Embodiment 1

[0040] refer to Figure 1 to Figure 11 As shown, a heavy-duty vehicle fuel tank oil sloshing characteristic test device includes a bench test platform, and the bench test platform includes a test piece connection unit and a power unit, and the power unit includes a chassis 1 and a driver 2. The chassis 1 is fixed on the ground, and the driver 2 is installed on the chassis 1. The driver 2 includes a worm gear reducer and a bearing seat for installing the main shaft. The output end of the driver 2 is provided with a reciprocating transmission mechanism. The test piece connection unit includes a sliding bracket 3, a fixed bracket 4 and a fuel tank connector. The sliding bracket 3 is slidably arranged on the bottom frame 1. The sliding bracket 3 is movably connected with the reciprocating transmission mechanism. The sliding bracket 3 drives the reciprocating Realize left and right reciprocating movement under the effect of transmission mechanism, the middle position of the front a...

Embodiment 2

[0057] A test method for a test device for the sloshing characteristics of a fuel tank of a heavy truck vehicle, comprising the following steps:

[0058] A. First arrange the vibration sensor on the fuel tank bracket 17 and the strap 18, arrange the resistive strain gauge on the anti-wave plate 19 and the fuel tank end cap 22, arrange the oil pressure sensor on the fuel tank end cap, and arrange the fuel tank end cap 22 and the 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 pin 20 and the lower pin 21, the strap 18 is hooped on the fuel tank outside the wave plate 19 and It coincides with the position of the anti-wave plate 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 realize t...

Abstract

The invention discloses a heavy truck fuel tank oil shaking characteristic testing device and method, and belongs to the technical field of oil tank testing. The device comprises a power unit and a test piece connecting unit, the power unit comprises a bottom frame and a driver, the bottom frame is fixedly arranged on the ground, the driver is installed on the bottom frame, and a reciprocating transmission mechanism is arranged at the output end of the driver; the test piece connecting unit comprises a sliding bracket, a fixed bracket and an oil tank connecting piece; the sliding support is slidably arranged on the bottom frame, the sliding bracket is movably connected with the reciprocating transmission mechanism; first hinge supports are fixedly connected to the middle positions of the front side and the rear side of the sliding bracket, second hinge supports are fixedly connected to the middle positions of the front side and the rear side of the fixed bracket, the two second hinge supports and the corresponding first hinge supports are jointly connected with connecting pins, an elastic buffer structure is connected between the fixed bracket and the sliding bracket, and the oil tank connecting piece is fixedly installed on the fixed bracket. The motion condition of the fuel tank of the heavy truck is truly simulated, and a positive effect is achieved for the structural improvement or research and development of the fuel tank.

Description

technical field [0001] The invention relates to the technical field of fuel tank testing, in particular to a test device and a test method for the oil sloshing characteristics of a fuel tank of a heavy truck vehicle. Background technique [0002] Automobile transportation occupies an important position in my country's national economy and social production. In railway, highway, waterway, air and pipeline transportation, road freight volume accounts for about 70% of the total. With the advantages of point-to-point, convenience, and relatively low freight rates, heavy trucks play an important role as the main means of transportation for road freight. Similarly, due to the large cargo capacity of heavy-duty trucks and the relatively harsh working conditions, the performance requirements for heavy-duty trucks are further improved, not only including power, oil, etc., but more importantly, safety. [0003] During the driving process of heavy-duty trucks, it is inevitable that th...
