“…In 2007, Soykasap, et al [10], studied the performance of four different tape spring hinges by test apparatus design independently, and got the moment-rotation profiles of the hinges. Later, Mallikarachchi, et al [11,12], studied the quasi-static folding and deploying of the composite tape spring hinges by numerical and experiment methods.…”

Abstract:Tape spring is straight, thin-walled, elastic strip with curved cross-section, which can replace traditional hinges by allowing for folding elastically and unfolded releasing stored energy with fewer component parts. This work is devoted to the properties of the folding and deployment of simple tape spring by numerical simulation and experiment method. Firstly, the folding process of tape spring is experimentally investigated using a specially designed test rig and verified by using nonlinear finite element ABAQUS/Standard solver. Then the moment-rotation relationships for symmetric bending are studied, the effects of subtended angle of section, total tape spring length, thickness and cross section radius on the performance of tape spring are investigated. Furthermore, the optimal model of tape spring structure design is established based on the response surface methodology (RSM) and parameter's effective analysis, which aims at maximum strain energy during the tapespring hinge deployment and subjects to allowable stress of tape spring. And the interior point algorithm is used to solve the optimal model. The optimal results are of great importance to the design of novel deployable structures with high stability, reliability and lightweight.

“…Furthermore, they derived a deployment equation for calculating the deployment performance using the Lagrange equation; finally, they designed a tape spring hinge for the deployment of a single solar panel [2,3]. Soykasap also conducted nonlinear FE analysis of a tape spring hinge using an artificial damping method supported by the commercial solver Abaqus [4]. Walker et al investigated the moment-rotation relationship when a tape spring hinge is folded at an arbitrary angle [5,6].…”

“…Jeong et al described the relationship between the design parameters of a tape spring hinge and the deployed bending stiffness, deployment torque, and maximum folding stress by a response surface using the Box-Behnken experimental design. Furthermore, they used Soykasap's FE model [4] to obtain the moment-rotation curvature; finally, they designed a tape spring hinge for maximizing the deployed bending stiffness on the hinge level [14].…”

“…Finally, more complex and compact three dimensional foldings can be obtained and were studied, first analytically in [10], then experimentally in [11,12]. Tape springs can also be combined to form tape spring hinges [13]. A generic one called MAEVA was developed by the CNES and 01dB-Metravib [14] and was successfully used to deploy solar panels, antennas and masts on the six MYRIADE micro-satellites [15].…”

Importance of structural damping in the dynamic analysis of compliant deployable structures

Compliant mechanisms such as tape springs are often used on satellites to deploy appendices, e.g. solar panels, antennas, telescopes and solar sails. Their main advantage comes from the fact that their motion results from the elastic deformation of structural components and the absence of actuators or external energy sources. The mechanical behaviour of a tape spring is intrinsically complex and nonlinear involving buckling, hysteresis and self-locking phenomena. In the majority of the previous works, dynamic simulations were performed without any physical representation of the structural damping. These simulations could be successfully achieved because of the presence of numerical damping in the transient solver. However, in this case, the dynamic response turns out to be quite sensitive to the amount of numerical dissipation, so that the predictive capabilities of the model are questionable. In this work based on numerical case studies, we show that the dynamic simulation of a tape spring can be made less sensitive to numerical parameters when the structural dissipation is taken into account. I INTRODUCTIONWith the extensive development of small satellites and cubesats dedicated to low-cost missions, the mass reduction of the components is paramount. However, the power reduction due to the miniaturisation of electronic equipment does not follow the same downward slope. Thus, covering only the external surface of the satellite with solar cells might not provide enough power and be too restrictive, hence the necessity for a reliable but cheap and simple means to deploy large solar panels. This, however, brings another major problem that must be solved: the packaging of large structures into the confined space inside the fairing of launch vehicles. In order to address these challenges, deployable structures have been developed and a brief listing of the most common structures can be found in [1]. This paper will focus on those belonging to the compliant mechanisms category and in particular on tape springs.A tape spring is a thin strip curved along its width commonly known as a Carpenter tape and used in the everyday life as tape measures. Nowadays, it finds applications in the space domain for the deployment of appendices such as solar panels, antennas, telescopes and solar sails. Since they belong to the category of compliant mechanisms, they rely only on elastic energy that is stored during the folding and then naturally released when deployed. Indeed, a possible equilibrium state when the tape spring is free of constraints is the straight configuration, which is sought as a deployed configuration for many space applications. This characteristic also brings forward the fact that no source of external energy is required for the deployment and hence the passive and selfactuated behaviours of these devices.Their motion results from the deformation of structural components only and not from the sliding between contact surfaces as in usual hinges or prismatic joints. It implies that tape springs do not requ...
