The harmonic damper is also known as harmonic balancer as it assists in balancing the engine and reduces the
torsional vibration in the crankshaft of the internal combustion engines.
Users can perform
torsional vibration measurements autonomously with the RASdelta data logger without having to rely on a connected computer.
Vispiron Rotec is already known for its
torsional vibration analysis technology.
This module's building blocks include engine mount, crankshaft, bearing, flywheel,
torsional vibration damper and balancing shaft.
Only the fifth order mode showed
torsional vibration. The second, fifth and sixth order modes indicated that the vibration of pre-stressed concrete beam was severe mainly on the top.
Two different combinations for [C.sub.e1] and [C.sub.e2] are selected for preload engaging: one is the high
torsional vibration excitation [C.sub.e2] with respect to preload [C.sub.e1], in which the amplitude of [C.sub.e2] is assigned to 6 Nm, 8 Nm, and 10 Nm, respectively, and [C.sub.e1] is set to 3.34 Nm; the other is low
torsional vibration excitation [C.sub.e2] with respect to preload [C.sub.e1], in which the amplitude of [C.sub.e2] is assigned to 6 Nm, 8 Nm, and 10 Nm respectively, and [C.sub.e1] is set to 16.8 Nm.
Physical environments like fluid flow or biological tissue can be modelled as a viscoelastic medium, which has damping and elastic characteristics, and the effect to the
torsional vibration of CNT is a very interesting topic for researchers.
As the guideline developed, a need for better reciprocating compressor
torsional vibration analysis guidelines was also identified.
