摘要:

讨论了附着式塔式起重机的一层、两层附着两种情况的弹性二阶受力性能.以KZQ2000Z型塔式起重机为研究对象,提出了相应的简化计算模型,对该简化模型进行了二阶效应分析并与有限元软件分析计算的结果进行了比较,计算结果最大相差3.9%.分析结果表明,所提出的简化模型能够反映实际塔式起重机的弹性二阶特征,同时塔式起重机当吊重较大时,二阶受力特点是明显的.

Abstract:

The elastic second-order force performance of the one-layer and two-layer attachment of the attached tower crane is discussed. Taking KZQ2000Z tower crane as the research object, the corresponding simplified calculation model is proposed, and the second-order effect analysis of the simplified model is carried out and compared with the results of the finite element software analysis and calculation, and the maximum difference of the calculation results is 3.9%.The analysis results show that the proposed simplified model can reflect the elastic second-order characteristics of the actual tower crane, and the second-order force characteristics of the tower crane are obvious when the lifting weight is large.
