The durability of a machine structure is based on its mechanical performance through entire service life. To avoid structural failures in machines, it standard design practice that machines be analyzed the types loading (static and fatigue) associated with order to safe dependable structures. These analyses are performed purpose estimating behavior parts under specific operational conditions. a...

The more frequent mining activities are carried out, the deeper tin on seabed, therefore many ship owners want to increase length of ladder production suction vessels. owner KIP Timah 8 boat will 70 meters, which previously was only 58 meters. paper research response structure before and after being extended, limit strength in pulley area, then ultimate longitudinal due vertical bending moment....

Magnetic fluid seal is a new type of sealing method, which has been applied in many fields. For some fields, such as aviation and aerospace, high performance, large shaft diameter, small design space are required, brings difficulties to the design. Therefore, it necessary study diameter magnetic with thin-wall parts. In this article, effects clearance deflection on field distribution analyzed b...

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...

UNLABELLED The flying feathers of birds are keratinous appendages designed for maximum performance with a minimum weight penalty. Thus, their design contains ingenious combinations of components that optimize lift, stiffness, aerodynamics, and damage resistance. This design involves two main parts: a central shaft that prescribes stiffness and lateral vanes which allows for the capture of air. ...

Plain bearings are undoubtedly one of the main parts power machines (such as a turbine or compressor). However, there many cases when in large equipment is occurring asymmetrically loading on due to thermal deformations, production inaccuracies, simple deflection shaft. Presented research deals with numerical analysis levers being first step at design new self-equalizing thrust bearing goal fin...

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 ...

Turbo generator shafts are often subjected to cyclic torsion resulting in formation of large longitudinal cracks as well as circumferential cracks. The presence of these cracks could greatly impact the shaft resonance frequencies. In this paper, dynamic response of a shaft with longitudinal and circumferential cracks is investigated through a comprehensive analytical study. The longitudinally c...
