Simulation and experimental investigation of active lightweight compliant mechanisms with integrated piezoceramic actuators

Abstract

Compliant mechanisms with integrated actuators can enable new function-integrative structures through the elastic deformation of elements without the use of classical links and joints. For such designs, the mechanical behaviour of the mechanism has to be well known, because external loads, the utilised materials and the geometry of the structural parts influence the deformation performance significantly. In order to speed up the development process of such mechanisms, a tool for the dynamic analysis of compliant movements is necessary before any further FEM simulation and manufacturing. Therefore, the paper presents a simulating procedure for active compliant mechanisms obtained through the integration of piezoceramic actuators into fibrereinforced composite structures using a double layer model. A new mechanism was designed, simulated, constructed and tested. The comparison between simulation and experimental results confirm the effectiveness of the presented procedure in regard to the design phase of new active compliant structures.

Smart materials in architecture for actuator and sensor applications: A review

“…In different investigations it was shown, that smart aggregates can be used to monitor reinforced concrete (Song et al, 2007), circular reinforced concrete columns (Gu et al, 2010), reinforced concrete shear walls (Yan et al, 2009), concrete frame structures (Laskar et al, 2009) as well as bridges (An et al, 2014). Modler et al (2016) investigated compliant mechanisms based on integrated piezoceramic actuators for function-integrative structures. In this work, shape change is obtained by elastic deformation of the material instead of movement of joints.…”

Error motion analysis and design of a synthetic probe of thread functional diameter based on the compliant mechanism

“…The compliant mechanism, which is widely used in pre cision engineering and robotics, is an important branch in the modern mechanisms field [22][23][24]. The compliant mechanismbased design was applied to the thread detection, and a threeDOF movement of the measuring tip was realized.…”

Surface Softness Tuning with Arch‐Forming Active Hydrogel Elements

“…To allow the reversible arch-forming of the active elements, active materials can be used. [12][13][14][15] Classes of active/smart/ intelligent materials comprise, for example, hydrogels, [16][17][18] piezoceramics, [19][20][21][22][23][24][25][26][27][28][29] conductive/ conducting polymers, [30][31][32][33][34][35] dielectric elastomer actuators, [2,[36][37][38][39] ionomeric polymer-metal composites (IPMC), [40][41][42][43][44][45] and shape-memory alloys. [46][47][48][49] These materials all have in common that they react to an externally applied activation stimulus.…”
