Název v původním jazyce

Elasto-kinematic computational model of suspension with flexible supporting elements

Popis výsledku v původním jazyce

This paper analyzes the impact of flexibility of individual supporting elements of independent suspension on its elastokinematic characteristics. The toe and camber angle are the geometric parameters of the suspension, which waveforms and their changes under the action of vertical, longitudinal and transverse forces affect the stability of the vehicle. To study these dependencies the computational multibody system (MBS) model of axle suspension in the system HyperWorks is created. There are implemented Finite Element Method (FEM) models reflecting the flexibility of the main supporting elements. These are subframe, the longitudinal arms, transverse arms and knuckle. Flexible models are developed using Component Mode Synthesis (CMS) by Craig-Bampton. The model further comprises force elements, such as helical springs, shock absorbers with a stop of the wheel and the antiroll bar. Rubber-metal bushings are modeled flexibly using nonlinear deformation characteristics. Simulation results are validated by experimental measurements of geometric parameters of real suspension.
