Abstract: 3RPS/(H) Metamorphic parallel mechanism based on conventional mechanisms is proposed in this study. In contrast to the 3RPS mechanism, the 3RPS/(H) mechanism comprises a novel intermediate metamorphic limb. The different ...

Abstract: Although slump testing has been used extensively to assess the workability of conditioned soil in shield-driven tunnelling, this traditional evaluation method still requires many subjective descriptions. This study developed ...

Abstract: During metal milling, top burrs will inevitably appear on the edge of the workpiece, which seriously reduces the edge quality and assembly accuracy of the workpiece, thereby reducing the service performance of the product. ...
