【摘要】：可升降泳池是一種帶有活動臺面并能夠?qū)崿F(xiàn)臺面在一定的深度范圍內(nèi)位置可調(diào)的游泳池。泳池自動升降系統(tǒng)是可升降泳池的核心機構(gòu)。在國外,泳池升降系統(tǒng)技術(shù)研究已比較成熟并廣泛用于各類型游泳池中,而國內(nèi)對泳池升降系統(tǒng)的研究和應(yīng)用卻很少。鑒于此,本文開發(fā)了一套適用于中大型游泳池的泳池自動升降系統(tǒng),并對其運動、力學(xué)性能及系統(tǒng)控制進(jìn)行了詳盡研究。具體研究內(nèi)容如下:(1)設(shè)計了一種水平絲杠傳動剪叉支撐的泳池升降系統(tǒng)驅(qū)動機構(gòu),通過對其機構(gòu)學(xué)和力學(xué)關(guān)系的研究對系統(tǒng)關(guān)鍵機構(gòu)參數(shù)進(jìn)行了分析優(yōu)化,得到了最佳整體機構(gòu)設(shè)計方案;并對其關(guān)鍵傳動零部件進(jìn)行了結(jié)構(gòu)設(shè)計和參數(shù)校核。(2)基于虛位移原理對泳池自動升降系統(tǒng)進(jìn)行了運動學(xué)分析,得到了系統(tǒng)運動規(guī)律;以剛體動力學(xué)相關(guān)理論為基礎(chǔ),研究了不同工況下泳池自動升降系統(tǒng)的運動學(xué)、動力學(xué)特性。研究表明,系統(tǒng)內(nèi)部各支撐桿和絲杠螺旋副受力存在差異但整體平衡,臺面勻速升降工況下,泳池自動升降系統(tǒng)運行更加平穩(wěn)。最后,對泳池注滿水工況下,泳池自動升降系統(tǒng)的運行狀況進(jìn)行了研究。研究結(jié)果表明,池水會對系統(tǒng)臺面升降產(chǎn)生較大影響。(3)利用有限元分析方法重點對支撐桿進(jìn)行了強度分析、屈曲分析和瞬態(tài)動力學(xué)分析,得到支撐桿靜載和動載工況下的力學(xué)性能;對傳動絲杠進(jìn)行了強度分析和模態(tài)分析,得到傳動絲杠強度、固有頻率及振型。結(jié)果表明,所設(shè)計支撐桿和傳動絲杠能夠完全滿足預(yù)設(shè)系統(tǒng)承載要求,并為系統(tǒng)運行和承載標(biāo)準(zhǔn)制定以及后續(xù)傳動機構(gòu)改進(jìn)提供理論依據(jù)。(4)設(shè)計了泳池自動升降系統(tǒng)運動控制系統(tǒng)總體方案,重點對速度控制回路進(jìn)行了研究分析。建立了變頻器和異步電機控制系統(tǒng)數(shù)學(xué)模型,并運用ADAMS和Simulink軟件對泳池自動升降系統(tǒng)運動控制進(jìn)行了聯(lián)合仿真,應(yīng)用PID控制器建立了控制系統(tǒng)仿真模型。仿真結(jié)果表明,采用PID控制算法的速度控制回路,經(jīng)過PID參數(shù)整定能夠較好地實現(xiàn)泳池自動升降系統(tǒng)臺面的勻速升降。
[Abstract]:The adjustable swimming pool is a swimming pool with movable table surface and can be adjusted within a certain depth range. The swimming pool automatic lifting system is the core mechanism of the swimming pool. In foreign countries, the technical research of swimming pool lift system has been mature and widely used in various types of swimming pool, but the domestic research and application of pool lift system is very few. In view of this, a swimming pool automatic lifting system suitable for medium and large swimming pool is developed, and its motion, mechanical properties and system control are studied in detail. The specific research contents are as follows: (1) A kind of driving mechanism of horizontal lead screw drive shear fork supporting swimming pool lifting system is designed, and the key mechanism parameters of the system are analyzed and optimized by studying the relationship between mechanism and mechanics. The optimal overall mechanism design scheme is obtained, and the structural design and parameter checking of the key transmission parts are carried out. (2) based on the virtual displacement principle, the kinematics analysis of the automatic lifting and lifting system of the swimming pool is carried out, and the system motion rule is obtained. Based on the theory of rigid body dynamics, the kinematics and dynamics characteristics of swimming pool automatic lifting system under different working conditions are studied. The study shows that there are differences in the forces between the supporting rods and the screw pairs of the screw in the system, but the overall balance exists, and the automatic lifting system of the swimming pool runs more smoothly under the condition of constant lift and lift of the table surface. Finally, the operation condition of the pool automatic lifting system under the condition of full water injection is studied. The results show that the pool water will have a great impact on the rise and fall of the system table. (3) the strength analysis, buckling analysis and transient dynamic analysis of the support rod are carried out by using the finite element analysis method. The strength analysis and modal analysis of the drive lead screw are carried out, and the strength, natural frequency and vibration mode of the drive lead screw are obtained. The results show that the designed support rod and drive lead screw can fully meet the loading requirements of the preset system. It also provides the theoretical basis for the system operation and bearing standard formulation and subsequent transmission mechanism improvement. (4) the overall scheme of the motion control system of the automatic lifting and lifting system of swimming pool is designed and the speed control loop is studied and analyzed emphatically. The mathematical model of inverter and asynchronous motor control system is established, and the motion control model of pool automatic lifting system is simulated by Adams and Simulink software. The simulation model of control system is established by using pid controller. The simulation results show that the speed control loop based on pid control algorithm can achieve the uniform speed rise and fall of the table surface of the automatic lifting system of the swimming pool after pid parameter tuning.
