【摘要】：立體車庫具有容量大、占地少、停車方便等優(yōu)點,特別是機械式立體車庫還能夠自動控制,使其具有自動停車的功能,適合日益擁擠的大都市停車的需求。摩天輪立體車庫是立體車庫設計中的一種新的設計概念,但目前關于摩天輪式立體車庫都是靠汽車自身的重力保持水平,在運行過程中會出現(xiàn)搖擺等不穩(wěn)定的現(xiàn)象,其設計及理論分析還不夠完善。本文提出一種新型的機械式摩天輪立體車庫,能夠有效的解決該問題。本文對該立體車庫進行設計及分析,主要分為三個大的部分,第一部分首先闡述了車庫各個系統(tǒng)的組成部件,各個系統(tǒng)之間的連接方式與約束關系以及詳細說明立體車庫的停取車方式。根據(jù)四桿機構的運動學理論,建立車庫各個系統(tǒng)的運動學關系,并聯(lián)系車庫的停車平臺對車庫做運動學分析。采用SOLIDWORKS繪制出原理模型的各個部件加以組裝,并采用仿真軟件ADAMS對模型運動仿真,從仿真的結果驗證車庫原理的可行性。第二部分主要分析得到單個車庫的尺寸,單個車庫主要由車輪限位裝置與圓筒形車庫組成,因此設計單個車庫尺寸需要結合兩者,并根據(jù)實際情況得出。首先,詳細介紹車輪限位裝置的結構以及該裝置的運行過程。以某品牌的旗下的最大型轎車為基礎,繪制出單個車庫的模型,并采用有限元分析軟件ANSYS WORKBENCH,對單個車庫的形狀以及尺寸進行優(yōu)化,采用參數(shù)優(yōu)化的方式,對各種臨界情況仿真分析,得出支撐平板兩層工字梁的規(guī)格和尺寸,并按照同樣的工況,采用拓撲優(yōu)化對單個車庫形狀進行優(yōu)化,得出在滿足強度條件的前提下,質(zhì)量最小車庫的形狀和尺寸。最后,驗證優(yōu)化后的單個車庫是否滿足強度要求。第三個部分根據(jù)動力學理論基礎,運用拉格朗日方程對車庫模型進行動力學分析。對整個車庫在滿載的情況下進行強度分析,在滿足強度條件的前提下,對車庫主系統(tǒng)進行模塊劃分。在此基礎上計算出車庫的有效轉(zhuǎn)矩參數(shù)方程,根據(jù)此分析車庫的不平衡性。最后,對車庫主系統(tǒng)的驅(qū)動功率以及傳動比進行分析以得到驅(qū)動功率以及驅(qū)動系統(tǒng)的傳動比。
[Abstract]:The three-dimensional garage has the advantages of large capacity, less occupation, convenient parking and so on. Especially, the mechanical three-dimensional garage can also be automatically controlled to make it have the function of automatic parking. The Ferris Wheel Stereo Garage is a new design concept in the design of the Stereo Garage, but at present, the Ferris Wheel Garage is kept level by the gravity of the car itself. The design and theoretical analysis of unstable phenomena such as rocking will occur in the course of operation. This paper presents a new type of mechanical ferris wheel stereo garage. The design and analysis of the three-dimensional garage is mainly divided into three parts. The first part describes the components of each system of the garage. According to the kinematics theory of the four-bar mechanism, the kinematics relationship of each system of the garage is established. With the parking platform of the garage, the kinematics of the garage is analyzed. The components of the model are drawn out by SOLIDWORKS, and the simulation software ADAMS is used to simulate the motion of the model. In the second part, the size of a single garage is obtained. The single garage is mainly composed of wheel limiter and cylindrical garage, so the size of a single garage needs to be combined with the two. First of all, the structure of the wheel limiter and the running process of the device are introduced in detail. Based on the largest sedan of a brand, the model of a single garage is drawn. The shape and size of a single garage are optimized by using the finite element analysis software ANSYS WORKBENCH. by means of parameter optimization, all kinds of critical conditions are simulated and analyzed, and the specifications and dimensions of the supporting plate two-story I-beam are obtained. According to the same working condition, the shape of single garage is optimized by topology optimization, and the shape and size of mass minimum garage are obtained under the condition of satisfying the strength condition. Finally, In the third part, according to the dynamics theory, the Lagrange equation is used to analyze the dynamics of the garage model, and the strength analysis of the whole garage under the condition of full load is carried out. On the premise of satisfying the intensity condition, the main system of the garage is divided into modules. On this basis, the effective torque parameter equation of the garage is calculated, and the imbalance of the garage is analyzed according to the equation. The drive power and drive ratio of the main system are analyzed to get the drive power and the drive ratio of the drive system.
