Abstract Heat dissipation performance is critical to the design of high-end equipment, such as integrated chips and high-precision machine tools. Owing advantages artificial intelligence in solving complex tasks involving a large number variables, researchers have exploited deep learning expedite optimization material properties, heat solid isotropic materials with penalization (SIMP). However, because approach limited by discrete datasets labeled training forms, ensuring continuous...
On-Load Tap-Changer (OLTC) is the only core equipment in ultra-high voltage (UHV) converter transformer that moves frequently, and flexible connection structure (FCS) moveable actuating part of vacuum interrupter drive mechanism OLTC. Minimizing transient stress during movement FCS essential for prolonging its fatigue life, thus pursued by optimizing shape sheet this paper. Peak defined as optimization objective, eight geometrical parameters controlling are variables. A progressive...
Contact stress distribution is sensitive to the interface shape and material stiffness. A combination of stiffness investigated obtain a uniform contact distribution. combined optimization method developed based on evolutionary techniques. The uniformity represented by its variance defined as objective function. gap distance Young's modulus are treated design variables optimization, respectively. fixed sequence, which followed adopted. effectiveness improving verified two cases....
The slip surface has a significant effect on the tribological performances of slider bearing and hydrodynamic journal bearing. Less attention been paid to influence boundary hybrid However, bearings are increasingly used due their intrinsic advantages. effects studied in this work. affecting rule both slip-region location size load-carrying capacity is obtained. Only well-designed could improve bearings. This work provide valuable guide for design high-speed
Abstract Material stiffness, a significant parameter of contact interface, is investigated to improve the uniformity pressure. A interface material stiffness optimization design algorithm developed based on modified solid isotropic with penalization (SIMP) method. The pressure field represented by its variance and defined as objective. node-to-node frictionless elastic theory adopted perform analysis. effectiveness for improving surface verified two cases. Because relationship between...
