The monitoring of cutting force components is one the possibilities to control machining processes from point view its stability, machine tool spindle or loading. This paper presents and compares results experimental longitudinal sawing pine wood with 4 saw discs different teeth number (16 24) rake angle (10° 20°) during up (conventional) down (climb) revolutions (4000 min-1, 5000 6000 min-1) f...

This study designs and fabricates a novel integrated digital hand grip dynamometer and analyzes collected grip strength data. The dynamometer directly stores collected data in a computer, unlike those on the market that cannot directly store information. A strain gauge load cell is used as a force sensor. The dynamometer is designed to maximize ergonomics. Excitation voltage of the load cell is...

The influence of muscle fiber motion during exercise on diffuse correlation spectroscopy (DCS) measurements of skeletal muscle blood flow is explored. Isotonic (with muscle fiber motion) and isometric (without muscle fiber motion) plantar flexion exercises were performed at 30% of maximal force on a dynamometer, and muscle blood flow was continuously monitored on the medial gastrocnemius (calf)...

The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, light-duty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included regulat...

A conventional dynamometer (the most common type of measuring device in rod pumping well analysis) records polished rod loads versus rod displacement during the pumping cycle on a plot called dynamometer card. Calculations requiring rod loads and displacements as input variables must rely on information retrieved from these cards. There are many conditions that prevent the pumping analyst from ...

The inertia and resistance of a wheelchair dynamometer must be determined in order to compare the results of one study to another, independent of the type of device used. The purpose of this study was to describe and implement a dynamic calibration test for characterizing the electro-mechanical properties of a dynamometer. The inertia, the viscous friction, the kinetic friction, the motor back-...
