The education based on CDIO is an advanced education idea,which develops team spirit and improves practical ability.Hydraulic & pneumatic is a strong practical course.Remarkable effect can be achieved by using the CDIO theory in hydraulic & pneumatic teaching.The opening simulation experiment system was established through using German FESTO company's pneumatic teaching platform and hydraulic & pneumatic simulation software—FluidSIM.The experimental team was composed of 3~6 students.They could be free to design experiments by using the simulation experiment system and solve all problems independently.Thus the CDIO training goal is achieved.
