【摘要】：立体车库具有容量大、占地少、停车方便等优点,特别是机械式立体车库还能够自动控制,使其具有自动停车的功能,适合日益拥挤的大都市停车的需求。摩天轮立体车库是立体车库设计中的一种新的设计概念,但目前关于摩天轮式立体车库都是靠汽车自身的重力保持水平,在运行过程中会出现摇摆等不稳定的现象,其设计及理论分析还不够完善。本文提出一种新型的机械式摩天轮立体车库,能够有效的解决该问题。本文对该立体车库进行设计及分析,主要分为三个大的部分,第一部分首先阐述了车库各个系统的组成部件,各个系统之间的连接方式与约束关系以及详细说明立体车库的停取车方式。根据四杆机构的运动学理论,建立车库各个系统的运动学关系,并联系车库的停车平台对车库做运动学分析。采用SOLIDWORKS绘制出原理模型的各个部件加以组装,并采用仿真软件ADAMS对模型运动仿真,从仿真的结果验证车库原理的可行性。第二部分主要分析得到单个车库的尺寸,单个车库主要由车轮限位装置与圆筒形车库组成,因此设计单个车库尺寸需要结合两者,并根据实际情况得出。首先,详细介绍车轮限位装置的结构以及该装置的运行过程。以某品牌的旗下的最大型轿车为基础,绘制出单个车库的模型,并采用有限元分析软件ANSYS WORKBENCH,对单个车库的形状以及尺寸进行优化,采用参数优化的方式,对各种临界情况仿真分析,得出支撑平板两层工字梁的规格和尺寸,并按照同样的工况,采用拓扑优化对单个车库形状进行优化,得出在满足强度条件的前提下,质量最小车库的形状和尺寸。最后,验证优化后的单个车库是否满足强度要求。第三个部分根据动力学理论基础,运用拉格朗日方程对车库模型进行动力学分析。对整个车库在满载的情况下进行强度分析,在满足强度条件的前提下,对车库主系统进行模块划分。在此基础上计算出车库的有效转矩参数方程,根据此分析车库的不平衡性。最后,对车库主系统的驱动功率以及传动比进行分析以得到驱动功率以及驱动系统的传动比。
[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.
