Winding Modeling and Driving Method of Varying Length Rope Based on ADAMS

It is necessary to study the dynamics and load-bearing characteristics of ropes in order to guarantee the stability and reliability of hoisting equipments. Based on ADAMS, a parametric coupling model of rope winded along cylindrical helix is built by force field. An optimized simulation method, cooperating fixed joints with angle sensors under the control of script, is recommended. Studying on the construction system of deep vertical shaft wall, the bucket is placed at static equilibrium position by preload defined in force field and dynamics behaviors of the center of mass in bucket are researched. The results indicate that the displacement curve is successive and complete, thus it confirms that the driving method is reasonable and feasible. This method could not only guarantee the accuracy and stability but also increase simulation efficiency, providing a new simulation approach for one kind of flexible body such as ropes and cables.
