A typical passive magnetic bearing has been modeled and analyzed for its performance characteristics. The magnetic bearing studied in this work comprised of a Shaft, inner magnets sleeved over the shaft, and outer magnetic rings. A detailed analysis has been perform on the force exerted by a permanent magnet on the shaft nurture to restore the shaft to its equilibrium position when an eccentric...

We have assessed, in vitro, the effect of KTP laser strike on the reinforced laryngeal mask airway (RLMA) under a variety of conditions. At power densities normally encountered in clinical practice, using a divergent KTP laser beam, the RLMA could not be penetrated and did not ignite with laser strike. The RLMA was penetrated at a high power density of 6.94 W mm-2 after 45-60 s. A flame appeare...

Fretting damage phenomenon often appears in the interference fit assembly. The finite element model of hollow shaft and shaft sleeve was established, and the equivalent stress and contact stress were computed after interference assembly. The assembly body of hollow shaft and shaft sleeve was in whirling bending load, and the contact status (sticking, sliding, and opening) and the distribution o...

Water tank is used extensively for storing water, inflammable liquids and other chemicals. Generally, to provide water at large, tank is supported on frame or shaft (a vertical cylindrical shell). The staging with a single row of columns placed straight (vertical) along the periphery of circle or shaft, are generally adopted for elevated water tanks to support the tank container. Apart from ver...

Abstract—This paper explain the primary balancing of single cylinder engine and optimizing the counter balancing mass to reduce the unbalanced forces coming on the crankshaft. After optimizing, the effect of primary balancing is validated. After primary balancing, the vibration is measured on the engine at various locations. Balancer shaft is designed for the unbalanced forces exist after prima...

This paper describes the calculation of torqueina brushless permanent-magnet line-start a.c. motor by means of the ~~UX-MMF diagram in combination with the finite-element method. Results are compared with measured ~~UX-MMF diagrams, with shaft torque measurements, and with torque calculated using the classical phasor diagram.

Treatment of tibial shaft fractures is still discussed controversial. In the present study current literature was reviewed with the objective to demonstrate current recommendations concerning tibial shaft fractures. Tibial shaft fractures are often caused by high-energy trauma with severe concomitant soft-tissue injuries. Solid bone union without hypertrophy, fast mobilization and full range of...

abstract   background: fractures of the tibia are important for their commonness and controversy in their management. both conservative and surgical techniques have been introduced in an effort to speed time to :::::union::::: while minimizing the occurrence of complications. standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. the purpose ...
