Abstract

A mechanical structure crashworthiness simulation experiment platform disclosed by the present invention comprises a table-board, a table body, synchronous drive systems, a waveform generation device and shock isolation devices. A punch is arranged on the table-board, the waveform generation device is arranged between the table-board and a pedestal and is located in the center of the table-board, the synchronous drive systems are arranged at the two sides of the table-board respectively and are connected together via a main shaft, and the plurality of shock isolation devices are distributed between an upper bottom plate and a lower bottom plate evenly. The mechanical structure crashworthiness simulation experiment platform of the present invention adopts the dual-upright column table-board, is large in size and can carry out the whole machine test. The waveform generation device of the present invention does not need to replace an elastic cushion, but just needs to adjust the clamping area of a sleeve to the elastic cushion, and the adjustment process is simple and rapid. The shock isolation devices are arranged between the table body and the ground, thereby not needing the special-purpose foundation, and saving the cost. Meanwhile, the collision waveform is optimized, the generation of the high-frequency harmonic is reduced, and the natural frequency of a collision table is less than 1 HZ.

Description

technical field [0001] The invention belongs to the technical field of a mechanical environment simulation experiment platform, and in particular relates to a mechanical structure collision performance simulation experiment platform.
