Abstract

The invention discloses a method for testing a motor experience distortion index. The method for testing the motor experience distortion index comprises the following steps: acquiring a motor parameter, wherein the motor parameter is a linear parameter or a nonlinear parameter; selecting a specified frequency of the distortion test and generating a single-frequency voltage signal with the specified frequency; predicting the predicted displacement of the motor vibrator under the excitation of the single-frequency voltage signal according to the linear parameter or the nonlinear parameter of themotor; adjusting the amplitude of the single-frequency voltage signal according to the target displacement value of the motor oscillator and the maximum value of the predicted displacement so as to enable the maximum value of the predicted displacement to approach the target displacement value; acquiring vibration data of the motor vibrator under the excitation of the single-frequency voltage signal after amplitude adjustment; and calculating the motor distortion from the vibration data. Compared with the prior art, the method for testing the experience distortion index of the motor can reflect the distortion condition of the motor in practical application.

Description

【Technical field】 [0001] The invention relates to the technical field of motor distortion testing, in particular to a testing method for motor experience distortion indicators, electronic equipment and a storage medium. 【Background technique】 [0002] In recent years, people have paid more and more attention to haptic feedback. The motor is one of the core devices providing tactile feedback. In order to achieve a specific vibration effect, haptic feedback designers often need to know the distortion of the target motor at each frequency in advance, so as to better combine with the signal design work. [0003] In the related art, single-frequency signals of different frequencies with a constant voltage (such as the rated voltage of a motor) are usually used for distortion testing. For frequency points far away from the motor resonance frequency, the displacement and vibration of the vibrator excited by this distortion test method are very small. In order to ensure the tactil...
