Liu Yonghong's main achievements

As the person in charge, he has completed more than national and provincial projects 10, and 3 scientific and technological achievements are at the international leading level; Innovative research results have been achieved in the technical and theoretical research of EDM of non-conductive difficult-to-machine materials, plasma machining of micro-composite cavity slot screen and EDM of curved holes. The dual-electrode synchronous servo tracking EDM grinding technology for non-conductive and difficult-to-machine materials is proposed for the first time. Take the lead in developing micro composite slotted screen pipe and its plasma processing technology, and promote its application at home and abroad, creating direct economic benefits of more than 654.38 billion yuan; In this paper, a new method of developing a curved hole EDM robot by using shape memory alloy functional materials and imitating the bending and crawling principles of mollusks such as earthworms is proposed. The EDM technology is creatively introduced into oil well orifice to unblock and make cracks, which broadens the application field of EDM technology. Ranked 1, won 2 second prizes and 6 third prizes for provincial and ministerial scientific and technological achievements, 2 first prizes and 2 second prizes at bureau level 1; Published more than 20 academic papers 120 (including more than 40 articles included in SCI and EI); Ranked 1, authorized 6 invention patents, accepted invention patents 1 1.

At present, as the project leader, he is undertaking 2 national natural science foundation projects, 2 1 863 projects and 2 provincial and ministerial projects.
