Load-Carrying Capacity Analysis on Derrick of Offshore Module Drilling Rig

Load Carrying Capacity of Simply Supported Variable Thickness Circular Plates

The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...

Optimal Trajectory of Flexible Manipulator with Maximum Load Carrying Capacity

In this paper, a new formulation along with numerical solution for the problem of finding a point-to-point trajectory with maximum load carrying capacities for flexible manipulators is proposed. For rigid manipulators, the major limiting factor in determining the Dynamic Load Carrying Capacity (DLCC) is the joint actuator capacity. The flexibility exhibited by light weight robots or by robots o...

Enhanced load-carrying capacity of hairy surfaces floating on water.

Water repellency of hairy surfaces depends on the geometric arrangement of these hairs and enables different applications in both nature and engineering. We investigate the mechanism and optimization of a hairy surface floating on water to obtain its maximum load-carrying capacity by the free energy and force analyses. It is demonstrated that there is an optimum cylinder spacing, as a result of...

Calculation of Load Carrying Capacity on a Redundant Manipulator

This paper presents a computational technique for determining the maximum allowable load of wheeled mobile manipulators for a desired trajectory. Full load motion of mobile manipulators while carrying a load is an important consideration in their application and motion planning. The number of factors limits the maximum allowable loads, which can be achieved by a mobile manipulator during a give...
