To reduce the risk of slip, grip force (GF) control includes a safety margin above the force level ordinarily sufficient for the expected load force (LF) dynamics. The current view is that this safety margin is based on the expected LF dynamics, amounting to a static safety factor like that often used in engineering design. More efficient control could be achieved, however, if the motor system ...

A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedd...

For multi-axle distributed drive (MADD) vehicles, the complexity of longitudinal dynamics control system increases with number driven wheels, which presents a huge challenge to multi-motor vehicle more than four wheels. To reduce complexity, this paper proposes coordinated slip algorithm using hierarchical linear quadratic regulator (HLQR) scheme for 12 × MADD vehicle. The 12-wheel driving is d...

This work established a finite element analysis (FEA) model of an inserted tooth-type slip assembly under bear setting load and axial load, calculated the differences between teeth sidetracking packer slip-formed furrow shapes on casing face, analyzed reliability tooth packer. The orthogonal optimization structural parameters was carried out basis effect. Finally, experiment conducted with deve...

this paper deals with three-dimensional evaluation of the slopes on the basis of limit analysis. an upper-bound technique of limit analysis is used in this paper to determine either the bearing capacity of a shallow foundation near a slope or the safety factor of the slope. the theorems of limit analysis (upper and lower bound) provide a powerful tool for solving problems in which limit loads n...

In this study, an experimental program was performed to investigate the cyclic friction-slip behaviour of AS/NZS 3678–350 (G350) steel with different surface finishes. Fifteen bolted connections consisting EN 1090–2 slip factor test assemblies M16 bolts were prepared and tested five commonly used finishes including inorganic zinc silicate (IZS), epoxy primer (EZP), aliphatic acrylic polyurethan...

This study is based on the necessity of sustainable housing in earthquake-prone and wind-prone coastal locations. It focuses determining load-slip behavior, failure mode, ductility low-strength concrete made with brick aggregate containing channel angle shear connectors fixed wide flanged beam. Under monotonic loading, have an average 15.11% 54.81% higher capacity slip than slab. Shear loads fr...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...
