The load capacity of hydrostatic turntables is predominantly governed by the design of oil pads. Optimizing oil pad parameters can substantially enhance turntable performance while reducing power consumption. This study introduces a fuzzy particle swarm optimization (FPSO) algorithm that incorporates compression factors into the particle swarm optimization (PSO) framework to optimize the parameters of oil pads. Reduce its power consumption by about 40 %, while the error between experimental and theoretical values is only 8 %. Compared with traditional PSO algorithms, FPSO converges more reliably in multiparametric environments.

Abstract

Nosilnost hidrostatičnih vrtljivih miz je v veliki meri odvisna od zasnove oljnih blazinic. Optimizacija parametrov oljnih blazinic lahko bistveno izboljša zmogljivost vrtljive mize ter hkrati zmanjša porabo energije. V tej študiji je predstavljen algoritem mehke optimizacije z rojem delcev (FPSO), ki v osnovno optimizacijo z rojem delcev (PSO) vpeljuje faktorje stisljivosti za optimizacijo parametrov oljnih blazinic. Rezultati optimizacije kažejo, da je rabo energije je mogoče zmanjšati za približno 40 %. Rezultati so bili potrjeni tudi eksperimentalno, pri čemer je razlika med eksperimentalnimi in teoretičnimi vrednostmi le 8 %. V primerjavi s tradicionalnimi PSO-algoritmi, FPSO kaže zanesljivejšo konvergenco pri večparametričnih problemih.
