This paper introduces a scheme of constructing a three-dimensional container handling and distributing system between crane yard and storage yard for the efficient, smart, energy-saving automated container terminal (ACT). This scheme can effectively solve the problem that the AGVs in existing ACT should give way to each other in ground planer transportation mode, and has advantages of lower investment cost higher handling efficiency. The safety and running stationarity of the container vehicle-truss bridge structure greatly affects the ACT’s efficiency and lifespan. The assessment criteria for structural security and running stationarity was put forward first. By utilizing free-interface component mode synthesis (CMS) method, the coupled vibration time-domain responses, inspired by self-excitation including track irregularity and hunting movement as well as wind and seismic load, were obtained. Accordingly, the structural and running stationarity were assessed by indicators such as deflection-span ratio, vibration acceleration, wheel-rail relative displacement, suggesting a speed threshold of container vehicle under seismic and operational wind loads. The simulation and model test results also validate lead rubber bearing (LRB)’s effects on vibration isolation and absorption, thus can increase ground motion intensity and vehicle speed thresholds to structural safety.
