Introduction of the aluminum wave plate of the tank truck crack

When filling the liquid gas medium in the tank truck, it is necessary to leave a corresponding gas phase space in the tank truck. Different media have different filling coefficients. Due to the existence of gas phase space in the tanker, when the tanker is running, the liquid in the tanker will continuously impact the tanker, affecting the safe operation of the tanker. Setting the wave-proof plate can slow down the instantaneous impact force on the tank body when the liquid fluctuates, and improve the driving stability and safety of the tanker.

Why did the aluminum wave plate of the tank truck crack?

1. The strength and stiffness of the openings of the aluminum wave shield are insufficient, and the fatigue life of the aluminum wave shield is not considered. During the transportation of the tank, due to the complex road conditions, frequent starting and braking are required, especially emergency braking. The joint is often affected by the instantaneous huge alternating impact load, and the long-term air flow will lead to the fatigue damage of the wave board.
2. Influence of defects in processing, manufacturing and installation of aluminum wave board. In order to facilitate the installation of corrugated board, the factory opened long round bolt holes in the corrugated board, which weakened the strength and rigidity of the bolt opening of the anti-wave board. Due to the insufficient strength of the aluminum wave shield, the wave shield moves left and right under the impact of alternating loads, increasing the wear at the opening, making the long hole longer, weakening the strength and stiffness of the opening, and easily damaged.

The solution to the cracking of the aluminum wave plate of the tank truck

1. Increase the thickness of the aluminum corrugated plate: the thickness of the aluminum corrugated plate of the tank car is 2mm. Due to the weakening of the strength and stiffness at the opening, the fatigue life is fully considered, and the thickness of the corrugated plate is increased. ability to reduce cracking.
2. Change the structural form of the aluminum corrugated board: due to the poor stiffness of the aluminum alloy, in order to increase its stiffness, a corrugation is punched out on the anti-wave board. Then use two corrugated boards with a width of 100mm, and connect the upper, middle and lower wave boards with bolts in the middle (length direction) of the anti-wave board to form a whole and enhance its ability to resist the impact of liquid. 
3. Change the manufacturing and installation process of the wave-proof board: For the convenience of installation, the factory processes one end of the bolt hole of the wave-proof board into an oblong bolt hole. When the wave-proof board is subjected to a longitudinal impact force, the corrugated plate can move there, so the stress concentration is caused here. In order to eliminate or reduce the stress concentration at this place, it is recommended that the factory process this place into a circular hole. Due to the deviation of the tank body and the angle steel support plate during the manufacturing and installation process, the installation connection hole at one end of the anti-wave plate should be drilled and installed on site to prevent the installation hole from being too large and causing stress concentration.
