Patent number: 11891573Abstract: A method and device for controlling viscosity of asphalt rubber based on a current variation are provided. The method includes processing asphalt rubber raw materials with a first preset proportion, and shearing the processed asphalt rubber; obtaining a shearing current, pumping and discharging the sheared asphalt rubber; obtaining a discharging current, and obtaining the viscosity of the pumped asphalt rubber according to the discharging current and the viscosity-discharging current correlation relationship. The method includes comparing the viscosity with a preset viscosity; outputting the pumped asphalt rubber as finished asphalt rubber when the viscosity is equal to the preset viscosity. The method includes adjusting the viscosity according to the discharging current. Double-current control is adopted, so that the whole-process control of the processing viscosity of the asphalt rubber is realized, and the control accuracy of the viscosity is improved.Type: GrantFiled: February 25, 2022Date of Patent: February 6, 2024Assignees: GUANGXI TRANSPORTATION SCIENCE AND TECHNOLOGY GROUP CO., LTD., GUANGXI JIAOKE NEW MATERIALS TECHNOLOGY CO., LTD.Inventors: Honggang Zhang, Hongbo Zhang, Haitao Yuan, Jizong Tan, Baolin Xiong, Yong Wang, Jianchun Yan, Yehao Yin, Xiaolei Wang

Publication number: 20230145543Abstract: The present disclosure provides a method for static identification of damage to a simply supported beam under an uncertain load. In this identification method, a beam body is first segmented, and the relationships between key measured sectional rotation angles and the flexural rigidities of segments of a structure under the action of a load are established by using a mechanics principle; then, an applied static load is removed by means of a division operation, and the relative relationships between the flexural rigidities of the segments of the structure are obtained; and finally, these relative relationships are compared with the corresponding relative relationships when the structure is not damaged, so as to determine the position of damage to the structure and assess the amount of damage, such that the static identification for damage to a simply supported beam structure can be completed without calibrating a load in advance.Type: ApplicationFiled: October 27, 2020Publication date: May 11, 2023Applicants: GUANGXI TRANSPORTATION SCIENCE AND TECHNOLOGY GROUP CO., LTD., GUANGXI FARMS AGRIBUSINESS DESIGN ACADEMYInventors: Yuhou YANG, Xian MA, Xiaoli ZHUO, Longlin WANG, Mengsheng YU, Hua WANG, Shijian LIU, Yucai JU, Xi PENG, Yihao NING
