Pressure rod strain type impact force value measurement device and system

Abstract

The invention provides a pressure rod strain type impact force value measurement device and system. The device comprises a base, a measurement part arranged above the base, and a fixing part arranged on the base for fixing a transmission rod. The measurement part includes a bearing member, the transmission rod, a pressure rod and a pressure rod support. The bearing member bears the impact force. The transmission rod is used for transmit the impact force. The pressure rod generates a corresponding strain according to the impact force value and outputs a corresponding strain electrical signal. The strain electrical signal output by the device is subjected to signal amplification, signal collection, analog-to-digital conversion and analysis by a host computer, and then the size of the measured impact force value can be known. The device and the system are reasonable in structure and can quickly measure the impact force value reliably.

Description

technical field [0001] The patent of the present invention relates to the field of impact force value measurement, in particular to a pressure rod strain type impact force value measurement device and system. Background technique [0002] With the continuous development of mechanical industry technology and electronic technology, the application of various sensors has become more and more popular. Various tests in the field of mechanical engineering use a lot of strain sensors. For the test of impact force, the impact operation is very destructive. It is difficult for the measuring sensors in the prior art to directly withstand the impact force and detect the impact force. Most of the measuring sensors can only carry out static test, but cannot realize impact force measurement. At present, most of the equipment and devices used to measure the impact force value have the problems of complex structure, inconvenient use, difficult control, and inaccurate measurement results, r...
