Fundamentals of machine design

via XuetangX

Overview

Dear Students,

 

Hello everyone! Welcome to the "Fundamentals of Mechanical Design" class. I am very pleased to meet you here and have the opportunity to explore the vast world of mechanical design together.

 

How is mechanical transmission motion transmitted in machines? How is steering achieved in automobiles? How are mechanical parts designed and calculated? If you want to know the answers to these questions, please join our course!

 

The main focus of this course is mechanisms. We will cover the composition and structure of mechanisms, the analysis and design of commonly used mechanisms, the structure, characteristics, and design methods of commonly used mechanical parts. Through this course, you will learn the basic knowledge and theories of common planar mechanisms, general mechanical components, and mechanical transmission devices. You will become familiar with the general methods and principles of mechanical design, acquire the ability to design common planar mechanisms, master the design methods of general components, and have the initial ability to design mechanical transmission devices and simple machines. You will also gain the ability to use standards, manuals, atlases, and technical resources, and develop an understanding of the development trends and directions in mechanical design.

 

"Fundamentals of Mechanical Design" is an important transition point from highly theoretical and systematic foundational and specialized courses to more practical professional courses. It plays a connecting role in the curriculum, and the level of knowledge mastery in this course directly affects the learning of subsequent courses. It is a core course for students to acquire basic professional skills. Mastering this course will lay a solid foundation for you to obtain the professional qualifications needed for positions in product design, product processing, inspection, and equipment maintenance in the future.

 

Our teaching team for this course includes experienced professors, nationally recognized young technical experts, and doctors with solid theoretical knowledge. They will use humorous, lively, and engaging teaching methods to help you rediscover the "dry and tedious" mechanics and explore the philosophy of life within machinery. Here, mechanics are no longer dull or obscure. Let's enjoy the charm of mechanics together!
