ABSTRACT: An adjustable bed is a supporting structure designed to provide a seating
base or platform, for a 5.0 KW micro steam turbine generator plant prior to its
mounting on a block-type concrete foundation. The design of the bed frame and flanges was
carried out by considering the predetermined weights of the turbine and generator (alternator) [1]. On this basis, steel materials of U-channels and angle irons were used in the fabrication of the generator bed. The
bed was designed to be adjustable by accommodating direct coupling of the turbine
with the generator, and the belt drive. Fabrication was carried out by welding,
machining, and
assembly. During assembly, the bed
was made to accommodate damping materials in order to reduce the vibration of
the plant [2]. The performance of the unit with or without vibration isolator when
they are axially connected with flexible flange coupling or transversely
connected with sets of belt and pulley, in succession respectively. The results showed that a reduction in the force transmitted to the supporting
structure occurred when the vibration produced by the unit is isolated from its
base by the use of a vibration isolator, maximum reduction of 99.95%
achieved when axially coupled and 99.91% when transversely connected with belt
and pulley system [3].
