AbstractTensegrity structures are a special class of lightweight truss structures, where all truss elementsare axially loaded and tensile truss elements are made of strings. This paper presentsthe dynamic analysis of a tensegrity structure by comparing a finite element model with anidentified model obtained from experimental data. Experimental data is obtained by placinga three stage tensegrity structure on a shaker table and measuring frequency responses betweenthe moving support and multiple accelerometers placed on the structure. An identifiedSingle-Input-Multiple-Output (SIMO) linear model is found by a SIMO curve fitting of themeasured frequency responses. To complete the dynamic analysis, the estimated model alongwith the identified resonance modes and damping coefficients are used to compare and finetune a fine element based model.Keywords: tensegrity structure, dynamic analysis, frequency domain identification, finite elementmodels1 IntroductionTruss structures, where all truss members are axially loaded and separated in tensile and compressiveload carrying members, form a basis for the design of tensegrity structures. As such,tensegrity structures differ from regular trusses by purposefully designing all tensile elements tobe strings. The result is a lightweight structure with comparable stiffness properties to regulartruss structures. Tensegrity structures were first introduced as an art form in 1948 by Snelson(1965 年). フラーによって作業 (1962 年) 認識工学値。直接接触に圧縮の要素がないようにテンセグリティ構造を設計することができます。(クラス 1 テンセグリティ)。圧縮の要素間の接続によって達成される柔軟な引張文字列要素。注目されているこれらの柔軟なテンセグリ ティーの構造物の設計静的の構築と構造 (ペッレグリーノと Calladine の機械的安定性に支払われる1985 年) (ペッレグリーノ 1989年) と (追い越し 1992年)。テンセグリティの包括的な静的解析のため1 つはまた言われるスルタン (1999) またはスルタン et al.
