摘要

Bounce指音乐会或体育比赛中常见的观众双脚不离地的身体有节奏的上下往复运动。利用测力板以及无线测力鞋垫,开展了单人在不同频率下的bounce荷载的测试实验,共得到了109人次822条有效单人bounce荷载记录。在此基础上,建立了Bounce荷载的傅里叶级数模型,给出了四阶动载因子和相位角的建议值,并与国外已有模型进行了对比分析。本文模型所模拟的Bounce荷载与实测荷载的时域特性相同,所引起的结构响应幅值一致,可供工程设计参考使用。

Abstract

Bounce refers to the up-down movement of human body with two feet remaining on the ground, which is a typical activity of audience in a concert or sport game. This study carried out experiments to test the single person’s bouncing load under different frequency using force plates and wireless dynamometer insole. One hundred and nine test subjects participated in the experiments resulting in 822 individual bouncing load records. A fourth-order Fourier series model was suggested to represent the bounce load, whose coefficients and phase angles were determined by statistical analysis on the experimental records. The proposed model was compared with other available models in terms of model parameters and time domain. Simulated bounce load curves by the suggested model had similar shapes as the measured loads. Meanwhile, the response of a single-degree-freedom-system to simulated and measured bounce loads were nearly the same.
