Rotary hammer type impact test device

Abstract

The invention provides a rotary hammer type impact test device, and belongs to the field of impact tests. The rotary hammer type impact test device comprises guide rails, a hammer which is arranged on the guide rails and is capable of sliding on the guide rails, and a hammer acceleration device. The guide rails comprise a linear guide rail and a round guide rail and are arranged horizontally, wherein the round guide rail comprises two parts, namely a circular-arc guide rail and a hammer release guide rail, the linear guide rail is tangent to the round guide rail at a connection point, and the hammer release guide rail is movably connected with the round guide rail in the position of the connection point. The hammer acceleration device comprises a driving rod, wherein one end of the driving rod is fixed in the center of the round guide rail in a rotary mode, the other end of the driving rod is connected with a hammer in a releasable mode, and the hammer acceleration device further comprises a power mechanism used for driving the driving rod to rotate. The impact test machine not only better improves the impact energy, but also saves the space, lowers costs, better reduces the influence on surrounding buildings and instrument equipment from impact force.

Description

technical field [0001] The invention relates to an impact test device, in particular to an impact test device that accelerates a hammerhead through rotation. Background technique [0002] The experimental study of structural crashworthiness is an important part of impact dynamics, and different impact loading methods can be used in the impact test according to the range of impact velocity. For high-speed and ultra-high-speed impact loading experiments, experimental methods such as Hopkinson compression rods or gas cannons can be used to achieve. For a large number of impact problems in engineering, it usually belongs to the low-speed impact process. Experiments simulating such problems often use the drop-weight impact loading test device, which is a simple, reliable and repeatable loading device. [0003] The drop hammer testing machine is composed of a drop hammer, a support, a bracket, an automatic hook device, a protective net, and a hoist. on file. Sometimes in order ...
