What is the material of aluminum alloy?

Today, people are increasingly demanding low-carbon environmental protection, aluminum alloy has become a substitute for many metals, its low density, high strength, easy processing and other advantages, more and more applications in automobiles, high-speed rail, aviation, ships The wider it is, the aluminum alloy will definitely make a greater contribution to human development.

666! The principle of simplicity and the magic number 6

Unless we consciously change our thinking and behavior, how to simplify complex things will be an eternal challenge. As Steve Jobs said: “Simple may be harder than complex: you have to work hard to make your thinking clear and keep it simple. But in the end it is still worth it, because once you do this, you can create miracles.”

Why the bolts “If it doesn’t loose, it will break as soon as it looses.”

When the bolt is broken, the easiest conclusion that people can draw is that the strength is not enough, so most of them adopt the method of increasing the strength level of the bolt diameter. This method can increase the pre-tightening force of the bolts, and the frictional force has also been increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, its investment is too large, and the benefits are too small.

Motor selection parameters, principles and methods

When the motor is running under load, the total internal loss is converted into heat energy to increase the temperature of the motor. The poor heat resistance in the motor is the insulating material. If the load of the motor is too large and the loss is too large to make the temperature exceed the allowable limit of the insulating material, the life of the insulating material will be shortened sharply.
