“…MSC/NASTRAN, despite being as widely used, did not posses an inherent modeling approach for piezoelectricity which led to the development of an alternative thermal strain analogy approach and a modified coupled-field finite element approach (Freed and Babuska 1997). The thermal analogy has been shown to be reasonably accurate in terms of static deformation but transient behaviour can require unwieldy models and accurate modeling of any insulating layers is needed to accurately capture dynamic behaviour Côté et al (2004). As a result, it has been investigated further and adopted by many different researchers when modeling the piezoelectricinduced strain (Paradies and Ciresa 2009;Tawfik et al 2011;Bilgen et al 2011;Gustafson 2011;Dwarakanathan et al 2015).…”

“…The relationship of equation (7) concludes that the piezoelectric-driven expansion and contraction can be represented through a thermal load applied to the modeled actuator (Côté et al, 2004). This is quite useful when working with commercial FE software since it allows the piezoelectric actuation to be treated as a thermal expansion property of the material.…”

This article investigates the modeling of macro fiber composite-actuated laminate plates with distributed actuator patches. The investigation details an analytical and finite element modeling, with experimental validation of the bending strain and deflection of an epoxy E-glass fiber composite laminate. An analytical approach is also developed to estimate the plate deflection from the experimental strain measurements. The analytical method uses direct integration of single dimensional plate bending moments obtained by strain-induced shear moments from the macro fiber composite actuators. Finite element analysis software was used with the composite laminate modeled in ANSYS ACP. The results from both analytical and numerical models show good agreement with the experimental results, with strain values agreeing within 20 ppm and the maximum difference in deflection not exceeding 0.1 mm between models. Finally, an application of the analytical model for developing morphing aerofoil designs is demonstrated.

“…Finite element analysis (FEA) is used to compute the displacement and natural frequency of the mechanism without load and further check the stress intensity based on an NX V8.0.0.25 NASTRAN solver [24,25] of Siemens AG in Berlin, Germany, shown in Figure 2. The maximum Von Mises stress 47.63 MPa of the mechanism in Figure 2b is lower than the allowable stress 355 MPa in Table 2.…”

To improve the phase-shifting accuracy, this paper presents a novel integrated framework for design, control and experimental validation of the piezoelectric actuated phase shifter with a trade-off between accuracy and cost. The piezoelectric actuators with built-in sensors are adopted to drive the double parallel four-bar linkage flexure hinge-based mechanisms. Three mechanisms form the tripod structure of the assembled phase shifter. Then, a semi-closed loop controller with inner feedback and outer feedforward loops via the external laser interferometer is developed for accurate positioning of the phase shifter. Finally, experiments related with travel range, step response, linearity and repeatability are carried out. The linearity error is 0.21% and the repeatability error of 10 μm displacement is 3 nm. The results clearly demonstrate the good performance of the developed phase shifter and the feasibility of the proposed integrated framework.

“…Simulation, as an effective alternative of physical testing in terms of both cost and time, allows more design options to be considered in a shorter time (Sellgren 1994(Sellgren , 1995. Thus, various simulation systems, including Ansys, Abaqus, MSC Nastran, etc., have been developed to the needs of developing domain-specific simulations (Côté et al 2004). Therefore, simulation-driven design is becoming the mainstream product design and development process.…”

Simulation-driven design has become an effective methodology for improving the design process in terms of both time and cost. The high-fidelity and efficient visualisation of multidisciplinary simulation results of complex products is crucial for helping designers improve their design. One of the key challenges is to display and view multidisciplinary simulation results that are heterogeneous and tool-specific. In this study, a uniform intermediate model which supports high-fidelity and efficient visualisation of multidisciplinary heterogeneous simulation data is proposed and developed. Firstly, the problem of generating a uniform intermediate mesh model is formalised and represented as an optimisation problem. Then, the genetic algorithm is employed and improved to optimise the uniform intermediate mesh model globally and locally after the direct initial (D-initial) mesh model is refined based on the hybrid mesh size field. Finally, the mapping and interpolation relationships between the uniform intermediate mesh model and the simulation mesh models of different disciplines are established to implement simulation results visualisation in a CAD platform. To improve computational efficiency, two strategies are deliberately employed, namely indexing and parallel computing. Several experiments are conducted to demonstrate the performance of the proposed approach.
