Research on cutting vibration characteristics of face-milling involute gear
Defence Technology, 2017 Traditional machining methods, such as gear hobbing, gear shaping and gear milling, etc, are commonly used for cutting machining of gear tooth profile, which cannot meet huge machining demand of gears to a certain extent. This article proposes to utilize

Strain-Rate Frequency Superposition in Large-Amplitude Oscillatory Shear
, 2010 In a recent work, Wyss, {\it et.al.} [Phys. Rev. Lett., {\bf 98}, 238303 (2007)] have noted a property of `soft solids' under oscillatory shear, the so-called strain-rate frequency superposition (SRFS).

The Resonator Banjo Resonator, part 2: What makes them really crack? [PDF]
, 2015 A simple experiment quantifies the difference between the sound production of a banjo with and without a resonator back. Driven by a small tweeter mounted inside the pot, for frequencies above about 4500 Hz, the produced external sound is 6 to 10 dB ...

Flutter Clearance of the F-14A Variable-Sweep Transition Flight Experiment Airplane, Phase 2 [PDF]
An F-14A aircraft was modified for use as the test-bed aircraft for the variable-sweep transition flight experiment (VSTFE) program. The VSTFE program was a laminar flow research program designed to measure the effects of wing sweep on laminar flow.

Estimation of natural frequency for nonlinear mechanical retention of printed circuit board
Scientific ReportsVibrational performance for a structure, in majority of the cases, is estimated/ predicted using frequency domain solvers. Linearity and Time-invariance are imposed onto the structure for solving in frequency domain.
