This paper deals with experimental modal analysis of bolted storage tank, commonly used in many applications such as sewage treatment. Experimental is crucial for the evaluation dynamic properties, which helps assessment wind-induced loads. Vortex shedding at specific wind speeds can excite natural frequencies, potentially causing damaging vibrations. Although tanks have a simple cylindrical shape, their construction from overlapping steel sheets, stiffening girders, and joints complicates...
Steel-wire rope is a mechanical component that has versatile uses and on which human lives depend. One of the basic parameters serve to describe its load-bearing capacity. The static capacity property characterized by limit force able endure before it breaks. This value depends mainly cross-section material rope. entire obtained in tensile experimental tests. method expensive sometimes unavailable due load testing machines. At present, another common numerical modeling simulate an test...
The auto-balancing mechanism is used in the spin-dry regime of laundry machine. high rotating speed and unbalanced mass inside drum create centrifugal force, which cause vibration. consists a set balls circular guiding track. During process, settle opposite position to an mass. force compensates one masses. paper deals with non-linear numerical simulation imbalance settlement following parametric study. solution problem demonstrated on industrial machine maximum capacity 7 kg dry 930 rpm....
Flexible structures are increasingly important in biomedical applications, where they can be used to achieve adaptable designs. This paper presents a study of the design and behavior 3D-printed lightweight flexible structures. In this work, we focus on principles numerical modelling spatial patterns, as well their mechanical properties under various loads. Contact surface fraction was determined ratio area printed pattern entire curved surface. The objective work is reducing contact develop...
Large-capacity bolted cylindrical tanks for liquid storage are used in many applications. The made of thin steel sheets that connected by bolts. A common problem associated with is deforming under extreme loads. Adding wind girders to the tank increases tank’s buckling capacity, which defined as limit load at structure loses stability. usually placed horizontal joints wall. bent from standard or non-standard bars a uniform cross-section. This type design difficult produce, especially large...
