The microstructure and mechanical properties have a significant impact on the service performance of materials. This paper compared 2024 aluminum alloy subjected to turning ultrasonic surface rolling process (USRP). It was found that both USRP can cause grain refinement increased microhardness. induced by attributed dislocation proliferation T-phase fragmentation; At same time, quantitative relationship model between microhardness during constructed. results showed precipitation had greatest...
To address the problem that non-conductive materials such as ZrO 2 ceramics are difficult to process using discharge technology. In this paper, a micro-arc machining method with aid of an assistive electrode is proposed. The feasibility was experimentally investigated, and removal mechanism analyzed, well influence laws voltage pulse on time ( T ) material rate (MRR), circularity error (CE) wear (EWR). results show has been successfully realized help titanium powder sandwich-type conductive...
The development and design of new energy-saving system electro-hydraulic power steering (EHPS) has extensive application prospect. EHPS is analyzed by using energy flow method, model based on cost established, relevant compute simulation performed. Tests are carried out the hardware-in-the-loop (HIL) bench. results showed that voltage supply, PWM duty cycle, pump capability, tie rod force, ratio different degree impact cost. This study will provide a theoretical reference practice guidance...
Electrolytic plasma polishing is a new type of surface finishing technology, widely used for high-quality metals and alloys due to its excellent processability. In this paper, the austenitic stainless steel (302) processing material, electrolyte temperature, concentration, voltage, time are as influencing factors. The roughness material evaluation index electrolytic experiments. orthogonal experimental group designed obtain best process parameters through range analysis, influence laws...
Aiming at the demand for fatigue life improvement of 45CrNiMoVA ultra-high strength steel shaft parts, a pre-torsion strengthening process using combination two different angles before and after was proposed based on mechanisms strain hardening, fine grain dislocation strengthening. Through surface integrity measurement, torsional test fracture characterization specimens, main factors affecting were analyzed. The results indicated that size refined plastic deformation increased by two-angle...
The existence of strong uniform attractors for second-order abstract non-autonomous dissipative systems has been extended to the weak and norm-to-weak attractors. Based on dynamic theory systems, this paper is concerned with long-term asymptotic dynamics 3D Benjamin-Bona-Mahony equations less regular external forces. normal, temporally, spatially forces have derived by using spectrum operators an energy equation approach.
Short electric arc milling (SEAM) involves the complex coupling between high-density heat output of arc, high-speed rotation tool electrode, and high-pressure flushing fluid inside tubular electrode. To improve discharge utilization, this study investigates effects mechanical action, mechanical-fluid action on breakage short arcs via experiments. It is found that electrode reduces adsorption working to surface, which can help reduce recast molten metal workpiece surface quality. The two...
This paper is concerned with the tempered pullback dynamics of 3‐D nonautonomous incompressible Navier–Stokes equations nonlinear damping and delay in a bounded domain. Basing on some delicate priori estimates, existence uniqueness weak strong solutions have been proved. Then under appropriate hypotheses external forces, we show minimal family attractors respect to fixed generic universes.
Abstract Groundwater with high concentrations of iron and manganese is harmful to the human body modern industries. Conventional methods treating have disadvantage costs complex control processes. A dielectric barrier discharge (DBD) water treatment system was built remove from groundwater in this paper. Single-factor experiments were used analyze effect power, initial concentrations, gas flow rate, liquid pH, flocculant capture agent process parameters on removal rates. It found that Fe2+...
To solve core problems of slow arc response and unstable combustion, movement characteristics action rules in short electrical milling are studied using a high-speed acquisition system the Phantom camera this article. improve reignition, characteristic parameters discharge determined as gap 0.053 mm time 2180 μs. A experiment with nickel-based superalloy GH4169 is carried out, confirming that continuous stable can easily produce material removal rate 40 g/min tool wear ratio 0.8%. An SU8010...
