Analysis of three-bars tensegrity structure with additional cable
摘要
Abstract
Tensegrity was a special cable-bar structure composed of discontinuous compression bar member and continuous tension cable,which had the characters of small quality,nice mechanical properties and high material utilization.The stability range of three-bars tensegrity structure was analyzed and expanded by adding an additional cable.The torsional angle ranges of the stable structure before and after adding the additional cable were obtained by analysis of the structure force balance.According to the node coordinate and the connection matrix,the component vector was obtained and the equilibrium matrix of the structure was established.The stable configuration of three-bar tensegrity structure was verified by MATLAB simulation program,and the range was extended from the two single value angles of the basic configuration to the closed interval domain with these two angles as the boundary.关键词
