Car Rain Protection Airproof Performace Test Method Based on Ultrasonic

Based on ultrasonic principle, the car rain protection airproof performance test method was proposed after the main problems of the current artificial rain test were put forward. In the new method, the detection and evaluation was separated which means that the real-time detection, in the use of ultrasonic, could be achieved as the car enter the venue and according to the on-site analysis of the collected data, by the master computer, the evaluation could be given. The test results show that the new test method would save time and simplify the test procedure and so on.
