Abstract

The invention discloses mechanical shock test equipment, comprising a base, guide posts, a driving device, an impact hammer, a cushion plate, a cross beam, an acceleration sensor, a data acquisition card and a computer, wherein the impact hammer sleeves the guide posts and is hung on the cross beam, the cushion plate is arranged on the upper surface of the base and positioned below the impact hammer, a sample is placed on the cushion plate, the driving device can drive the impact hammer to ascend and descend on the guide posts, the impact hammer comprises a main body structure and a hammerhead which is connected under the main body structure in a detachable manner, the acceleration sensor is arranged in a groove of the lower surface of the hammerhead, the lower surface of the hammerhead is further provided with a cover plate used for covering the acceleration sensor, the data acquisition card acquires acquisition electrical signals detected by the acquisition sensor and transmits acquired data to the computer, and a software platform is used for displaying the acquired data. The multifunctional mechanical shock test equipment disclosed by the invention can accurately obtain short pressure in the test process and increase test accuracy.

Description

technical field [0001] The invention relates to the technical field of mechanical shock, in particular to a multifunctional mechanical shock test equipment capable of accurately obtaining shock pressure during a test and improving test accuracy. Background technique [0002] The purpose of the mechanical shock test is to determine whether the various properties fail when the product is subjected to a series of shocks at normal and extreme temperatures. [0003] The technical indicators of the impact test include: peak acceleration, pulse duration, velocity variation (half sine wave, rear peak sawtooth wave, trapezoidal wave) and waveform selection. There is no special requirement for the number of impacts, and each surface is impacted 3 times, a total of 18 times. [0004] Many products will be impacted during use, loading and unloading, and transportation. The magnitude of the shocks varies widely and is of a complex nature. Therefore, impact and crash reliability tests ...
