EXCITE Timing Drive is used in the design and
analysis of valve trains to meet the requirements of
dynamics and durability whilst reducing friction and
noise excitation.
The output shows the dynamic components of all
modeled valve train elements. The periods of
contact loss between single valve train elements,
the dynamic behavior during valve open phase,
and impact forces at valve closing can be
determined. The results include the excitation
forces causing vibration and noise of the engine
structure.
Therefore, the results can be used to assess
modifications of cams and valve trains with respect
to dynamic loads, valve timing and noise due to impacts in the valve train.
The real valve train is described by a lumped mass system. Because of the non-linearity, the dynamic
behavior (motion, forces) of the elements of this system is calculated in time domain by step-by-step
integration using a second order Predictor/ Corrector method.
Calculated are the dynamic paths, velocities, accelerations, and forces in the valve train elements.
Cylinder pressure, friction at various elements and speed irregularities of the camshaft can be
EXCITE Timing Drive provides generic elements (rigid body, general connections) and specific
elements. Generic elements are used to perform more detailed analyses of valve trains, timing drives
or parts of overall systems if required, as well as to investigate new design concepts and to simulate
other kinds of mechanical systems. Specific elements are prepared to cover common valve train
components. They require a reduced amount of input data and can easily be used for most usual timing
