Dynamic‐Behavior Modeler for Material Handling in Construction

This paper presents a conceptual dynamic‐behavior modeler for material‐handling equipment in construction. The dynamic‐behavior modeler provides a novel approach to modeling the motion planning process for engineers and constructors to allow for animation of the material‐handling process based on dynamic simulation. This will provide for better planning, modeling, and controlling of the material‐handling process. The modeler is intended to perform dynamic simulation of three‐dimensional (3D) rigid bodies for computer animation, and to model and predict real‐life behavior of physical objects subject to dynamic loading. This paper also presents a sample‐animation case involving a mobile crane in a pick and place task. The animation provides insight to the realistic visualization that would be achieved through dynamic simulation. To achieve real‐time animation, no finite‐element modeler has been utilized. Work is presented on approximation strategies in the development of the analytical model of the sample case to improve the efficiency of the animation.
