[0056] Example 2:
[0057] A testing method of a device for testing the sloshing characteristics of fuel tank oil in a heavy truck vehicle includes the following steps:
[0058] A. First, arrange vibration sensors on the fuel tank bracket 17 and strap 18, arrange resistance strain gauges on the wave plate 19 and the fuel tank end cover 22, arrange the oil pressure sensor on the fuel tank end cover, and place the oil A float level gauge is arranged on the wall of the fuel tank between the corrugated plates 19;
[0059] B. Fix the fuel tank on the support plate 16 of the fixed bracket 9 through the fuel tank bracket 17, the strap 18, the upper piercing pin 20 and the lower piercing pin 21, and the strap 18 is hooped on the fuel tank located outside the wave plate 19 and Coincide with the position of the wave breaker 19;
[0060] C. Then start the driver 2, drive the connecting rod 11 to move back and forth through the crank 10, and at the same time drive the sliding bracket 3 to realiz...
