摘　　要：跳台滑雪是运动员以滑雪板为工具,在曲线形态的跳台上完成规定动作的雪上竞技项目。在运动员的飞行过程中,垂直于运动方向的侧向气流会影响运动员的竞技水平甚至生命安全。因此,亟需一套针对跳台滑雪运动飞行段的气流防控装置设计方法。本研究以涞源国家跳台滑雪训练基地的跳台为研究对象,采用计算流体力学模拟技术进行气流防控装置方案设计,再对装置的结构方案进行验证。结果表明,设计方案解决了跳台滑雪赛道核心区风环境干预难的问题,能够将飞行段侧向气流速度控制在4m/s内,保障运动员的比赛安全。Ski jumping is a sport in which athletes use skis as a tool to perform prescribed movements on a curvilinear platform.In the course of the athlete’s flight,the lateral airflow perpendicular to the movement direction can affect the athlete’s competitive level and even their life safety.Therefore,there is an urgent need for a design method of designing airflow control device for the flight phase of ski jumping.This study takes the platform of Laiyuan National Ski Jumping Training Base as the research object,uses computational fluid dynamics simulation technology to design the airflow control device scheme,and validates the structural solution of the device.The results show that the design scheme solves the difficult problem of wind environment intervention in the core area of ski jumping track,and can control the lateral airflow in the flight phase within 4m/s to ensure the safety of athletes.
