Objective: To investigate the transmissibility of the swing and the vertical vibration in human lower limb with three postures, eg. the knee lock ,knee angle loek and knee normal conditions.
Methods: The swing and vertical vibrations were added on the subject’s foot segments and then the points on the calcaneus, lateral malleolus, tibial lateral condyle and fumer lateral condyle were monitored when the subjerts were with 3 postures. The phase difference correcting Methods of discrete spectrum which were widely used in rotor dynamics analysis were applied in the transmissibility analysis. The transmissibility and energy distribution of marked points on the lower limb with three postures during swing and vertical vibrating process were obtained.
Results: It was indicated that the vertical vibration accelerations of marked points in the subject’s lower limbs were greater with same postures than those of swing vibration. And the transmissibility ratios of those marked point of vertical vibration were a litter greater than those of swing vibration. Also the vertical vibration transmissibility was steadier than the swings’.
