In the drawing, using CAXA software, improved work efficiency. In the threedimensional modeling, using Pro / ENGINEER software, pleted the modeling work of Pistons entity、 piston rings and piston pin, and timely discovery the errors of structure design. In terms of curriculum design process, through access to relevant information, Mastered the piston design of the initial steps and methods. In the course of find informations, profoundly understand the importance of books searchable, in explore practice set a own’s information retrieval methods. At the same time, also familiar with the major professional and technical forums. Piston design involved a broader range of knowledge, needed in a good grasp of engineering materials, mechanics of materials, engine principle, engineering thermodynamics, machining and automotive structural and so on. On basis of such courses to better plete the design task. At the same time, for a variety of software proficiency is also very necessary. Through the curriculum design, gives me a more prehensive review of knowledge I have knowled, help to find own’s inadequacies. Aware of the knowledge structure of engineering materials and engineering thermodynamics aspects of myself’s is more shallow, the actualputing power is very poor, urgent need to strengthen. In access to information, there is obviously insufficient, especially on the inspection of foreignlanguage information, it is unable to.
