The system is released from rest and the task is to find the magnitude of the linear acceleration of the hoop. Using the equations for torque and force, the acceleration of the rope over the pulley and the acceleration of the sphere can be calculated. However, the first attempt ...
Although Leonardo da Vinci is said to have first depicted the concept on paper, it is Johan Jurgen, a wood-carver from Brunswick, who is claimed to have invented the system in 1530, after da Vinci’s death in 1519. With this system a foot treadle was used to rotate the large wheel ...
Angular effects propagated through system Note: Effects of FN are considered with linear effects and is not considered as part of angular effects. Where Total mass moment of inertia about shaft #2 Mass moment of inertia of pulley #2 Mass moment of inertia for grinding wheel Mass moment of ine...
Advances in the modeling and dynamic simulation of reeving systems using the arbitrary Lagrangian-Eulerian modal method the use of the rotation angles of the sheaves as generalized coordinates together with the rope-to-sheave no-slip assumption as linear constraint equations...

Experimental measurements show that linear system vibration coupling exists between the pulley rotations and the transverse span deflections. Former models that treat the belt as a string and neglect the belt bending stiffness cannot explain this coupling phenomenon. In this paper a new serpentine belt...
It is shown that modeling the cable as a linear spring, although very simple and efficient, is energetically inconsistent and produces spurious terms in the equations of motion if the cable deformation along the segment in contact with the pulley is not considered. In order to overcome this ...
and Zhang, Zu and Hou (2001) further refined this linear model by incorporating belt damping and carried out a complex modal analysis of the hybrid model for the serpentine belt drive system. Parker (2004) developed a spatial discretization of this model ...
Four different control schemes are developed and applied to control the tensioner arm's orientation in the system. These methods are lead-lag compensation control, linear quadratic optimal control, model matching Hinfinity control, and sliding mode control.;Vibration behavior of the belt drive system...
