Abstract: Disclosed is a gasbag type pavement testing apparatus, comprising a main frame (7), roller wheels (1) and a pneumatic suspension frame system which consists of gasbags (2), ventilated bolts (5), spokes (6), an inflating valve (10), a communicating shaft (11) and rockers (3). The gasbags (2), ventilated bolts (5), spokes (6), inflating valve (10), and communicating shaft (11) constitute an air storing space interconnecting each gasbag, the air storing space is inflated or deflated through the inflating valve (10), and the rockers (3) are hinge-jointed with the spokes (6). The spokes (6), rockers (3) and the communicating shaft (11) constitute a spoke assembly. The roller wheels (1) are driven by the spoke assembly to rotate round the communicating shaft (11), the roller wheels (1) contact the pavement in turn under the joint action of the gasbags (2) and the spoke assembly to simulate the practical situation and hence conduct the rolling test for the pavement.

Abstract: A tack welding method for use with a hybrid laser arc welding process. The method provides a recess on an edge of a first piece. The edge of the first piece is configured to cooperate with a second piece. The method positions the first piece relative to the second piece so as to provide a gap between the first piece and the second piece. Subsequently, the method provides a tack weld within the recess of the first piece. The recess is configured to accommodate placing the tack weld at a root of the gap.

Abstract: Disclosed is a hybrid pole bearingless switched reluctance motor (BLSRM). The BLSRM includes a stator provided with windings, a rotor rotating about an axis when current is conducted to the windings. The rotor includes a plurality of rotor poles extending radially outward, and the stator includes a plurality of stator poles extending radially inward. The windings include suspending windings to generate radial force for the rotor and torque windings to generate torque. The suspending windings are mutually separated from the torque windings. Through the use of the hybrid pole BLSRM, a stator pole generating the radial force can be controlled independently from the stator pole generating the torque by separately arranging the stator pole generating the radial force and the stator pole generating torque based on the analysis of radial force and torque characteristics according to the position of the stator poles.
