Abstract

A steel frame was one of the key components of the drop tower. With the steel frame’s guide, the sample could be dropped from a given height with a position considered, and the steel frame was decelerated with its kinetic energy absorbed with the flow of water in the buffer. The drop tower demanded that the steel frame must be 5.0 meters long, which would reduce its stiffness and the impact load would change with the variety of the steel frame structure. In order to take the change of impact load into consideration, the water flow was taken into the analysis model by the arbitrary Lagrange-Euler method. The design principle was built by the dynamical analysis of steel impact on the buffer. With the numbers of numerical analysis of the designed structure, the final steel frame with high impact load resistance was gained. Keywords: gliding steel frame, impact, design.
