Design and Implementation of Strain Strengthening Automation Control System for Austenitic Stainless Steel Pressure Vessels

摘要

According to the technology requirements of strain strengthening, hardware instruments, such as upper computer, PLC, A/D converter, D/A converter, frequency converter, sensors and software components such as configure software, PLC programming software were adopted to design and develop a strain strengthening automation system for austenitic stainless steel pressure vessels. The automation system can realize a wide range of functions such as control program loading, data acquisition, strain strengthening process monitoring, experiment data saving and printing, pressurization rates controlling as well as measurements of radial strain and residual volumetric deformation. The actual practice shows the system has characteristic of running stabilization, high control accuracy, high-degree security and having the ability of automation control for strain strengthening process.
