... the system’s effectiveness. To investigate a possible improvement to modern systems, an artificial neural network-based controller, trained by potential flow simulations, was used to prescribe the optimum future actuation of a ride control system. By prescribing the optimum future actuation in anticipation...

... of fixturing. Numerical simulations using finite element analysis (FEA) have long been used to analyze welding-induced structural distortion. For large assemblies, transient thermal elastic-plastic analysis (TEPA) can take days or weeks to run, and optimization of welding sequence is not feasible. Simplified...

... Segmented models are useful in estimating wave induced loads, particularly for new designs where experience in design loads estimate has not matured yet. Combined with numerical simulation, both methods complement each other and can provide a relatively good estimate of design hydrodynamic loads...

... The effect of oscillating harmonic surge motions on a Wigley hull in deep and shallow water was investigated numerically using unsteady Reynolds-Averaged Navier Stokes (URANSE) CFD simulations in a three-dimensional computational domain. The frequency and amplitude of the surge motions were...

... Reynolds Averaged Navier-Stokes (RANS) equations. The k-ω model was used for the turbulence closure and the massive separation flow behind the box-shaped-vehicle. The rotation of the impeller was simulated by a moving reference frame method and the running attitude was predicted by a dynamic body fluid...
