【摘要】：傳統(tǒng)動力設(shè)備的隔振,往往僅著眼于設(shè)備本身的振動抑制,而將其連接基礎(chǔ)視為絕對剛性,忽略其振動.考慮"設(shè)備-隔振器-薄板基礎(chǔ)"為復(fù)合隔振體系,設(shè)備通過4點(diǎn)安置在薄板上;并基于機(jī)械四端連接特性,推導(dǎo)了力的傳遞率.隨后,在固支薄板振動分析的基礎(chǔ)上,引入功率流理論,提出了多目標(biāo)優(yōu)化策略:使多點(diǎn)安置的設(shè)備隔振體系輸入薄板的峰值功率流最小;與此同時(shí),使動力設(shè)備盡可能地趨于均勻振動,以降低設(shè)備振動損害.多目標(biāo)粒子群優(yōu)化算法具有參數(shù)設(shè)置少,收斂快,優(yōu)化能力強(qiáng)等優(yōu)點(diǎn),且可基于Pareto支配獲得最優(yōu)解.該研究將設(shè)備隔振、薄板振動、功率流傳遞以及智能多目標(biāo)優(yōu)化技術(shù)結(jié)合,固支薄板振動理論作為切入點(diǎn)為優(yōu)化策略創(chuàng)造了有利條件.多目標(biāo)粒子群優(yōu)化算法的應(yīng)用亦為工程隔振及振動控制提供了新思路.
[Abstract]:The vibration isolation of traditional power equipment is usually focused on the vibration suppression of the equipment itself, but the connection foundation is regarded as absolute rigidity, and the vibration is ignored. Considering that "equipment, vibration isolator-thin plate foundation" is a composite vibration isolation system, the equipment is placed on the thin plate through four points, and the force transfer rate is derived based on the characteristics of the mechanical four-terminal connection. Then, on the basis of the vibration analysis of clamped thin plate, the power flow theory is introduced, and the multi-objective optimization strategy is put forward: the peak power flow of the input plate is minimized by the multi-point isolation system; At the same time, the power equipment tends to the uniform vibration as far as possible, in order to reduce the vibration damage of the equipment. Multi-objective particle swarm optimization algorithm has the advantages of less parameter setting, fast convergence and strong optimization ability, and the optimal solution can be obtained based on Pareto domination. In this study, the vibration isolation of equipment, thin plate vibration, power flow transfer and intelligent multi-objective optimization technology are combined, and the theory of clamped thin plate vibration is used as the starting point to create favorable conditions for the optimization strategy. The application of multi-objective particle swarm optimization provides a new idea for engineering vibration isolation and vibration control.
