DEVICE FOR SIMULATION OF NATURAL VANTE CHARACTERISTICS IN ELASTIC-FREE MODELS OF BRIDGES

摘要

The utility model relates to the field of modeling real objects in wind tunnels and can be used to simulate a guy on an elastic-like bridge model.;The purpose of the proposed utility model is to simulate stiffness and aerodynamic drag for the bridge guy model, as well as to simplify its design without compromising the main characteristics.;The problem is solved as follows. The device for modeling the characteristics of full-time guys in elastopodobnyh models of bridges, consisting of a span, a pylon, a cable and fasteners. Co-axially placed along the entire length of the cable are cylindrical elements whose diameter, length and quantity are selected so that the total aerodynamic drag of the cable and cylindrical elements is proportional to the aerodynamic resistance of the field guy for the selected scale; , so that the total stiffness when stretching the cable and the spring is proportional to the rigidity of the guy of the full-scale bridge for the selected scale . The tension spring can be located at the point where the cable is attached to the pylon.
