Study on Real-Time Simulation Analysis and Inverse Analysis System for Temperature and Stress of Concrete Dam

In the concrete dam construction, it is very necessary to strengthen the real-time monitoring and scientific management of concrete temperature control. This paper constructs the analysis and inverse analysis system of temperature stress simulation, which is based on various useful data collected in real time in the process of concrete construction. The system can produce automatically data file of temperature and stress calculation and then achieve the remote real-time simulation calculation of temperature stress by using high performance computing techniques, so the inverse analysis can be carried out based on a basis of monitoring data in the database; it fulfills the automatic feedback calculation according to the error requirement and generates the corresponding curve and chart after the automatic processing and analysis of corresponding results. The system realizes the automation and intellectualization of complex data analysis and preparation work in simulation process and complex data adjustment in the inverse analysis process, which can facilitate the real-time tracking simulation and feedback analysis of concrete temperature stress in construction process and enable you to discover problems timely, take measures timely, and adjust construction scheme and can well instruct you how to ensure project quality

Web-based 3D Interactive Virtual Control Laboratory Based on NCSLab Framework

In this paper, the design and implementation of a web-based 3D virtual control laboratory with user interaction is introduced. The proposed system is based on NCSLab framework which has a six-tier distributed structure. Users are able to access diversely located resources through a unified user interface. In order to maximum the users’ sense of immersion during the virtual experiments, the 3D models of the practical test rigs are reconstructed in the users’ web-browsers. The 3D images are synchronized with the remote real-time simulation on the server side through the internet data link, so the users are able to sense how the experiment procedures are going on. Moreover, the users are also allowed to interact with the virtual devices. They can operate on the virtual test rigs using the mice and keyboards like turning on/off a switch and changing the valve positions etc. These interactivities are uploaded to the server side where the corresponding internal parameters are updated automatically. The system implementation and deployment such as the 3D web-based interface, 3D modelling, mathematical modelling and internet based communication among the clients, servers and control units are explained in details. To illustrate how a given experimental process is integrated in the system, a classic coupled tank test rig is selected as an example at the end of the paper
