Milling force, which can determine factors such as tool wear and chatter, is the most crucial accurate variable for monitoring milling process. However, its application remains limited due to utilization of expensive invasive measurement sensors. Predicting force based on low-cost highly accessible spindle current signals therefore an effective solution. existing method generally inaccurate cannot predict forces in two main directions, namely along feed direction perpendicular direction....
In order to improve the forming quality of extruded thread, finite element analysis and experimental research are combined reduce two keys that affect thread in machining process-extrusion torque extrusion temperature. The effects different processing parameters on temperature obtained by numerical simulation, including bottom hole diameter workpiece, machine tool speed, lubrication medium. For purpose reducing temperature, process for internal further optimized orthogonal design. It is...
The precise prediction of painting man-hours is significant to ensure the efficient scheduling shipyard production and maintain a stable pace, which directly impacts shipbuilding cycles costs. However, traditional forecasting methods suffer from issues such as low efficiency poor accuracy. To solve this problem, paper proposes selective integrated learning model (ISA-SE) based on an improved simulated annealing algorithm predict ship man-hours. Firstly, particle swarm optimization (MPSO)...
Abstract Puffers show good drag reduction performance during migration. It is worth noting that spines which are different from ordinary fish scales densely distributed on the puffer skin. Here, special morphological structure of was observed using microscopy techniques, accurate contour models were established based image processing techniques and curve fitting, then feature sizes obtained. Based results, nonsmooth surface by orthogonal test to simulate flow field. In addition, influence...
A prediction method based on an improved salp swarm algorithm (ISSA) and extreme learning machine (ELM) was proposed to improve line heating forming. First, a three-dimensional transient numerical simulation of forming carried out by applying finite element simulation, the influence machining parameters deformation studied. Second, model for ELM network established data, hull plate predicted training network. Additionally, intelligence optimization, particle optimization (PSO), seagull...
In order to study the biomechanical properties of puffer skin, dorsal and abdominal skin was cut horizontally lengthways. The mechanical parameters quasi static axial tension, relaxation creep were measured under low strain rate. Mooney-Rivlin Zener equations used construct tensile constitutive relations respectively. correlation coefficient fitting results is more than 99%. show that depend on its location direction, showing typical characteristics viscoelasticity, nonlinearity anisotropy...
With the rapid development of aero-engine manufacturing technology, dual-rotor system has been employed in part turbofan engine order to improve working performance aircraft more efficiently. In this study, taking counter-rotation as research object, dynamic model dual rotor-casing coupling is established by aid MATLAB. The frequency curves are good agreement with results references and calculated FEM method, that shows validity feasibility model. local rub-impact established, rubbing...
Purpose In the process of cold rolled strip, there is tight coupling between flatness control and gauge control. The variation roll gap caused by change bending force will lead to rolling force. Furthermore, it can cause a deep impact on accuracy strip exit thickness crown. purpose this paper improve preset value for strip. Design/methodology/approach paper, strategy with considering was proposed first time objective function established basis two-objective optimization Meanwhile,...
Remaining useful life (RUL) prediction in real operating environment (ROE) plays an important role condition-based maintenance. However, the information ROE is limited, especially for some long-life products. In such cases, accelerated degradation test (ADT) effective method to collect data and then are converted normal level of stresses through acceleration factors. different from since there other except stresses, which cannot be accelerated, but still have impact on degradation. To...
