High-speed deflection and friction force images of sample surface have been obtained successfully.
The deflection signal Id and the friction signal If are fed to two analog input (AI) channels of the high-speed DAQ system S-61155, NAustinl InsTXUSAnts Corp., Austin, TX, USA) for simultaneous high-speed deflection and friction force imaging.
The Campbell diagram, critical speeds, operational deflection shapes, and unbalance response of the rotor are obtained in order to completely investigate the dynamic behavior of the rotating system.
The results of that exploration indicated that even at different design speeds and deflection angles, the CMF estimates for incremental increases in radius lie within the same range, and that the crash reduction rate (CRR) is higher at segments on higher grades compared to the ones on lower grades.
Each wire was deflected 1 mm, at a deflection speed of 1 mm/min (Fig. 3).
Specifically, analysis of the deflections of TCR clusters motion by substrate-imposed barriers reveals a cosine scaling of the speed, with a deflection angle and no elastic memory of trajectory.
An investigation is then carried out on the effect of vehicle models, vehicle speed, irregularity, guideway deflection ratio, span length, span continuity and damping ratio on dynamic responses of the relatively low speed maglev vehicle and guideway structures.
Attempts to understand the variability in SEP intensities have been focused on two aspects: (1) source factors involving CME properties, (2) environmental factors such as ambient magnetosonic speed, preceding CMEs, deflection by large-scale structures, seed particles, and turbulence.
Lee et al. [6] established a model of guideway beam with the modal superposition method, and studied the influence of some factors on the levitation gap and the dynamic magnification factor, such as the vehicle speed, irregularity, guideway deflection ratio, span length, span continuity, and damping ratio.
In this study, a high-speed air spindle composed of a carbon fiber epoxy composite shaft and two steel flanges was designed for maximum critical speed considering both the deflection due to bending load and the radial expansion due to centrifugal force and temperature rise during high-speed rotation.
