Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0046] like figure 2As shown, 1 is the base of the test bench, 2 is the guide rail, 3 is the ball screw, 4 is the nut, 5 is the support bearing, 6 is the coupling, 7 is the microphone array, 8 is the data collector, 9 is the computer, 10 is a grating ruler, and 11 is a servo motor. The ball screw pair is installed on the comprehensive performance test bench, and M microphones form a uniform linear array, which is placed on one side of the test bench, parallel to the lead screw. The height of the microphone array is consistent with the nut, or slightly higher than the nut. The microphone array picks up the sound signal, and the grating ruler collects the position information of the nut, the sound-producing part of the ball screw pair. The main sources of interference at the noise measurement site are the noise of the servo motor and the noise of th...
