LOADS GENERATED BY HUMAN JUMPING:EXPERIMENTS AND NUMERICAL MODELING

摘要：

　　The load curves of 100 test subjects jumping at five different rates have been measured using three-dimensional motion capture technique in conjunction with fixed force plates.The variation ranges and statistical properties of the three key load parameters:jumping frequency,impact factor and contact ratio are investigated based on the test results.A modified half-sine-power load model is proposed to simulate the jumping load,in which the jumping frequency and contact ratio are independent parameters whilst the impact factor needs to be determined by frequency and contact ratio.The applicability and feasibility of the proposed model has been validated by comparison of the simulated load curve with measured curve and by comparison of the acceleration response of single degree of freedom system subjected to the simulated and measured jumping load.The results prove that the suggested model can be adopted for vibration serviceability assessment of large span structures.
