[Abstract]:The design of the supporting panel is an integral part of the design of the curling track platform. The platform supporting structure composed of the supporting panel and the lower supporting steel frame is the key part of whether the curling field can meet the WCF track standard. The supporting structure not only needs simple design, clear transmission, convenient assembly, but also has a very high target for the vertical natural vibration frequency of the platform supporting structure in order to meet the requirements of the comfort of various events. In addition, during the later maintenance of the curling track, the maximum settlement of the ice surface needs to be controlled in order to enable the ice supporting structure to withstand the wheel compression load of the large ice pouring vehicle. In this paper, the method of test and finite element simulation is used to design and optimize the ice bearing structure, and the settlement and vertical natural vibration frequency of different bearing panels are studied. At the same time, the mechanical properties of different supporting structures and the joint connection performance of the supporting frame are also studied. The main contents are as follows: 1. The primary design of the water cupping field of the Water Cube Olympic Games can be divided into four parts: the supporting frame, the panel unit, the connection between the components and so on. The panel element is designed as a ribbed wooden box filled with extruded plastic board, and the internal structure and material properties are studied in depth. The static load test of the panel element is carried out under many working conditions, and the bearing capacity of the panel element is obtained. The key indexes of stiffness and failure mode are analyzed by Abaqus finite element program. The optimization scheme is proposed, which proves that the proposed panel element has sufficient stiffness and bearing capacity, and can provide an effective support for the ice surface of the curling course. 3. Based on the proposed ice support scheme, An overall field test of the detachable curling field was completed in the Water Cube Pool. The test is divided into six stages, including the measurement of the stiffness, bearing capacity, long-term deformation, frequency, acceleration and other dynamic characteristics of the support frame, the supporting panel and the ice sheet. It is verified that the proposed overall support scheme can meet the requirements of the ice ball match of the Winter Olympics. Using Abaqus finite element program, the overall field test results are numerically simulated. Furthermore, the maximum vertical displacement and the first order natural vibration frequency of the ice supporting structure under the 300kg load of curling players are analyzed. In particular, the maximum vertical displacement and the internal stress level of the ice bearing structure under the pressure load of the large ice-pouring wheel are deeply analyzed.
