material in conduction 9.2 Test the product according to the relevant provisions of "General Test Objects" in Section 4. 9.3 Test this product using instruments such as wheel gauge, vehicle penetration measuring instrument, stopwatch, ruler, cup marker, etc. 9.4 Test method 9.4.1 Determine the radius of the four wheels respectively. Non-loaded and special driving conditions. The wheels begin to comply with the current imprint: the car is running at a relatively fast speed, on the bridge. When the center of the road is open, the input and output are concave, the length is greater than the vehicle load, the wheel speed is too long, and the total length of the moving wheel is calculated according to the speed center. The rolling radius of the moving wheel is obtained by formula (10): S
In the system: r
The total circumference of the moving wheel + n
The total circumference of the three wheels Degree,
Wu test results according to Chong A table A14 written in English.
