Abstract Parallel mechanisms have the advantage of high rigidity, large payload capability, and so on, but positioning accuracy is affected by elastic deflection arising from external load gravity. An approach to improving compensating presented with a 3- R RS parallel mechanism as research object. The implemented introducing springs on moving platform limbs. Taking load, spring force, gravity,...

Grinding can introduce surface and subsurface damage into ceramics, which may reduce the load-bearing area, and thus the residual strength of a ground component. In this study, the principle of continuum damage mechanics (CDM) is applied to predicting grinding damage for ceramics. A nonlinear thermodynamic constitutive model is established to describe the response of ceramics to complex grindin...

The response of rails to moving loads is of interest in the area of high-speed railway transport. For determination of critical velocity of the train a theoretical concept that is based on the assumption that the track structure acts as a continuously supported beam (the rail) resting on a uniform layer of springs is traditionally used. In this contribution dynamic equilibrium of the soil in th...

The present investigation is concerned with the deformation of thermoporoelastic half space with incompressible fluid as a result of inclined load of arbitrary orientation. The inclined load is assumed to be linear combination of normal load and tangential load. The Laplace and Fourier transform technique are used to solve the problem. The concentrated force, uniformly distributed force and a m...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

This paper focuses on load management in looselycoupled federated distributed systems. We present a distributed mechanism for moving load between autonomous participants using bilateral contracts that are negotiated offline and that set bounded prices for moving load. We show that our mechanism has good incentive properties, efficiently redistributes excess load, and has a low overhead in pract...
