用振动试验方法测定羽毛球拍杆的刚度

摘要

将羽毛球拍杆简化为单自由度弹簧质量系统,用振动试验方法测出系统的固有频率,用于计算羽毛球拍杆的抗弯刚度,并以此作为评定羽毛球拍杆软硬度的指标.振动试验方法方便、准确,可用于代替现行弹性测试法,作为测定羽毛球拍杆软硬度的标准.%In this paper, a vibration testing method to determine the stiffness of the badminton rod is presented. The badminton rod is simplified as a mass-spring system of a single degree of freedom, the natural frequency of which is measured by the vibration testing method. Then the stiffness parameter of the rod can be calculated by the frequency formula. The suggested vibration testing method is more convenient and accurate than the current flexible test method, and can be used as a standard method of judging the soft and hard degree of a badminton rod.
