Hello, everybody. Try to imagine this situation, what if I bring a well-made robot here? What if this robot can dance, sing and even cook a delicious meal for you? Would every one of you show greatest interest in this fantastic big toy? … Yes, I believe you do. All of you like high-tech machines. Most of you ask your parents to buy you a laptop after college entrance exam, some of you may possess an iphone and use it to blog and surf the Internet frequently during your break between classes. To boys, model plane is also a common dream when you are little. But with which on earth could engineers make so many magnificent machines and even let them move?
Today, I will tell you how they make it, with showing you the three main factors for engineers to design a product. Our emphasis will be laid on mechanical structure, electric and simulation in the following.
First of all, let’s talk about mechanical structure. Structure is to machine, as the body to a human being. As the first but foremost step of manufacturing, designing suitable structure helps to support the weight of a machine, strengthen their quality and make a product good-looking. What’s more, mechanical structures make possible the specific movement of a product. Gear, for example, does a lot help for the transmission in a typical machine. Up to now, there have been thousands of millions of different but ingenious mechanical structures invented by those talents in this field. It is those epoch-making mechanical structures that push human civilization into a glorious big time.
When it comes to electric, it’s like blood, which connects all the organs in a human body. Why would I say that? Let me tell you the reason. We know motor drives the machine to move. But what drives motor to move? The answer is electricity. Electricity flows throughout the machine and makes every “organ” alive. What a wonderful thing! Generally speaking, electric in machine designing includes circuit diagram, electronic components and electronic chip. Engineers draw circuit diagram, write programs into chips, and after that they put many components altogether to ensure the final situation follow their original designing.
After we understand the importance of structure and electric, let’s talk about simulation. Simulation is a certain particular process to imitate a model in virtual world. In the modern time, creating inventions in the computer and testing it after that definitely shortens the circle we manufacture a certain machine. Besides that, analysis to the virtual products is also available these days. Obviously, it is simpler to test a model in computer rather than in the real world. It will save a lot of money, right? All in all, what an essential and economic way simulation is and without it, we nearly can’t do anything effective today to create a product high in quality.
Now, you can see that structure, electric and simulation show their own essential role in the manufacturing. Works by engineer are not a secret job as we expected before. It’s just a process of applying one technique into making a product. That’s it! Wish all of you could enjoy it.
Thank you.
