基于悬索的阻尼网周边受力分析

Peripheral Force Analysis of Damping Mesh Based on Catenary

将具有弹性拉网机构的阻尼网结构简化成一种在均布气动载荷作用下两端为弹性支承的悬索模型,然后按悬索分析的方法对其变形曲线和周边受力进行了分析,得到了变形曲线和周边张力的表达式,同时也得到了进行弹簧设计的参数表达式。从变形曲线的表达式可以看出这种悬索模型的成型曲线为直线—抛物线—直线,不同于经典的抛物线型或悬链线型。

The paper simplified a damping mesh with elastic regulating tautness mechanism into acatenary model with elastic supports on both ends based on equispaced pneumatic loading.Then,according to suspension-analysis method,the deformation curve and peripheral force of which has been analysed,by which the expressions of deformation curve as well as peripheral force has been obtained,so does the parameter expressions of spring design.In accordance of the expressed formula of deformation curve,it has been shown that the shaped curve of the catenary model is beeline-parabola-beeline,which is different from classical parabola or catenary.
