The Intellectual Property Office of China recently authorized that the “Ship to Gate Wall Friction Test System†jointly declared by Hohai University, Nanjing Hohai Technology Co., Ltd. and Yangzhou Waterway Management Office of Jiangsu Province has obtained an invention patent. "Ship-to-lock wall friction test system" can accurately measure and record the contact time between the ship and the lock wall, and the dynamic changes of the friction force during the friction process. It has the characteristics of simple structure and easy manufacture, maintenance and use. This system, combined with finite element software simulation, can be used as a tool for the study of the frictional force of the ship against the gate wall, and provides a basis for the strength index and ratio of the concrete of the gate wall during the design, construction, maintenance and management of the gate. leather corner sofa,Corner Sofas,large corner sofa,corner chaise sofa Guangzhou LoPhiDa Co.Ltd , https://www.widinlsamachine.com
