Dynamic mechanical analysis with portable NMR
Journal of Magnetic Resonance, 2022Dynamic mechanical analysis (DMA) is an umbrella term for a variety of rheological experiments in which the response of a sample subjected to an oscillatory force is measured to characterize its dynamic properties. In this work, we present a method for DMA that employs a small unilateral three magnet array with an extended constant gradient to measure ...

Local dynamic mechanical analysis
Micron, 2009While new materials with tailored properties appear every day, the need of appropriate characterization tools is still an important concern. Analyses of thin films on thick substrate are often highly influenced by the substrate properties. A dynamical nanoindentation system has been designed and built through the integration of a nanoindenter head ...

Dynamic Analysis of a Calibration Mechanism
Applied Mechanics and Materials, 2010In order to verify the reliability of a calibration mechanism including a motion component used in the satellite, the dynamic analysis for this mechanism is conducted with modal coordinate reduction method. Firstly, FEM software ABAQUS is employed to calculate the eigenfrequency and mode shapes of this mechanism. Then, the transfer function at some key

DYNAMIC ANALYSIS OF MECHANICAL PART OF A LOCOMOTIVE
Vehicle System Dynamics, 1985SUMMARY Individual components of locomotive spring suspension and damping, including its geometrical disposition, influence not only its riding qualities but its strength as well, and thus also the life expectation of the most exposed parts. The fact, that the mechanical part of the locomotive is considerably loaded when riding along the track of ...

Virtual Dynamic Mechanical Analysis
2021Dynamic mechanical analysis (DMA) provides insight into polymer viscoelastic behavior and its dependence on temperature. In that DMA is applied to a bulk sample, however, inferences about the connection among bulk and molecular behavior are generally speculative.

Dynamic Analysis of Compliant Mechanisms
Volume 5: 27th Biennial Mechanisms and Robotics Conference, 2002A systematic method for dynamic analysis of compliant mechanisms is presented including basic formulations for natural frequencies, modes, dynamic response, and frequency characteristics. Methods for design sensitivity analysis are developed to investigate the effect of various design parameters on the dynamic performance of compliant mechanisms.

Dynamics Analysis of a Controllable Mechanism
Volume 7: 29th Mechanisms and Robotics Conference, Parts A and B, 2005Hybrid mechanism is a kind of controllable mechanism. It may be composed of one or multiple coupled kinematic loops forming a mechanism network, and is highly nonlinear devices. The bond graph approach provides a compact and versatile representation for kinematics and dynamics of hybrid mechanism, and is more suitable for automatic derivation and ...
