The invention discloses a dynamic response evaluating device for a strain type pressure testing system, wherein the device belongs to the field of evaluation testing. The dynamic response evaluating device comprises a base, a pressure sensor, a connecting block, an elastic device, a guide rail, fixed magnets, a speed measuring magnet, an electromagnetic induction box, a driving mechanism, a slideblock, an ejection spring and a top seat. The lower end of the elastic device is connected with the sensing end of the pressure sensor through the connecting block. One end of the guide rail penetrates through the center of the elastic device and is fixedly connected with the connecting block. Two fixed magnets are symmetrically fixed to the front side and the back side of the upper end of the elastic device. The speed measuring magnet is fixed to the right side of the upper end of the elastic device. The slide block is fixed to the electromagnetic induction box. The slide block and the electromagnetic induction box sleeve the guide rail. The outer wall of the slide block is provided with teeth. The driving mechanism is coupled with the teeth. One end of the ejection spring abuts against the slide block, and the other end is fixedly connected with the top seat. The top seat is fixed to the other end of the guide rail. The evaluating device has high transplantability and is suitable forevaluating and verifying different pressure experiment acquisition systems.
Description
technical field [0001] The invention relates to a dynamic response evaluation device of a strain type pressure test system, which is used as a standard known signal generation source to test the dynamic response of the experimental system, the accuracy of signal collection, etc., and belongs to the technical field of test and test. Background technique [0002] With the continuous development of science and technology, the fields that need dynamic testing and signal acquisition are increasing. In the test process, it is often necessary to determine the signal as an input to test and evaluate the dynamic response characteristics and accuracy of the test system. The signal generator, also known as the signal source, is generated by the core part of the instrument, and then through signal conditioning such as amplification and attenuation, and finally outputs the signal to the outside of the instrument. Signal generators are widely used in circuit experiments and equipment tes...
