【摘要】：在传统的建设施工当中,抹灰工序一般是由人工来操作完成的,但是在当今社会经济快速发展的背景之下,传统的人工抹灰效率已经无法达到市场经济生产效益的需求。为了更好的适应市场经济的竞争,提高总体建设施工的效率以及水平,机械自动化施工获得了快速的成长。同时,随着我国教育水平的不断发展和高等教育的普及,越来越多的工程施工人员都受到了高等教育,施工人员的素质不断提高,因而呈现了“用工难用工贵”的时代难题,一些具有专业技术的抹灰工人变得越来越稀缺并且代价高,使得这道工序的人工成本逐年提高并且难以保证抹灰质量。抹灰机属于新型建筑机械,它由抹灰底架、立杆机构和抹灰机构组成,在当今的建设施工中得到了广泛的应用。本文运用现代机械设计原理以及方法对抹灰机构进行了动力学分析以及结构优化设计。应用机械动力学分析软件ADAMS对抹灰机构进行多刚体动力学分析,利用所建立的虚拟样机模型进行运动学与动力学的仿真分析,得到了抹灰机构中各组件的运动规律,并得出抹灰机构中各组件铰接处以及各组件的受力情况。从模型分析的结果来看,该机构在整个工作循环中运行正常,满足相关设计要求,同时通过以ADAMS为基础的动力学仿真,为下一步的有限元仿真提供了边界条件。然后,利用结构有限元分析软件ANSYS完成摩擦提升机构和抹灰机构的参数化建模,还对支撑杆、摩擦轮与料斗分别建立了有限元模型,对机构进行了有限元分析和优化设计,组装出新型抹灰机样机并进行抹灰实验得到了实际抹灰参数。最终,本文的研究结果对该系列的抹灰机结构动力学设计具有重要的参考价值,并可为现有各种墙体抹灰机的改进和新设计提供指导与帮助。
[Abstract]:In the traditional construction, the plastering process is generally completed by manual operation, but under the background of the rapid development of social economy, the traditional artificial plastering efficiency has been unable to meet the needs of market economy production efficiency. In order to better adapt to the competition of market economy and improve the efficiency and level of overall construction, mechanical automation construction has achieved rapid growth. At the same time, with the continuous development of education level and the popularization of higher education, more and more engineering constructors have received higher education, and the quality of construction personnel has been improved constantly. Some professional plastering workers are becoming more and more scarce and costly, which makes the labor cost of this process increase year by year and it is difficult to ensure the quality of plastering. Plastering machine is a new type of construction machinery, which is made up of plastering base frame, shaft mechanism and plastering mechanism. It has been widely used in construction nowadays. In this paper, the dynamic analysis and structural optimization design of plastering mechanism are carried out by using modern mechanical design principles and methods. The dynamic analysis of plastering mechanism is carried out by using the mechanical dynamics analysis software Adams. The kinematics and dynamics simulation analysis is carried out by using the established virtual prototype model, and the motion rules of each component in the plastering mechanism are obtained. The joints of each component in the plastering mechanism and the stress of each component are obtained. The results of the model analysis show that the mechanism works normally in the whole working cycle and meets the design requirements. At the same time, the dynamic simulation based on Adams provides the boundary conditions for the next finite element simulation. Then, the parametric modeling of friction hoisting mechanism and plastering mechanism is completed by using the structural finite element analysis software ANSYS, and the finite element models of support rod, friction wheel and hopper are established, and the finite element analysis and optimization design of the mechanism are carried out. A new type of plastering machine prototype was assembled and the actual plastering parameters were obtained by plastering experiment. Finally, the results of this paper have important reference value for the structural dynamic design of this series of plastering machines, and can provide guidance and help for the improvement and new design of various existing wall plastering machines.
