Parametric study on thrust force of core drill

Journal of Materials Processing Technology, 2007
Abstract Drilling-induced delamination is among the major concerns of applying the fiber-reinforced composite materials in various industries. Core drill possesses the advantage for reducing the delamination by distributing the drilling thrust force toward the drill periphery.

Identification of thrust force models for vibratory drilling

International Journal of Machine Tools and Manufacture, 2009
Abstract Among the scientific problems in drilling, determining thrust forces for any drill geometry and any workmaterial remains an issue. This question is especially critical in the context of the self-vibratory drilling (SVD) technology, since thrust force governs the trajectory of cutting lips.

The Traceable Calibration of Thrust Stand by Electrostatic Force

Journal of Visualized Experiments, 2022
Micro thrusters have important applications in low-frequency gravitational wave detection, satellite formation, and inter-satellite laser communication, so it is necessary to accurately measure the thrust of micro thrusters with traceability. A thrust stand is a widely used micro thrust measuring device with the advantages of high resolution and large ...

Thrust Forces in Underwater Swimming

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1965
Instantaneous and mean static thrust levels were measured for eight underwater swimmers restrained in a submerged force platform. Swimming was examined barefoot and with two types of fins. The main beneficial effect of the fins was to eliminate the substantial negative thrust component associated with barefoot swimming.

Measuring Leg Thrust Forces in the Common Starling

Journal of Experimental Biology, 1996
ABSTRACT We describe the design of a force-transducing perch which measures the reaction forces of small birds taking off and landing. In common starlings, landing forces are lower than take-off forces, because the bird may decelerate prior to landing by using its wings.

Design of a linear vernier permanent magnet machine with high thrust force density and low thrust force ripple

2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017
This paper introduces a novel linear vernier permanent magnet machine (H-LVPMM) with high force density and low force ripple. The permanent magnets (PMs) on secondary uses Halbach array, which can provide a larger flux density in the air gap than that of the conventional surface-mounted PMs configurations, and the primary is composed of three modules ...

Cranial tibial thrust: A primary force in the Canine stifle

Journal of the American Veterinary Medical Association, 1983
SUMMARY A cranially directed force identified within the canine stifle joint was termed cranial tibial thrust. It was generated during weight bearing by tibial compression, of which the tarsal tendon of the biceps femoris is a major contributor, and by the slope of the tibial plateau, found to have a mean cranially directed inclination of 22.6 degrees.

Balanced-force-control of underactuated thrust-propelled vehicles

2007 46th IEEE Conference on Decision and Control, 2007
The paper sets the basics of a control framework for underactuated thrust-propelled vehicles immersed in a fluid, with the objective of stabilizing reference trajectories either in velocity or in position.

Dynamic Modeling of the Thrust Force and Torque for Drilling

1992 American Control Conference, 1992
Discrete time dynamic models relating the drilling process outputs of thrust force and torque to feed input are presented in this paper. Drilling to depths of greater than a few drill diameters with conventional twist drills, the torque and thrust force tend to increase due to difficulties with chip evacuation.
