Abstract:
Torsional finite elements for direct, branched and grounded (boundary) connections and geared
connections with rigid or elastic tooth mesh are presented. The use of these elements for developing
dynamic models of various passenger vehicle powertrains is illustrated and discussed. A six-degree-offreedom
dynamic model for clutche ngagement is used to investigate the effect of low-frequency transients
on clutchengagem ent stick–slip and gear backlashin powertrains. Results for free vibration analysis and
transient vibration numerical simulations are presented. Attention is paid to the algorithms used in the
piecewise nonlinear transient analysis and the method of numerical simulation. The methodology is
thoroughly detailed and is discussed for application to higher degree-of-freedom powertrain models.
