Balance of Reciprocating Masses- Engineering Lab Training Systems.
Technical Description
Using the benchtop model, mass forces
can be investigated on a reciprocating piston machine. The model has
four pistons with plastic sleeves that do not require lubrication. The
quadruple cranked crankshaft is driven by an electronically commutated
DC motor via a toothed belt. The rotational speed is regulated and
displayed digitally. Forces and moments are measured using strain gauges
on the elastic boom of the model mounting bracket. All electrical
functions are integrated into the control unit that also provides an
analogue output for an oscilloscope. The crank offset for each cylinder
can be continuously adjusted, as an aid marks are provided at 90°, 180°
and 270°. The natural frequencies are defined such that resonant
oscillations are easy to detect even without instrumentation.
