Computational simulation models with different fidelity have been widely used in complex systems design. However, running the high-fidelity (HF) tends to be very time-consuming, while incorporating low-fidelity (LF), inexpensive into design process may result inaccurate alternatives. To make a trade-off between high accuracy and low expense, an active learning variable-fidelity (VF) metamodelling approach aiming integrate information from both LF HF is proposed. In proposed VF approach,...
Accurate monitoring and prediction of tool wear conditions have an important influence on the cutting performance, thereby improving machining precision workpiece reducing production cost. However, traditional methods cannot easily achieve exact supervision in real time because complexity time-varying nature process. A method based Digital Twin (DT), which establish a symmetrical virtual system matching exactly actual system, is presented herein to realize high predicting wear. Firstly,...
The solidification cracking behavior in laser welds of steel/copper dissimilar metals was systematically investigated. T2 copper and SUS304 stainless steel were used the study. results showed that occurrence synergistic effect ε phase liquation, inclusions composition segregation. During welding process, liquation grain boundaries substantially reduced cohesion between adjacent grains, as well resistance for intergranular crack propagation. segregation inside grains could induce lattice...
The external static magnetic field has significant influence on the microstructure and mechanical properties of weld bead during 316L stainless steel laser welding. quality a joint welding supported by (LWSMF) is significantly influenced processing parameters. Hence, how to choose appropriate parameters for good-quality LWSMF important. This paper develops hybrid methodology combining radial basis function neural network (RBFNN) genetic algorithm (GA) address this issue. Firstly, appearance,...
As a representative type of superalloy, Inconel 718 is widely employed in aerospace, marine and nuclear industries. The significant work hardening behavior can improve the service performance components; nevertheless, it cause extreme difficulty machining. This paper aims to investigate influence chamfered edge parameters on orthogonal cutting based novel hybrid method, which integrates Coupled Eulerian-Lagrangian (CEL) method grain-size-based functions considering grain size microhardness....
A 3D non-axisymmetric hybrid plasma model in fiber laser-arc welding is developed, which the laser induced considered as ejecting vapor from keyhole with specific radius, temperature and velocity. The effects of velocity, distance between arc are simulated discussed. From simulation results, height higher lower temperature, bigger velocity larger arc. decreases compared under all parameters, very benefical to reduce distortion resulted heat input. current density has a complex dependence on...
Purpose Engineering system design and optimization problems are usually multi-objective constrained have uncertainties in the inputs. These might significantly degrade overall performance of engineering systems change feasibility obtained solutions. This paper aims to propose a robust approach based on Kriging metamodel (K-MORO) obtain Pareto set under interval uncertainty. Design/methodology/approach In K-MORO, nested structure is reduced into single loop ease computational burden....
Introduction: Acoustic metasurfaces for underwater wave manipulation have great potential use, but the strong solid-fluid interaction caused by impedance closeness between structure and water brings design difficulty, especially in low-frequency range. Methods: Here a locally resonant metasurface transmissive acoustic waves is proposed using finite element method which each unit consists of one channel three subunits. Each subunit has plate two rubber spacers to form resonator. By changing...
