ABSTRACT: An attempt has been made to study and analyze the performance of a magnetic fluid based squeeze film in a rough porous parallel plate slider bearing. The bearing surfaces are considered to be transversely rough. The random roughness of the bearing surfaces is characterized by a stochastic random variable with non-zero mean, variance and skewness. A magnetic fluid is taken as the lubri...

Planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. The problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. Open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

Some explicit analytical expressions of the dynamic shear load-carrying capacity for brittle materials under a quadratic waveform loading are presented on basis incubation time fracture criterion, by which can be determined from quasi-static material parameters, and stress wave conditions (loading amplitude, duration, waveform). The numerical results in good agreement with previous experimental...

This study aimed to investigate the chloride-binding capacity of alkali-activated fly ash (denoted as FSW) and slag (denoted as SSW) samples and their synthesized Cl-bearing phases, which are capable of binding and immobilizing chloride when seawater is used as the mixing water. This study also examined the progressive changes in the pore structures of the FSW and SSW samples over time. The res...

Isotropic ultra-thin shells or membranes, as well cable–membrane structures, cannot resist loads at the initial state and always require a form-finding process to reach steady state. After this stage, they can work in pure membrane quickly experience large deflection behavior, even with small amplitude of load. This paper aims improve load-carrying capacity strength structures via exploiting ad...
