Study on Coupled Vibration of Human-plate System under Pedestrian Excitation
Lilin Cao,Niankang Wang,Chun-Hua Lu,Manicka Dhanasekar 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.4
In the paper, in order to explore the influence of human-structure interaction (HSI) in the vertical direction on the dynamic response of floors due to human-induced excitation, the formula for the human-plate interaction system is deduced. The pedestrian is in turn modelled as moving force (MF), spring-mass-damper (SMD), and added mass-spring-mass-damper (MSMD). The floor is modelled using a formulation in modal coordinates. Aiming at the formula of human-plate interaction system, the state space method is used to get the instantaneous frequency and instantaneous damping ratio of the floor under walking excitation, and the acceleration responses can be obtained using the Runge-Kutta method. Furthermore, this work studies the influence of pedestrian mass and structural modal mass on structural vibration response. The results show that the floor frequency is observed to decrease and the damping ratio gives the opposite trend when the pedestrian enters the floor. The MF model overestimates the measured response, while the actual results can be well approximated by the results for SMD and MSMD models considering HIS. Accounting for increasing human mass and decreasing modal mass lead to significant increase in the dynamic properties and the structural response.

Research on Construction of Enterprise Informatization based on Model of Multi-agent RigidFormation
Li Sun,Ying Liu,Qiang Qu,Lilin Ma,Guang Yang,Hu Cao 보안공학연구지원센터 2014 International Journal of Grid and Distributed Comp Vol.7 No.6
Enterprise informatization is a large system including: input, output, feedback, operation inside, executive action and incentive measures. Inner-enterprise can be seemed as an artificially social organization unit composing of various agents in a rigid formation. This paper mainly proposes an enterprise informatization associated with rigid formation theory of multi-agent. The connection between agents and enterprise factors is represented. The relationship between enterprise factors is described by potential function theory: the attractive force presents that all factors have the same opinion, and the repulsive force presents that all factors have the different opinion needed to be solved. Finally, the simulation proves that the model mentioned in this paper is effective.
