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.”
Those who did not understand, those who could not speak, those who could not write, and those who could not paint, eliminated themselves.
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.
Flange bolt pre-tightening force is the pre-tightening force in the direction of the axis of the bolt generated between the bolt and the connected part under the tightening torque during the bolt tightening process.
Bearing heat treatment is directly related to the subsequent processing quality, which ultimately affects the performance and life of the parts.
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.
In the forging production, according to the law of constant volume, it is possible to carry out technological calculations such as the size of the forging, the size of the process parts and the size of the mold.
China is in an important position in the international manufacturing industry, manufacturing technology is facing upgrade, and economic development is facing transformation. The increase in labor costs has made robot technology an important development opportunity in China, but the demand for robots in turn has put forward higher requirements for computer-related scientific research.
At present, the issue of “de-globalization”, which is hotly debated by Chinese public opinion, is largely related to the issue of “decoupling” or “de-sinicization” of the West and China. Many people expressed concern about “de-globalization”, in fact they are worried about the negative impact of “de-sinicization” on China’s own interests, and such concerns are not unreasonable.
Mechanical seals have become one of the most common forms of sealing in motorized equipment in oil refining and chemical installations. Moreover, with the continuous improvement of their design and manufacturing level and the continuous development of new materials, their application scope will be further expanded.
Automation involves many disciplines, whether it is mechanical or electrical, automation involves motors, mechanisms, analog electrical, digital, single-chip, programming, algorithms, control theory, finite element analysis, etc., from traditional industrial control to PLC, from ordinary servo The application to CNC machine tools, from robots to artificial intelligence, from embedded operating systems to dedicated systems, involves too many fields, and in this large field, no matter what direction we develop in, it is not a deviation. This is the advantage of automation. So, as long as you want to work hard, you can become a bull in any direction!
Industrial software refers to software used in the industrial field, including systems, applications, middleware, embedded, etc. Generally speaking, industrial software is divided into programming languages, system software, application software, and middleware in between. The system software provides the most basic functions for computer use, but it is not aimed at a specific application field. The application software is just the opposite. Different application software provides different functions according to the users and the fields they serve.
How to determine your understanding of manufacturing? The easiest way is to grab a drawing of something you design yourself. Can you tell whether it has been fully manufactured? Casting, forging, turning, pliers, milling, planing, grinding, just like this, certainly not.
Traditionally, noise control engineers often used test methods to identify noise problems and repeated test methods to solve the problems. However, now many industries such as automobiles, aerospace, heavy equipment, industrial equipment, air conditioning, heating, home appliances, etc., are more focused on introducing simulation models for simulation at the early design stage. Therefore, design evaluation …
