报告题目：Modeling and simulation of the dynamic response of rigid bodies on a moving base
报告摘要：
This is often referred to as the rocking problem in earthquake engineering and has been considered since the 1960’s in the seminal work of Housner. Recent research results will be presented which include previously unaddressed phenomena which are critical to the overall dynamical performance and have heretofore not been considered in combination: 1) 3-dimensional modeling, 2) interface friction, 3) bouncing and 4) the inclusion of geometric nonlinearities. The simulation models developed have implications in a variety of application areas such as seismic vulnerability of the toppling of non-structural objects such as electrical transformers, computer server racks and ancient stone monuments. In addition, the 3-dimensional models have been enhanced to include wheels, so that cart systems such as those commonly found in hospitals may also be considered.
