Achieving high surface quality is vital for improving the reflectivity of aluminum alloy optical components. However, materials often have large-sized grain structures, and stress accumulates at boundaries during ultraprecision machining processes, resulting in raised a decrease quality. In this work, we utilized multiple energy shot peening (SP) technique to refine structure Al-Mg-Si alloy. The results revealed that gradient was formed within depth range 0∼150 μm, accompanied by occurrence...
Buildings and Constructions in civil engineering have led to quite a large production of excavated soil wastes. In order use waste, this paper investigated the physical mechanical properties soil-based unfired clay bricks (ESUCB) with different mix proportions before after dry-wet cycles. A total 108 specimens are separated into nine groups according criterial orthogonal experimental design four factors (i.e., water-to-cement ratio, cement-to-excavated fine recycled concrete...
This paper presents an improved dynamic model for unbalanced high speed motorized spindles. The proposed includes a Hertz contact force which takes into the internal clearance and electromagnetic based on energy of air magnetic field. nonlinear characteristic is analysed by Lyapunov stability theory numerical analysis to study properties spindle system. Finally, operating test carried out DX100A-24000/20-type spindle. good agreement between solutions experimental data indicates that capable...
The physical characteristics of silicon carbide materials, such as brittle texture and high hardness, make it very difficult to form complex structures. Additive manufacturing can realize the direct molding structure mirrors, improve processing efficiency, reduce costs. In this paper, an additive mirror substrate is processed by combined process grinding, lapping, polishing with a small grinding head. After obtaining certain surface shape accuracy, was modified obtain layer thickness 10 μm....
