Purpose

This paper aims to propose a study on the static behavior of prismatic tensegrity structures and an innovative form for determining the effect of mechanical properties and geometric parameters on the minimal mass design of these structures.

Design/methodology/approach

The minimal mass design in this paper considers a stable class-two tensegrity tower built through stable models. Using the proposed structures, comprehensive parametric studies are performed to examine the mass (in which the masses of joints are ignored), the mass ratio between a class-two tensegrity tower and a single element, both having the same diameter and length and afterward determine a reliable mass saving structure under various circumstances.

Findings

The simulations show that the mass ratio versus the number of units is a nonlinear regressive curve and predicts that the proposed model outperforms the standard model when the variation parameter considered is a vertical force. The difference in mass between these structures is visible when the gap gradually decreases while the number of units increases. On the geometrical aspect, the gap between the masses is not significant.

Originality/value

This paper helps to understand the influences of geometric parameters and the mechanical properties on the design of cylinder tensegrity structures dealing with a compressive force.

受压缩力的棱柱张拉整体圆柱体最小质量设计的基本参数

目的

本文旨在提出一项关于棱柱张拉整体结构静态行为的研究，以及一种确定力学性能和几何参数对这些结构最小质量设计影响的创新形式。

设计/方法/方法

本文中的最小质量设计考虑了通过稳定模型构建的稳定二级张拉整体塔。使用所提出的结构，进行全面的参数研究以检查质量（其中节点的质量被忽略），二级张拉整体塔与具有相同直径和长度的单个元素之间的质量比，然后确定在各种情况下的可靠的质量节省结构。

发现

模拟表明，质量比与单元数是一条非线性回归曲线，并预测当考虑的变化参数是垂直力时，所提出的模型优于标准模型。当间隙逐渐减小而单元数量增加时，这些结构之间的质量差异是可见的。在几何方面，质量之间的差距并不显着。
