Unwanted distortion can increase the current in power systems which results in higher temperatures in neutral conductors and distribution transformers. Higher frequency harmonics cause additional core loss in motors which results in excessive heating of the motor core. These エア 物流
How do I solve this convergence problem in Abaqus?
WebApr 13, 2024 · It is worth noting that various techniques which alleviate the convergence difficulties caused by the excessive distortion of low-density elements, play a vital role in the topology optimization of continuum structure with geometric nonlinearity, e.g., see Buhl et al. ... By adopting the total Lagrangian formulation, for minimum end compliance ... WebApr 14, 2024 · An alternative approach for solving the noise issue determined by the backplate is isolating it from the membrane and performing the transduction in vacuum instead of removing it; the separation is made possible by a mechanical hinge, which is able to transmit a mechanical motion between two atmospheres [ 73, 74 ].
