Mea­sure­ments on com­plete vehi­cle / VEHI­CLE DYNAM­ICS

Prob­lem: Dynam­ic and acoustic prob­lems, res­o­nances

Goal: Sup­port for opti­mal design of the dri­ve train, noise reduc­tion

A holis­tic view is nec­es­sary for the eval­u­a­tion and opti­miza­tion of the vehi­cle. Dynam­ic effects, acoustic behav­ior, influ­ences on dri­ving behav­ior and inter­ac­tions in the sys­tem con­text should be con­sid­ered. To be more pre­cise, tor­sion­al vibra­tion exci­ta­tions, mass iner­tias, stiff­ness­es and damp­ing behav­ior of the com­po­nents play an impor­tant role in the dynam­ic design of the pow­er­train. They can cause res­o­nances and dynam­ic prob­lems that affect com­po­nent life. Anoth­er impor­tant devel­op­ment objec­tive is noise reduc­tion in clutch­es, trans­mis­sions, and dri­ve shafts. There­fore, an in-depth inves­ti­ga­tion of the inter­ac­tions of the indi­vid­ual com­po­nents is essen­tial.

In the fig­ure, a mul­ti-chan­nel speed mea­sure­ment using mag­ne­to-resis­tive sen­sors and laser sen­sors, for exam­ple on car­dan shafts (KW), dri­ve shafts (AW), cou­plings (K0, K1), elec­tric motors (E0‑4) and trans­mis­sions, in com­bi­na­tion with ana­log mea­sured vari­ables such as accel­er­a­tions and sound pres­sure, pro­vides a com­pre­hen­sive over­all pic­ture of the vibra­tion behav­ior of the pow­er­train. The record­ed mea­sured val­ues are eval­u­at­ed in the time and spec­tral domain. The acoustic behav­iour is also ana­lyzed.
