一、 Study Object

There are vast numbers of different kind

s of machines in the world, all with a wide var

iety of constructions, characteristics and uses.

Internal Combustion Engine .

Mechanism is a system of links which c

an transform or transmit force and motion.

§§11 －－ 1 1 Study Object and ContentStudy Object and Content

Machine is a mechanical system that can transmit or transform

energy, materials or information.

The term" machinery" is used to cover both mechanisms and

machines. The study object of this book is machinery.

many practical machines contain more than one mechanism while

many simple machines are composed of only one basic mechanism.

Internal Combustion Engine: slider-crank mechanism + cam

mechanism + gear mechanism.

二、 Study Content

1. Fundamental Knowledge for Mechanism Structure

Analysis

2. Movement Analysis of Mechanisms

3. Dynamics of Machines

4. Study of Commonly Used Mechanisms

The main content of this course includes following four aspects:

This textbook "Mechanisms and Machine Theory" is an aid t

o the study of machines and mechanisms. It is hoped that, after st

udying this textbook, the students will grasp the basic theory and

obtain the basic knowledge and skills needed in mechanisms synth

esis and kinematic and dynamic analysis of machinery. This shoul

d lead to the ability to choose machinery motion patterns, analyze

and synthesize mechanisms and develop designs for practical wor

king machinery. The knowledge to be obtained from this textbook

is therefore a fundamental in analyzing existing machines and des

igning new ones.
