EIS evaluation of steady-State Characteristic of 316L stainless steel passive film grown in acidic solution
Electrochemistry Communications, 2013Co-Authors: C. Boissy, Catherine Alemany-Dumont, Bernard NormandAbstract:The EIS is a useful tool to characterize corrosion behavior of stainless steel, especially when it comes to the properties of the passive film. A specific electrical equivalent circuit was therefore developed to investigate the diffusion/migration of vacancies occurring within this oxide as described in the point defect model. This circuit was used at 20 C, 60 C and 80 C. The vacancy diffusion coefficient calculated was found to be close to 10- 14cm2s- 1. © 2012 Elsevier B.V. All rights reserved.

Emulation of Steady-State Characteristic for Water Hydraulic Proportional Throttle Valve
Machine Tool & Hydraulics, 2020Co-Authors: Sun ShuwenAbstract:The structure and feature of a new water hydraulic proportional throttle valve were introduced,and its simulation model of steady-State control Characteristic,flow Characteristic and load Characteristic were established,main factors influencing steady-State Characteristic were determined through simulation analysis with software MATLAB/SIMULINK,and some steady-State Characteristic indexes such as displacement initial current,flow initial current,dead zone and hysteresis and other indicators were determined.The analysis shows that spool displacement has a good linear relation with input current,and that the output flow of water proportional throttle valve is related to type of valve port,and is affected by working pressure difference.In order to gain better steady-State Characteristic,the working pressure difference of valve port should be compensated or closed-loop control should be adopted.

Analysis and emulation of steady-State Characteristic for water hydraulic proportional throttle valve
2009 IEEE 10th International Conference on Computer-Aided Industrial Design & Conceptual Design, 2009Co-Authors: Wang Xinhua, Chang Jiaqing, Wen Yanjie, Zheng Jian, Sun ShuwenAbstract:A new type of water hydraulic proportional throttle valve is designed. The mathematical models of steady-State control Characteristic, flow Characteristic and load Characteristic for the new designed water hydraulic proportional throttle valve are established, in addition some main factors influencing steady-State Characteristic are determined, and some steady-State Characteristic analysis such as displacement initial current, flow initial current, dead zone and hysteresis and other Characteristic is also proceeded. The analysis and emulation show that spool displacement has a good linear relation with input current, and that the output flow of water proportional throttle valve is not only related to type of valve port, but also affected by working pressure difference. In order to gain better steady-State Characteristic, the working pressure difference of valve port should be compensated or closed-loop control should be adopted. The result is of great instructive significance for optimizing design parameters of the water hydraulic proportional throttle valve, analyzing dynamic Characteristic and designing control system.
