Modeling and Wrench feasible workspace analysis of a spatial cable suspended robots is presented. A six-cable spatial cable robot is used the same as Stewart robots. Due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. Various workspaces are defined and the results of simulation are presented on the basis of various workspaces and app...

This paper addresses the cable tension distributions of a cable-driven parallel robot with non-negligible cable mass for large dimension mechanisms. A well-known model which describes the profile of a cable under the action of its own weight allows us to take the cable sags into account. In addition, an approach to computing the cable tensions is presented, in which there are two major steps to...

Abstract The parameters optimization of a viscous damper is carried out with cable-stayed bridge single cable plane and tower. Based on five four functions energy dissipation structure, the relationship between each function obtained. Finally, spatial distribution surface multi-parameter objective constructed, final result process shows that reasonable can effectively inhibit vibration structur...

Structural diseases are the main threats to safety and daily operation maintenance of cable channels. Through statistical analysis 255 channel structural nationwide, distribution characteristics were studied, seven types structures including cracks, seepage, displacement/deformation, material degradation, siltation, cavity damage revealed. The results show that water leakage, siltation cracks m...

Structural monitoring systems using wireless sensors have the potential to serve as low-cost alternatives to commercially available cable-based monitoring systems. This paper describes a wireless sensing prototype system specifically designed for structural monitoring applications. To validate the performance of the prototype system, a network of up to 20 wireless sensing units is installed on ...

he concept of cable-stayed bridges dates back to the seventeenth century. Due to their aesthetic appearance, efficient utilization of material, and availability of new construction technologies, cable-stayed bridges have gained much popularity in the last few decades. After successful construction of the Sutong Bridge, a number of bridges of this type have been proposed and are under constructi...
