For the last two decades, an extensive transition in automotive X-in-the-loop activities from isolated electronic control units to real-time related, geographically distributed validation tasks has occurred. Benefits are strengthening frontloading, enabling concurrent engineering and reducing prototypes testing efforts. As a downside, comprehensive system understanding adequate simulation models must be provided. New technological trends like software-over-the-air-updates denote continuous...

The use of elastomers in modern road vehicles can solve many design conflicts the development process. prerequisite for this is a detailed calculability component properties, which are dependent on geometric shape, choice material and parameters manufacturing A robust method calculating parameter-property relationships elastomer bushings based physical models machine learning approaches allows these to be calculated early phases vehicle development. Viscoelastic properties represent major...

Pervasive applications of the vehicle simulation technology are a powerful motivation for development modern automobile industry. As basic parameters road vehicle, dynamic can significantly influence ride comfort and dynamics therefore have to be calculated accurately obtain reliable results. Aiming develop general solution, which is applicable diverse test rigs with different mechanisms, novel model-based parameter identification approach using optimized excitation trajectory proposed in...

In this work, a method is developed for the component design of chassis bushings with contoured inner cores, aided by artificial neural networks (ANNs) and optimization. First, model physical bushing generated using finite element (FEM). To determine material parameters model, parameter optimization conducted. Based on different samples study are experiments method. Due to invalid areas geometrical definitions, constraints established space cleaned up. From space, database several three...

With the continuous digitalization of vehicle development process, virtual design methods play an increasingly important role. Representative load profiles, which can be determined for example with aid multi-body system simulation, are required reliable and validation complex elastomeric bearings such as engine mounts conventional electrified drive trains. Due to material properties designs today's elastomer hydro mounts, representation these components is a challenging task. In already...

This work presents a new systematic solution to identify the vehicle inertia parameters which are essential inputs for simulation and safety research. In conceptual design phase of this work, virtual three Degree-of-Freedom (DoF) test bench/ parallel manipulator (PM) whose moving platform is used clamp under developed. order realize kinematic characteristics proposed PM, analysis consists inverse singularity architecture carried out. Aiming at obtaining all ten (i.e., mass, center gravity...

"Elastomeric bearings are used inter alia for load transfer, vibration isolation and damping in different areas the motor vehicle. To ensure that these functional properties maintained despite high loads over life of vehicle, components tested with highly complex time-consuming test cycles. Multi-axial high-dynamic three translative or rotational directions currently correspond to state art. These cycles require performance technology. Due increasing number vehicles drive variants ever...
