Wind tunnel aeroelastic tests of full bridge reduced models are nowadays a mandatory step in the design of long-span bridges. The tests require complex, timedemanding and expensive experimental campaigns which consequently increase the costs of the projects. These campaigns consist of a long list of tasks, which includes wind characterization, model design and construction, instrumentation calibration, data acquisition and post-processing of the acquired data, among others. Thus, advances in any of these activities will always represent a technical advance in terms of test performance and economical efficiency. This paper focuses on the model design, and a brief description of the whole process is presented. Besides, the design process was implemented in an integrated software and it is presented with an application example of a generic cable-stayed bridge deck. The software allows the design of the whole reduced model in a user friendly way and in a very short working time.
This paper is based on completed the design of the main structure of the fumigation treatment bed according to the size of the human body’s structure. And the solid modeling of each part is carried out in the CATIA environment. Then the working process of the fumigation bed is simulated by using the virtual prototype module of CATIA software. Using the FLUENT flow field analysis software to analyze the temperature field and velocity field of the fumigation tank’s inward under different conditions. With setting different variables in each condition gradually optimize the temperature field and velocity field in the fumigation tank’s inward.
