summary:

The test system is used to test the motion noise (abnormal sound) of various motors and their transmission modules. Refer to the standard GB / t10069.1-2006 to collect motion noise and vibration spectrum by using acoustic microphone or vibration acceleration acquisition circuit. Set control standards according to the characteristic differences between OK and ng signals to automatically distinguish the quality of products and avoid subjective differences caused by human listening.

Technical features:

one Acoustic sound insulation environment: ≤ 40dba @ 85dba

two Provide control of motor speed, angle, direction and on load torque

three Provide the sound loudness evaluation index of motor running noise, and output the motor noise value

four Provide programmable analysis filter - analyze the noise components and characteristics of each frequency band

five Identify the continuous or discontinuous noise generated by motor operation process: friction, tooth collision, looseness, etc

six Detect the motor operation process: vibration frequency, vibration GRMS, sound power CF FFT RTA TDM analysis spectrum

seven Realize automatic test (UPH: 200pcs), automatic output of OK / ng results, and human ear monitoring function

eight The software system is independently developed by our company to meet the functional requirements of differentiated customers
