212. "DYN2#1 - Non-Linear data-driven model for a solar tracker aeroelastic simulation"

Castellani Francesco

12/07/2023 10:40

The solar tracker industry has evolved dramatically in recent years with huge PV-farm demanding for challenging structural design. In such framework it is essential to consider aeroelastic wind loads due to flow unsteadiness and vortex shedding. Dynamic loads estimation is therefore not easy: this is due to the fact that, being the tracking systems equipped with a torsional flexible...

213. "DYN2#2 - Phase transitions in a resonating free-piston engine generator"

Dunne Julian

Free-piston engine generators (FPEGs) offer significant advantages over conventional combustion generators, in particular, higher efficiencies, compactness, and lighter weight. These attributes give higher gravimetric and volumetric energy densities, compared to alternatives. Moreover, an FPEG allows unlimited scalability to high power, and also, electrically controlled variable compression...

214. "DYN2#3 - Rubber part characterisation for rotordynamics analysis."

Tezenas Du Montcel Florian

Abstract. This paper presents a method to determine stiffness dynamic characteristics of rubber parts which are used for vibration isolation. The study was motivated by the need of such characteristics to model vibroflot's dynamic behaviour. Vibroflots are used by ground improvement companies to deeply densify sandy soils by vibrations in order to make stable future infrastructures. A...

215. "DYN2#4 - Determining Loads for Down-scaled Testing of Wind Turbine Pitch Bearings using an Augmented Kalman Filter and Reference Measurements"

Dwek Nathan

This article proposes an approach to determine the loads to apply during down-scaled testing of wind turbine pitch bearings. These bearings present unique challenges and failure modes due to their large size, their limited range of motion, and their loads. Because of these particularities, learnings from more common bearing applications cannot be relied upon. On the other hand, accelerated...

216. "DYN2#5 - Identification of vibration damping in 3D-printed lattice structures"

Tanays Rémy

12/07/2023 12:00

As metallic 3D-printing opens the design space for lightweight structural applications, it also raises challenges in terms of low level vibration damping. Reducing the number of parts is avoiding some classical damping phenomena due to friction mechanisms in mechanical assemblies. In addition, metallic materials do not exhibit intrinsic viscous properties that could significantly contribute to...

217. "DYN2#6 - Stochastic Digital Twin of a Composite Plate for Predicting Lamb Wave Propagation"

Teloli Rafael

12/07/2023 12:20

This work presents a framework for stochastic updating for verifying and validating a finite element (FE)-based model - the Digital-Twin - of a composite plate, considering temperature influence on Lamb wave propagation. It begins with a deterministic updating procedure to find optimal mechanical properties, followed by a stochastic updating procedure to obtain probability density functions...
