Time averaged calculations in pulse electrochemical machining, using a strongly non-linear model

摘要: Simulation of the Pulse Electrochemical Machining (PECM) process can provide information on system design and guidelines for practical use. The pulses that are applied to PECM have be described a time scale orders magnitude smaller than physical scales in system. If full detail has taken into account, accurate calculation variable distribution evolutions become computationally very expensive procedure. In previous work authors, approximate techniques were introduced: hybrid Quasi Steady State Shortcut (QSSSC). other authors model steel NaNO3 was introduced. This contains changing polarization behaviour double layer as function metal ion surface concentration, which brings strong non-linearity this paper technique is introduced integrate non-linear methods. To achieve this, strategy methods extended. For QSSSC, handled using an extra convergence level. calculation, live averaging used take care effects. Performing timesteps during high level calculations no longer dictated by pulse characteristics. Using approach, cheap, yet satisfying results obtained. general powerful any multi-timescale
