"Textile Light" Applied Basic Research Two Project Through Acceptance Check

In December 24, 2019, Experts from the Ministry of science and technology development of China Federation of textile industry Undertaken by Donghua University in Shanghai Research on the key technologies of the master slave control ring spindle electrical spindle system Sum Research on dynamic characteristics of parametric frequency varying high speed winder in full cycle production process Acceptance check. ? Deputy Department of technology development director Zhang Huiqin, Secretary General of textile optical technology education foundation, Zhang Cuizhu Attendance Meeting 。 The acceptance expert group heard the report of two projects, reviewed relevant information, and questioned and discussed that the two projects had completed the requirements stipulated in the task document, and agreed to accept the conclusion.

Research on Key Technologies of master slave control ring spindle electrical spindle system Taking the electrical spindle system of ring spinning frame as the object, this paper focuses on the realization method of high efficiency and low cost motor drive motor and its control system, develops a high efficiency and low cost drive motor of hollow cup motor and two control systems, puts forward the theoretical analysis model of the vibration characteristics of the electric spindle, develops a testing system for the vibration characteristics of the spindle based on image processing technology, and develops the mechanical characteristics of the motor. Test platform. The project laid a technical foundation for the research and application of the ingot motor and its control system. During the implementation of the project, 13 papers were published, 6 patent applications were granted, 4 were authorized, and 9 postgraduate students were trained.
