作为建筑工程机械,混凝土泵车在高空浇筑作业中发挥着关键作用。工程机构的结构部件是否先进,使用起来精准度是否能达到施工要求,而且不容易出现故障,这都要求严格精准的设计和计算来保障。因此,混凝土泵车臂架模型的正确创建对控制算法的研究有至关重要的作用。目前对柔性模型的仿真研究中,都只是创建了模型的柔性文件,却没有进一步验证建立的柔性模型是否能准确反映物体的运动状态。本文在机械系统动力学自动分析中替代刚性臂,构建混凝泵车臂架系统,建立同比例泵车模型,根据传感器的作用,并进行网格划分与编写仿真脚本文件,对泵车工作时常见的起动和制动过程进行仿真研究。通过对柔性体模态阻尼比的设置,使柔性泵车模型仿真出混凝土泵车的工作状态,为进一步的控制算法理论基础探讨做出边际贡献。
As a construction machinery, concrete pump truck plays a key role in high-altitude pouring operation. Whether the structural parts of engineering institutions are advanced, the use of precision can meet the construction requirements, and not prone to failure, which require strict precision design and calculation to protect. Therefore, the correct construction of concrete pump truck boom model plays a crucial role in the research of control algorithm. At present, only the flexible files of the model are created in the simulation of the flexible model. However, it can not be further verified whether the established flexible model can accurately reflect the motion state of the object. In this paper, automatic mechanical system dynamics analysis instead of rigid arm, the construction of concrete pump truck boom system, the establishment of the same pump model, according to the role of sensors and meshing and the preparation of simulation script file, pump work Common starting and braking process simulation study. By setting the modal damping ratio of the flexible body, the flexible pump truck model is simulated to the working state of the concrete pump truck, making a marginal contribution to the theoretical basis of further control algorithms.
