【摘要】：陶粒增强加气砌块是一种新型墙体自保温材料,有着广阔的应用市场。但是目前国内陶粒砌块生产设备的效率较低,不能满足建筑业的需求。陶粒砌块分料机是陶粒砌块生产线重要的组成部分。分料机的设计与研究对提高陶粒砌块生产线的效率和自动化程度有着重要的意义。本文根据对陶粒砌块生产工艺的深入研究,设计开发了陶粒砌块分料机,对其进行了结构设计和建模,完成了虚拟样机装配。并在此基础上,对其进行了运动学仿真和动静态特性的分析。主要的内容如下： 1、根据陶粒砌块的生产工艺,分析了陶粒砌块分料机在生产线中的功能要求,对其进行了功能原理方案和结构方案的设计,并完成样机的三维建模。 2、在虚拟样机的基础上,利用ADAMS软件,对分料机从物料翻转、搬运到卸放的全过程进行了运动仿真,得到各个主要部件的相对位移、速度、加速度及约束力等,检验了分料机运动规律的准确性,并为原动件的选择和静力学的分析提供了理论依据。 3、根据分料机各主要部件的受力状况,通过有限元法对其进行了静力学分析,得到分料机各部件的应力及变形状况,并根据部件各自的特点进行了结构的改进,提高了其性能。 4、在静力分析的基础上,结合有限元分析法和模态理论对分料机的关键部件进行了动态特性分析,得到了其前几阶固有频率和振型,并对各部分进行了结构改进,提高了其固有频率从而获得更好的动态性能。
[Abstract]:Ceramsite reinforced aerated block is a new self-insulating material for wall, which has a wide application market. However, the domestic ceramic block production equipment efficiency is low, can not meet the needs of the construction industry. Ceramic block separator is an important part of ceramic block production line. The design and research of the separator is of great significance to improve the efficiency and automation of the ceramic block production line. In this paper, based on the deep research on the production technology of ceramsite block, a ceramic block separator is designed and developed, and its structure design and modeling are carried out, and the virtual prototype assembly is completed. On this basis, the kinematics simulation and dynamic and static characteristics are analyzed. The main elements are as follows: 1. According to the production technology of ceramsite block, the functional requirements of ceramic block separator in production line are analyzed, the functional principle scheme and structure scheme are designed, and the 3D modeling of the prototype is completed. 2. On the basis of virtual prototyping, using ADAMS software, the whole process of material turnover, moving and unloading is simulated, and the relative displacement, velocity, acceleration and binding force of each main component are obtained. The accuracy of the movement law of the separator is tested, and the theoretical basis is provided for the selection of the original moving parts and the analysis of statics. 3. According to the stress condition of the main parts of the separator, the static analysis is carried out by finite element method, and the stress and deformation of each part of the separator are obtained, and the structure is improved according to the characteristics of each part, and its performance is improved. 4. On the basis of static analysis, the dynamic characteristics of the key parts of the separator are analyzed by means of finite element analysis and modal theory, the first natural frequencies and modes are obtained, and the structure of each part is improved. The inherent frequency is improved to obtain better dynamic performance.
