Harmonic damper

Index Harmonic damper

A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. [1]

Balance shaft

In piston engine engineering, a balance shaft is an eccentric weighted shaft that offsets vibrations in engine designs that are not inherently balanced.

Crankshaft

A crankshaft—related to crank—is a mechanical part able to perform a conversion between reciprocating motion and rotational motion.

Damping ratio

Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations.

Engine balance

Engine balance refers to those factors in the design, production, engine tuning, maintenance and the operation of an engine that benefit from being balanced.

Frederick W. Lanchester

Frederick William Lanchester LLD, Hon FRAeS, FRS (23 October 1868 – 8 March 1946), was an English polymath and engineer who made important contributions to Automotive engineering and to Aerodynamics, and co-invented the topic of operations research.

Harmonic oscillator

In classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x: where k is a positive constant.

Henry Royce

Sir Frederick Henry Royce, 1st Baronet, OBE (27 March 1863 – 22 April 1933) was an English engineer and car designer who, with Charles Rolls and Claude Johnson, founded the Rolls-Royce company.

Interference fit

An interference fit, also known as a press fit or friction fit is a fastening between two parts which is achieved by friction after the parts are pushed together, rather than by any other means of fastening.

Internal combustion engine

An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.

Mass

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.

Noise and vibration on maritime vessels

Noise and vibration on maritime vessels are not the same but they have the same origin and come in many forms.

Q factor

In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its centre frequency.

New!!: Harmonic damper and Q factor · See more »

Resonance

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies.

Straight-eight engine

The straight-eight engine or inline-eight engine is an eight-cylinder internal combustion engine with all eight cylinders mounted in a straight line along the crankcase.

Torsional vibration

Torsional vibration is angular vibration of an object—commonly a shaft along its axis of rotation.

Transmission (mechanics)

A transmission is a machine in a power transmission system, which provides controlled application of the power.

Tuned mass damper

A tuned mass damper, also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce the amplitude of mechanical vibrations.

Vibration

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.
