摘要:北京2022年冬奥会和冬残奥会场外火炬台由雕塑造型工程、双转台装置、燃料供应和燃烧系统等组成。雕塑造型工程作为火炬台核心部件,为达到艺术效果,整体轮廓呈大跨度多曲面异形风敏感结构,采用风洞试验方法获取整体结构的风振系数和体型系数。雕塑造型工程作为永久性建筑和动态雕塑,结合其运动特征确定了两种计算工况,两种计算工况分别综合考虑自重、风荷载、地震作用、雪荷载和温度作用等,按照规范对各类荷载进行叠加,采用有限元计算方法对结构整体进行强度和刚度计算和校核,确保场外火炬台在极限工况下安全、可靠。同时,工程结构局部位置的变形逐渐加大将影响装置转动,最终采用方案是风速超过8级风时,火炬台不能转动,需要关停机械装置,待风速降低后再使用。

Abstract: Beijing 2022 Olympic Winter Games and Winter Paralympic Games cauldron outside National Stadium is composed of sculpture modeling engineering, double turntable device, fuel supply and combustion system, etc. As the core component of the cauldron, the sculpture modeling engineering presents a large-span multi curved surface special-shaped wind sensitive structure in order to achieve artistic effect. The wind vibration coefficient and shape coefficient were obtained by wind tunnel test. As a permanent building and dynamic sculpture, sculpture modeling engineering determines two calculation cases based on its motion characteristics. Two calculation cases comprehensively consider the self-weight, wind load, earthquake action, snow load and temperature action, superimposes each load according to the specifications, and calculates and checks the strength and stiffness of the whole structure by using the finite element calculation method, so as to ensure the safe and reliability of the cauldron under the limit case. At the same time, increasing local deformation of the engineering structure will affect the rotation of the device. The final solution is when the wind speed exceeds grade 8, the cauldron could not be rotated, so the mechanical device needs to be shut down and used again after the wind speed is reduced.
