Course Target Participants: Third-year undergraduates in Specialty of Mechanical Engineering and Mechat

2、ronics Engineering5. Course Type: Foundation course of the discipline （Compulsory）6. Teaching Mode: Multimedia + Bilingual teaching7. Course Features and Aims:The objective of this course is to provide the concepts, procedures, data, and decision analysis techniques necessary to design machine eleme

3、nts commonly found in mechanical devices and systems. Students completing a course of study using this course should be able to execute original designs for machine elements and integrate the elements into a system composed of several elements.This process requires a consideration of the performance

4、 requirements of an individual element and of the interfaces between elementsas they work together to form a system. For example, a gear must be designed to transmit power at a given speed. The design must specify the number of teeth, pitch, tooth form, face width, pitch diameter, material, and meth

5、od of heat treatment. But the gear design also affects, and is affected by, the mating gear, the shaft carrying the gear, and the environment in which it is to operate. Furthermore, the shaft must be supported by bearings, which must be contained in a housing. Thus, the designer should keep the comp

6、lete system in mind while designing each individual element. This course will help the student approach design problems in this way.This course is designed for students for mechanical engineering or so. The emphasis is on the use of readily available materials and processesand appropriate design app

7、roachesto achieve a safe, efficient design. It is assumedthat the person using the course will be the designer, that is, the person responsible for determining the configuration of a machine or a part of a machine. Where practical, all design equations, data, and procedures needed to make design dec
