Patent number: 11403446Abstract: The invention discloses a method for predicting a residual strength of a composite material after impact. The method includes: acquiring a first frequency value of a composite material to be tested after impact damage; determining a first frequency change rate according to an initial frequency value and the first frequency value of the composite material to be tested; inputting the first frequency change rate to a pre-constructed residual strength prediction model to predict a first residual strength of the composite material to be tested; the first frequency value and the initial frequency value being obtained by a modal test. Further, residual strength prediction may be performed on the composite material in service, the position and the size of impact damage, the impact energy, the shape and quality of the impact object are not required to be determined, which avoids a rigidity test of the composite material in service.Type: GrantFiled: September 10, 2021Date of Patent: August 2, 2022Assignee: GUANGZHOU UNIVERSITYInventors: Zhifang Zhang, Jingwen Pan, Jiyang Fu, Airong Liu, Jiurong Wu

Patent number: 11009528Abstract: A system for measuring a cathode current includes a conducting bar and a current measuring device. The conducting bar has a rectangular plate-like structure, and a first end of the conducting bar is vertically cut to form a plurality of long teeth. The plurality of long teeth are equally spaced at the first end of the conducting bar. The number of the plurality of long teeth is equal to the number of cathodes. The upper surface of each of the long teeth may include a raised conductive contact. Each of the conductive contacts is connected with one cathode of an upstream slot. A second end of the conducting bar is connected with a downstream slot, and the second end of the conducting bar is one end opposite to the first end. The current measuring device is disposed on the conducting bar and used for measuring the current of each cathode.Type: GrantFiled: June 27, 2018Date of Patent: May 18, 2021Assignee: North China University of TechnologyInventors: Jun Tie, Rentao Zhao, Zhifang Zhang, Wentang Zheng
