- An efficient, smart, energy-saving automated container terminal (ACT) scheme is introduced in this paper, in which one three-dimensional container distribution system is proposed between crane yard and storage yard. In this scheme, container vehicle-low bridge coupled vibration greatly affects the ACT’s structural safety and handling efficiency. Firstly, the coupled vibration time-domain responses, inspired by self-excitation including track irregularity and hunting movement as well as environmental (wind and seismic) load, were obtained by using free-interface component mode synthesis (CMS) method. The relationship of response and vehicle speed, wind velocity and ground motion intensity was studied as well. Accordingly, the structural safety, running safety and stationarity were assessed by indicators such as deflection-span ratio, vibration acceleration, wheel-rail relative displacement, etc. The container vehicle speed limits of the low bridge rigid supported or lead rubber bearing (LRB) supported under seismic and operational wind load were compared. The results of model test and prototype simulation prove with each other, which validates LRB’s effects on vibration isolation and absorption, thus can increase ground motion intensity and vehicle speed thresholds to structural safety.
