根据矫直机工作原理以及无缝钢管的特殊工艺,通过弯矩理论和材料力学理论从理论上计算出了六个辊的矫直力解析解。分析了预紧力规律和预紧理论,从而确定了矫直机机架需要施加的预紧力。创新性的完成了矫直机机架的力学模型的实体有限元化。有限元计算结果显示机构符合设计要求。计算结果有助于同类机构的设计。
According to the working principle of the straightening machine and the special process of the seamless steel pipe, the analytic solution of the straightening force of the six rollers is theoretically calculated by the theory of the bending moment and the material mechanics. The rules of pretensioning and pretensioning are analyzed, so the pretensioning force of the straightening machine frame is determined. Innovative completion of the straightening machine mechanical model of the physical finite element. Finite element results show that the mechanism meets the design requirements. The calculation results help the design of similar institutions.
