As high-level talents,graduate students play an important role in the process of improving the innovation ability of China's equipment manufacturing industry.At present,the scale of postgraduate enrollment in China is expanding day by day,but at the same time,the quality of postgraduate training is difficult to fully meet the social needs.Based on the basic concept of new engineering,this paper explores the improvement of the innovation ability of mechanical graduate students from several aspects,such as the construction of the curriculum system,the construction of the training mode of"multi-teacher system",and the construction of the joint training base.The results of postgraduate training in recent years show that the proposed method has a significant role in promoting postgraduate innovation ability.In the future,it can be extended to other relevant majors according to the characteristics of the major,which can provide reference for improving the innovation ability of graduate students.
