摘要：2022北京冬奥会带动了我国冰雪运动及场馆设施的快速发展，首钢滑雪大跳台是全球第一个城市中建成的永久跳台。根据单板滑雪大跳台赛道曲线和自由式滑雪空中技巧赛道曲线的特征，研究了赛道转换的可能性和各种转换方式；发明了一种正四面体模块及正四面体连接节点，提出了针对首钢滑雪大跳台的模块化赛道转换方式；通过首钢滑雪大跳台示范工程的建设，首次实现了单板滑雪大跳台和自由式滑雪空中技巧两项比赛的模块化转换及共享，大大降低了建设两条赛道的成本。模块化的赛道转换技术遵从了标准化、工业化的基本原则，具有易安装、适应性强、安全可靠、易储存的特点，也和当今建筑行业工业化的发展方向是一致的，具有继续拓展研发、推广应用于更多场景的价值。

Research on conversion design of regular tetrahedron modular track of Shougang Snowboarding Platform
Abstract: The 2022 Beijing Olympic Winter Games has driven the rapid development of ice and snow sports and venue facilities in China, Shougang Snowboarding Platform is the first permanent platform built in a city in the world. According to the characteristics of the track curve of big air and aerials freestyle, the possibility of track conversion and various conversion methods were studied; a regular tetrahedral module and regular tetrahedral connection node were invented, and a modular track conversion mode for Shougang Snowboarding Platform was proposed; through the construction of Shougang Snowboarding Platform demonstration project, the modular conversion and sharing of big air and aerials freestyle competitions have been realized for the first time, greatly reducing the cost of building two tracks. The modular track conversion technology complies with the basic principles of standardization and industrialization. It has the characteristics of easy installation, strong adaptability, safety, reliability and easy storage. It is also consistent with the development direction of current industrialization of the construction industry, and has the value of continuing to expand research and develop, promote and apply to more scenes.
Keywords: Shougang Snowboarding Platform; regular tetrahedral module; regular tetrahedral connection node; modular track conversion system; 2022 Beijing Olympic Winter Games
