-speed impact problems in engineering are realized by using the drop weight impact test system. The large drop hammer impact test system is a simple, reliable and repeatable loading device that is completely fixed to the ground. During the experiment, the loading of test pieces of different sizes is realized by adjusting the dro...
