Abstract

The invention discloses a method for detecting the wind tunnel test parameters of wiper products. Aiming at the special test requirements of the wind tunnel test, the circuit loop design is added on the basis of the existing detection, and the detection data of different loops are collected by PLC programming, and through the conversion The device restores the real-time pulses of different parameters into data and presents them on the display screen, and draws a curve while recording the real-time data. The curve records all the data from the beginning to the end of the test and displays the relationship between the parameters on the same screen for testing. Results evaluation and problem analysis. The invention can detect the real-time data and changing curves of various parameters of the motor under the conditions of different wind speeds, different water spray volumes, different speeds and different working hours, and save the test data; at the same time, it can be applied to general test items , because the general test items do not have as many performance parameters as the wind tunnel test requires, when using the present invention, only some of the functions may be required to meet the requirements.

Description

technical field

[0001] The invention belongs to the technical field of automobile wiper products, and in particular relates to a method for detecting wind tunnel test parameters of wiper products. Background technique

[0002] During the test process of the motor, especially the wiper motor, its performance parameters will change due to different working conditions. For example, the working condition of the wiper product changes in real time during the wind tunnel test, so the parameter detection method is more complicated. When the wind tunnel test of wiper products is carried out, the current, voltage, temperature and speed of the motor are important indicators to measure the performance of the motor. When the wind speed changes from 160km / h to 250km / h, the test includes motor performance, mechanism performance and blade performance. The whole test process takes several hours to complete. During the test, the parameters of the wiper motor vary according to the load. Chang...
