摘要: 为了研究某新型塔式多级旋转混凝土布料机在不同工况下结构的受载情况,并对其结构进行合理优化,采用全工况分析的研究方法,基于ANSYS有限元分析平台编写了布料机全工况分析程序,实现了布料机在全工况下的静力学分析,得到了全工况下布料机的整机位移与应力分布情况,并总结了布料机两级臂架旋转角度对布料机整机应力与位移的影响规律。随后对布料机的危险工况进行分析研究,根据分析结果对布料机结构进行适当优化并对布料机施工控制提出相应改进建议。结果表明,布料机结构经优化后,结构强度和刚度均得到了提高,应力分布更为均匀。

Abstract: In order to study the load conditions of a new kind of multistage rotary concrete spreader in different working conditions and reasonably optimize the structure, the method of full-working condition analysis is employed. Firstly, an analysis program of full-working condition of spreader was compiled through ANSYS, which made it possible to conduct static analysis for the spreader under different working conditions. Through static analysis, the movement distance and stress distribution of spreader under full-working condition were obtained, and the variation law of movement distance and stress with rotary angle of distributing arm was summarized. Moreover, the dangerous working condition of the concrete spreader was analyzed to optimize the structure, and correspondent improvement solution on spreader operation control was proposed. After optimization, the strength and stiffness of the structure was improved and the stress distribution was more homogeneous.
