Abstract

The invention provides a rapid mode testing device for a vibration isolation system and a testing method of the rapid mode testing device. The testing device comprises a tension meter, a displacement measurer and a computer. A tension handle is arranged on the tension meter. The tension meter provides constraints and excitatory input for mode testing. The displacement measurer is composed of a base, an adjusting rod, a scale, an indication rod, a ball and a laser displacement sensor. The displacement measurer has the function of measuring displacement in two testing states, namely, the vertical direction and the horizontal direction. A first arc groove is formed in the scale so that the ball can be conveniently assembled. A second arc groove is formed in the indication rod. The laser displacement sensor conducts real-time displacement measurement on the movement of the indication rod in the testing process. The computer contains a data acquisition card for testing data of the tension meter and the displacement measurer. By means of the rapid mode testing device and the testing method, the mode frequency in the main rigidity direction is conveniently and rapidly tested while the effectiveness and accuracy of mode testing are ensured.

Description

technical field [0001] The invention relates to a test device and a test method thereof, in particular to a modal quick test device of a vibration isolation system and a test method thereof.
