Publication number: 20240093373Abstract: A method for preparing antibacterial stainless steel by surface alloying includes the steps of coating an infiltration promoter layer on a stainless steel surface, coating an antibacterial metal layer on a surface of the infiltration promoter layer, and performing heat treatment of the stainless steel to diffuse an antibacterial metal into the stainless steel. This method can be applied to various types of stainless steel, and the antibacterial metal can be diffused and quenched into the stainless steel, such that the finally formed surface of the stainless steel has an antibacterial alloy layer with a specific thickness to provide better corrosion resistance and antibacterial ability without changing the advantages and properties of the antibacterial metal or stainless steel substrate, and the thickness and concentration of the antibacterial metal layer, and the parameters for heat treatment can be adjusted to control the chemical composition and thickness of the antibacterial alloy layer.Type: ApplicationFiled: November 16, 2022Publication date: March 21, 2024Inventors: WEN-TA TSAI, BERNARD HAOCHIH LIU, ZHI-YAN CHEN, CHONG-CHENG HUANG

Patent number: 9785730Abstract: The present invention discloses a simulated loading method and an apparatus for moving load of a whole train in rail transportation. Multiple actuators are arranged above rail sleepers along rail direction. The rail is cut into separate rail segments, which are connected to rail sleepers via fastening systems. Based on a verified train-rail-subgrade theory model, the distribution of fastener force under the movement of a train bogie can be obtained. A simplified expression of this solution can be acquired by Gauss function fitting considering the train axle load, which is used as the input load of actuators. Each actuator performs the same dynamic excitation sequentially with a time interval along the train moving direction. Therefore, moving load of different vehicle types at different train speeds can be simulated. The present invention provides a reliable and convenient test method and an apparatus for research of developing infrastructures of rail transportation.Type: GrantFiled: June 6, 2014Date of Patent: October 10, 2017Assignee: ZHEJIANG UNIVERSITYInventors: Yunmin Chen, Xuecheng Bian, Hongguang Jiang, Jianqun Jiang, Chong Cheng, Renpeng Chen, Xiang Xu, Wanfeng Jin

Patent number: 9747395Abstract: The present invention discloses a simulated loading method and an apparatus for moving load of a wheel axle in rail transportation. Multiple actuators are arranged right above rail sleepers along rail direction. The two continuous rails are connected to the rail sleepers via fastening systems and are cut into discrete independent rail segments right above the rail sleeper. The anti-drop member satisfies the applications of compression and uplift force of the actuator. The input load of each actuator is obtained from the load-time history of a single fastening system under moving load of a wheel axle according to a train-rail-subgrade theory model, and adjacent actuators perform dynamic excitation in turn with a same time interval to achieve simulation of moving load of a wheel axle under different speed. This invention provides a reliable and convenient loading platform for experimental study of the rail transportation.Type: GrantFiled: June 6, 2014Date of Patent: August 29, 2017Assignee: ZHEJIANG UNIVERSITYInventors: Xuecheng Bian, Hongguang Jiang, Yunmin Chen, Chong Cheng, Jianqun Jiang, Xiang Xu, Renpeng Chen, Wanfeng Jin
