Bending moment applied to a beam causes out-of-plane deformation to a panel when the panel zone is hollow, and thereby a load bearing by a web cannot be expected in an elastic region.  Since the section modulus of a beam end is limited to the section modulus of only the flange not including the web, the beam end has a low strength.  Therefore, a beam larger in size which bears bending moment on the entire section of the beam must be used and an extra beam depth is required, thus causing an increase in the weight of a steel beam. As the result of various studies, it has been found that various problems could be resolved by increasing the plate thickness of a diaphragm, applying a backing plate to the top surface or the bottom surface of a beam flange, increasing the strength of the material of the beam flange, increasing the thickness of the diaphragm or the backing plate, notching a web, or hot working the bottom surface of the beam to impart prestress thereto.

A display device includes a display panel and a flexible substrate. A first pad and a second pad are arranged on the display panel. The flexible substrate includes a first layer, a first insulating layer, and a second layer on a bending area. A first metal line is arranged in the first layer and connected to the first pad. A second metal line is arranged in the second layer and connected to the second pad. A straightened length of the first metal line is greater than that of the second metal line. The design of a double-layer metal line effectively improves the stress intensity of the metal line in the outer bending area. Therefore, the inner and outer double-line metal line in the bending area is balanced by force, so that the stability of the inner and outer double-line metal line is relatively uniform.

The invention relates to a washing machine for spray-floating washing. The gap between the inner and outer tubs is connected with the inner waterway of the pulsator through the connecting waterway provided with a water pump, and the washing water between the inner and outer tubs is passed through the connecting waterway and the inner waterway of the pulsator by the pulsator. The spray holes arranged on the surface spray into the inner tub, forming an upwardly sprayed water column in the inner tub to wash clothes. Through the above arrangement, an upwelling water column is continuously formed in the inner tub, thereby washing away the clothes and reducing the entanglement of the clothes caused by repeated reversals, thereby avoiding the damage caused by the entanglement of the clothes. At the same time, since the clothes are constantly tumbling during the washing process, the contact area between the clothes and the washing water is increased, and the clothes rub against each other, which effectively improves the washing effect. Also, the present invention is simple in structure and remarkable in effect, and is suitable for popularization and use.

The invention discloses an integral compound bulging process for an automotive driving axle. The process comprises the following steps of: 1) placing an opened axle housing workpiece into an external bulging mold; 2) extending the internal bulging mold into a bulged deformed area of the axle housing workpiece from an inner hole at one end of the axle housing workpiece; 3) closing the external bulging mold; 4) applying equal thrust parallel to the axial direction of the axle housing workpiece to the internal bulging mold by utilizing thrust devices at the two ends of the internal bulging mold respectively, and applying pressure perpendicular to the axial direction of the axle housing workpiece to an upper module and a lower module by utilizing a pressure generation device, wherein the thrust is decomposed into a perpendicular thrust component which acts on the upper and lower module and is perpendicular to the axial direction of the axle housing workpiece and a parallel thrust component parallel to the axial direction of the axle housing workpiece under the action of a link mechanism, bulging force on the axle housing workpiece is the resultant force of the perpendicular thrust component and the pressure, and the axle housing workpiece is bulged and deformed under the action of the bulging force; and 5) performing unloading and demolding.
