Research Fields

Centering on the new technology laser processing, the laboratory aims at solving the major engineering problems of many great projects including offshore engineering equipment, new energy equipment, iron & teal metallurgical equipment, petroleum machinery equipment, wind power & nuclear power equipment, aeronautics & astronautics, automobile, military equipment. The theories and technologies of advanced manufacturing by laser have been studied, and the achievements of our research make great contributions to many fields. For example, settling the problems of the remanufacturing of damaged high added value parts and the anti-fatigue safety of critical equipments serves to the circular economy and energy & resource conservation; settling the problems of the punching of holes at high-strain state satisfies the safety demanding of airplane’s structure; settling the problems of the light-weight of automobiles contributes to the reduction of energy consumption. We are committed to promote the development of advanced manufacturing technology in our country. To gradually narrow the technical gap between ours and the most advanced in the world, we will accelerate the process of research and engineering applications of the advanced manufacturing technology by laser and improve the overall level, the ability to competition and the ability of innovation of our manufacturing industry.

Through many years’ efforts, we have established seven major research ordinations in this field:

Advanced Manufacturing Theory & Technology using Intense Laser based on Mechanical Effect from Laser Shock.

  • ? Measurement of Physical Properties of Interface using Laser.
  • ? Surface Modification and Life Prolonging using Laser.
  • ? Optoelectronic Material & Advanced Manufacturing Technology of Components and Devices.
  • ? Advanced Forming Technology based on Laser Tailor-weld of Sheet.
  • ? Manufacturing Theories & Technology at Floating State.
  • ? Critical Technology for Skid-mounted Fueling Station of LNG Vehicles.

Team Members

Lab is a research team which has rigorous scientific research style, has the spirit of dedication and has reasonable level and age structure. There are 39 fixed researchers in the team, including 10 tutors, 18 professors, 11 associate professors. The team got outstanding discipline echelon of the Jiangsu Province. One of the teammates was chosen as the century leader in the field of Jiangsu province. Six of the teammates were chosen as 333 training person of Jiangsu province. The team owns over 20 doctoral candidates and 70 master's degrees candidates, and has formed a rational structure study team which has the spirit of the unity cooperation. In 2002, the team was evaluated excellent discipline echelon of “youth project” in Jiangsu province higher school. In 2003, the team was approved for mechanical engineering demonstration base of Jiangsu province which is the combination of production, learning and studying for graduating students. In 2008 the team got the first science and technology innovation team of the Jiangsu University
