High-iron glass: four secrets you do not know

Secret one: why do not look out the window does not stare the scene is not deformed?

Glass refractive index of the same train damping performance is good

High-iron car front window glass is a hyperboloid structure, the glass itself has a lot of layers, between layers and layers to maintain a high degree of consistency, this will not affect the optical effect of glass to see things not deformed. High-caliber side window glass visual effect is excellent, improve the glass in the thickness, flatness on the error, and do the glass material composition of the full homogenization, to ensure that the same refractive index, see the scene will not be deformed, and no glass Visual effects, looks comfortable, not dazzling.

The ordinary glass due to the existence of a certain optical distortion, through the glass to see the scene will produce deformation, at the same time, for high-speed movement of the scene will produce the speed of superposition, resulting in dazzling, bring a sense of dizzy. High-speed EMU train shock absorption performance is good, irregular bumps reduced, the scene shaking smaller, running very smooth, quiet, to the passengers with a slow feeling, the passengers sit there will not have a sense of dizzy.

Secret II: high-speed rail operation in the process of encounter small stones will be broken it?

The window can not be urged to withstand the speed of 355 km of aluminum bomb impact!

The current high-speed rail train running speed of 380 km / h, high speed also means that high-risk, high-speed train will be around the air compression, air resistance greatly improved, which makes the train in the process of moving through a road Brick wall, the resistance can be imagined. Therefore, in order to ensure the safety of the train, the most vulnerable windshield in the train must be hard to remind.

High - iron glass impact test

The above video is the impact test of high-iron glass, 1kg heavy aluminum bombs at a speed of 355 km per hour to the high-speed rail train on the glass, although the floor is broken glass, the window was aluminum bombs hit a pit, but the glass And was not penetrated and off the box, the window and no glass slag splash, hand hit the impact area is still very strong.

High-speed rail special attention to high-speed impact of glass material performance, which is the glass processing enterprises in the production of a threshold. Take the CRH380A EMU as an example, which requires the front windshield to withstand 1kg of aluminum bombs at a speed of 540km / h and can not be penetrated. Side window glass requires good visual performance, safety performance, energy saving performance and environmental performance.
