in this paper, according to high load capacity and rather large workspace characteristics of cable driven robots (cdrs), maximum dynamic load carrying capacity (dlcc) between two given end points in the workspace along with optimal trajectory is obtained. in order to find dlcc of cdrs, joint actuator torque and workspace of the robot constraints concerning to non-negative tension in cables are ...

in shallow foundations, the third bearing capacity factor, n, has been found to show a decreasing tendency with increasing the foundation size. it is supported by experimental observations and related mainly to stress level dependent nature of the soil. on the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. in thi...

in this paper a performance analysis is presented for a cable-suspended parallel manipulator. experimental results from some first tests are presented and discussed to validate the theoretical calculation of load carrying capacity. the load-carrying capacity during a given trajectory is obtained. this computational technique is tested on a typical planar cable suspended manipulator. the experim...

this paper focuses on the effects of closed- control on the calculation of the dynamic load carrying capacity (dlcc) for mobile-base flexible-link manipulators. in previously proposed methods in the literature of dlcc calculation in flexible robots, an open-loop control scheme is assumed, whereas in reality, robot control is achieved via closed loop approaches which could render the calculated ...

background : experts and staff of rehabilitation centers often do their activities without following the appropriate ergonomic principles and the correct methods of manual load handling. therefore, gradually and with the repetition of these activities they place themselves at risk of musculoskeletal disorders. the aim of this research is the assessment of lifting capacity by the niosh equation ...

cfrp composites have unique application qualities such as high resistance and durability to environmental conditions, having relatively low weight and easy to install in strengthening concrete structure elements. the brackets should be strengthen sufficiently if they are not calculated and implemented well. application of the cfrp is one of the methods for such purposes. the study involves usin...

In this paper, load-carrying capacity in steel shear wall (SSW) was estimated using artificial neural networks (ANNs). The SSW parameters including load-carrying capacity (as ANN’s target), plate thickness, thickness of stiffener, diagonal stiffener distance, horizontal stiffener distance and gravity load (as ANN’s inputs) are used in this paper to train the ANNs. 144 samples data of each of th...

The purpose of this study is to investigate bending moment and the axial load capacity of a pressurized pipe suffering from a through-wall circumferential crack repaired by a composite sleeve. The three-dimensional finite element method (FEM) was adopted to compute the results, and the failure assessment diagram (FAD) was employed to investigate the failure behavior of the repaired pipe. The fi...
