Impulse testing system

Abstract

The invention discloses an impulse testing system, which comprises a pressure sensor and / or a displacement sensor, a data acquisition device and an impulse testing device, wherein the data acquisition device is used for receiving pressure information, generating first timed triggering information when the pressure sensor senses the pressure information, generating second timed triggering information when the pressure sensor stops sensing the pressure information, and / or receiving position information, generating third timed triggering information when the displacement sensor senses the position information and generating fourth timed triggering information when the displacement sensor stops sensing the position information; the impulse testing device comprises a timing unit and a processing unit, wherein the timing unit is used for obtaining timing information and the processing unit is used for calculating an impulse value according to the timing information and the pressure information or the position information. The impulse testing system provided by the invention has the advantages the automatic processing can be realized to obtain the impulse, the automatic degree is high, the manual calculation at a later stage is not required, the result is directly obtained, the interference of human factors is avoided and the accuracy of the testing result is guaranteed.

Description

technical field [0001] The invention relates to an impulse testing technology, in particular to an impulse testing system. Background technique [0002] Impulse is one of the parameters to measure the mechanical effect of impact load on shell structures such as containers. The current impulse test method has the impact pendulum method. It converts the received impulse into gravitational potential energy, and the swing range can intuitively describe the magnitude of the impulse to be measured. Its volume is large, and its design, processing and data processing are complicated. In addition, it is difficult to accurately determine the center of mass of the pendulum, which has a great influence on the accuracy of the impulse measurement. [0003] Therefore, the accuracy of the impulse test system is a technical problem to be solved urgently. Contents of the invention [0004] In view of this, the present invention proposes an impulse test system to ensure measurement accur...
