From the view point of value project,this paper analyses the economic significance of the application of belt conveyors' plane bended device in bended roadway.

In this paper,to aim for requirement of 180°bending device,we describe the design process of a kind of 180~reverse turning bed bending device,which improves bending unit so as to be easier to us

This paper chiefly discusses the problems of bending in mechanics of materials,including the build in differential equation of the deflection curve, the meaning of constant of integration in deflection curve and plane bending of ansymmetrical beam.

Based on the extended homogeneous capacity precision integration method,a novel method was presented for solving plane bending problems of elastic arches with arbitrary profile.

This article embarks on a concrete question,elaborates the essential distinguishes between oblique beding and plane bending.

Several shape memory alloy(SMA) wires are embedded in liquid rubber at room temperature to form planar bending and spacial bending SMA actuators(SMAAs).

The nonlinearity between SMA wire s resistance and temperature makes displacement control of planar bending ESMAAs inaccurate.

To overcome low response speed and low control precision in the existing planar bending ESMAAs, the structures of actuators were improved.
