To improve the stiffness and to realize lightweight of working table direct-drive machine tool, similarity between wing structure is analyzed. The structural characteristics membrane veins are used as design guidelines for bionic ribbed plate table. A new finally obtained. static properties common table, leaf compared with finite element simulation. 3D printer fabricate an equally scaled-down model reliability simulation results verified through load experiments. Deformation morphology...
This study proposes a traveling wave ultrasonic motor with metal/polymer-matrix material compound stator. The stator is composed of metal ring and polymer-matrix teeth. resonance frequency the different structural dimensions was analyzed by finite element method. From results, structure parameters were obtained. effects density elastic modulus tooth on also investigated. A viscoelastic contact model built to explore state between rotor. Considering density, tribological properties, prepared...
Surface texturing is an effective approach to improve the tribological properties of mechanical components. An indentation method presented fabricate dimple textures on bronze specimen surfaces. Graphite was selected as mating balls in ball-on-disc wear tests. The worn surfaces and indented dimples heaped with thin ribbon debris were observed by microscope. morphology evolution employed explain influence textures. experimental results indicate that generation due edge hardening dimple....
The problems of the recast layer, oxide and heat-affected zone (HAZ) in conventional laser machining seriously impact material properties. Coaxial waterjet-assisted scanning (CWALSM) can reduce conduction accumulation heat by high specific capacity water realize nickel-based special alloy with almost no thermal damage. With developed experimental setup, ablation threshold drilling experiments K4002 were carried out. effects various factors on damage thickness studied an orthogonal...
A novel method called tip-viscid electrohydrodynamic jet printing (TVEJ), which produces a viscous needle tip jet, was presented to fabricate 3D composite osteochondral scaffold with controllability of fiber size and space promote cartilage regeneration. The process, by harnessing the combined effects thermal, flow, electric fields, first systematically investigated simulation analysis. influences process parameters on modes resolutions were quantitatively guide fabrication various...
Abstract To improve the tribological characteristics of dimples on surface 45 steel, were filled with MoS 2 and modified by dopamine (MoS @ DA), ball‐disk friction wear tests conducted. Specifically, dimple filling gap, abrasion depth, cross‐sectional area steel measured. The morphology ball exfoliation in bending specimens studied. coefficient DA‐filled specimen was 17.9% lower than ‐filled specimen, gap 70.1% lower, depth 5.8% 17.7% smaller. Moreover, strength DA 3.27 times greater that...
Purpose The study aims to compare tribological properties between laser dimple textured surface and drilled surface, analyze the influence of hardened edges ability trapping wear debris on surfaces. Design/methodology/approach Circular dimples were produced AISI 1,045 specimen surfaces using texturing (LST) (DST) methods. Tribological behaviors LST, DST non-textured specimens studied ball-on-disc tribo-tester. Metallographic structures, worn morphologies observed a three-dimensional digital...
PTFE-filled textured surfaces were impregnated with the dopamine dipping solution to improve their tribological performances. Ball-on-disc wear experiments conducted compare properties of three surfaces: surface, filled surface and modified surface. The worn surfaces, debris, shedding areas PTFE measured, shear strength between block medium carbon steel after impregnation modification was analysed. Experimental results showed that compared had lower friction coefficient values...
