LOWER BOUND EIGENVALUES OF A TIMOSHENKO-EHRENFEST VIBRATING BEAM USING THE WITTRICK-WILLIAMS ALGORITHM

HUMAN UPPER LIMB MODELLING OF PARKINSONIAN TREMOR THROUGH NEURAL NETWORK AND MULTIBODY SIMULATION

Parkinson's disease is a neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Tremors significantly impact the quality of life for individuals affected by the disease, making it crucial to explore innovative approaches for effectively improving the Activities of Daily Living (ADL). This study focuses on the dynamic modeling of the human upper limb to understand and control Parkinsonian tremors. On the first the study focuses on the develo...

DYNAMIC MODELLING OF A CONTROLLED ORTHOTROPIC PLATE: ANALYTIC AND DATA-DRIVEN APPROACHES IN THE FREQUENCY DOMAIN

This paper is devoted to the mathematical modelling of a vibrating orthotropic plate equipped with a laminated piezosensor, under the influence of a lumped force actuation. We employ the Kirchhoff plate theory to derive the corresponding partial differential equation, assuming free boundary conditions. Analytical solutions for this boundary value problem are explored in the form of series expansions, using products of Krylov functions. Utilizing Galerkin’s method, this mathematical model is t...

Loaded and Unloaded Tooth Contact Analysis of Spiral Bevel Gear in Consideration of Misalignments

Bevel gear pairs are employed extensively in transmission systems, such as vehicle transmissions (rear axle drive), aircraft engines/turbines, and helicopter gears, for transferring power between non-parallel shafts at high speed or torque. The most complex form of bevel gear is the spiral bevel gear (SBG). SBGpairs are commonly used in applications that require high load capacity at higher operating speeds than are typically possible with other types of bevel gears. Spiral bevel gears, when ...
