Online Identification and Verification of the Elastic Coupling Torsional Stiffness

Shock and Vibration, 2016
To analyze the torsional vibration of a diesel engine shaft, the torsional stiffness of the flexible coupling is a key kinetic parameter. Since the material properties of the elastic element of the coupling might change after a long-time operation due to

Torsional Stiffness Comparison of Different Tube Cross-Sections of a Formula SAE Car Space Frame

MATEC Web of Conferences, 2018
Since torsional loading and the accompanying deformation of the frame and suspension parts can affect the handling and performance of the car, torsional stiffness is generally thought to be a primary determinant of frame performance for a FSAE car ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

An Analysis of Traction Drive Torsional Stiffness [PDF]

Journal of Mechanisms, Transmissions, and Automation in Design, 1985
An analysis of the tangential compliance of elastic bodies in concentrated contact is applied to traction drive elements to determine their torsional stiffness. Both static loading and rotating conditions are considered. The effects of several design variables are shown. The theoretical torsional stiffness of a fixed ratio multiroller traction drive is
