Robot Vibration Control Using Inertial Damping Forces

Measurement of noise and vibration in Canadian forces armoured vehicles.

Noise and whole-body vibration measurements were made in the following Canadian Forces vehicles: LAV III, Bison and M113A2 ADATS (air defence anti-tank system). Measurements were made at different crew positions while the vehicles were driven at different speeds over rough terrain and paved roads. The participants completed a questionnaire at the end of each measurement session on their reactio...

Experimental Research and Analysis of Vortex Excited Vibration Suppression of Spiral Stripe Strake

this paper carries out the experimental research and analysis on the vortex-excited vibration suppression effect of the spiral stripe strake via the laser particle velocimeter (PIV) under vortex speed U=0.6 m/s and attack angle α=300 and discusses the VIV suppression mechanism of the spiral stripe strake by using the numerical simulation of the computational fluid dynamics (CFD) in order to obj...

Determination of axial forces by local vibration measurements

This article proposes a method to estimate the axial force in a bar based on local vibration measurements. The method assumes Timoshenko beam theory and in addition accounts for the rotational inertia of the bar and the mass of the sensors. A major advantage of the proposed method is its generality. Assuming at least five sensors along the length of the bar, no information on the connection of ...

Microscopic Structures Analysis and Experimental Research of Beak

To reveal the mechanism of the easy discretization and low damage in kernel dispersal, this paper analyzes the microscopic analysis of beak structures and finds that maxillary outside cells of the beak are dense and hard. Besides, the cuticle wrapping on maxilla of chicken's beak can reduce corn kernels damage in the discrete process of ear. From force test of corn ear, we find that value of x ...
