Abstract

Abstract

In order to explore the vibration dynamic performance of the gymnasium floor structure under complex excitation, a dynamic signal acquisition and analysis was used system to experimentally determine the speed response and energy distribution change rules of different distribution pilots of the gymnasium. The vibration characteristics under the excitation of single people and two people were summarized through experimental analysis. The energy distribution of each pilot site was affected by factors such as the supported constraints, different types of excitation modes, and the location of the loaded excitation. Among them, the excitations loaded in different distribution pilotss locations was the main factor which determined the law of energy distribution. Compared with different excitation types such as walking, jumping, dancing, and bouncing, jumping excitation had more input energy than bouncing excitation, so that the response of each pilot exhibited a more regular form of beat vibration. The energy was absorbed by the floor, showing a random structural dynamic response.
