Mathematical Methods in Dynamics and Durability

 

The department »Mathematical Methods in Dynamics and Durability« is concerned with modeling and simulation of usage variability, dynamic loading and energy efficiency of vehicles and machines.

We are developing statistical methods for durability, reliability and energy efficiency. Our software development project »virtual measurement campaign« combines statistical and simulation methods with geo-referenced data in a unique novel way.

Related to this our system simulation activities focus on »driver-vehicle-environment interaction«. We are developing models and software for tire simulation, ground interaction and invariant system excitation. Using our robot based driving simulator we are developing advanced driver and operator models.

Further we are simulating the mechanical behavior of highly deformable structures such as tires, rubber- and hydro mounts, cables and hoses.  We develop methods which allow for modeling the non-linearity correctly at a calculation performance suited for system simulation or interactive assembly simulation applications.

 

Fields of Activity

 

Usage Variability and Loading Statistics

Statistical methods play a key role in the design process and assessment of mechanical components with regards to fatigue strength or reliability.

 

Durability and Reliability

Reference loads, which have been derived on system level, need to be cascaded to subsystem and component level in order to optimize and release components.

 

System Simulation

The fatigue life estimation of components essentially relies on the stresses and strains induced by the loads acting on the component.

 

Human-in-the-Loop Driving Simulator RODOS®

We have designed an interactive motion simulator based on an industrial robot to facilitate complex simulations.

 

Nonlinear Structural Mechanics

We deal with modeling and simulation of highly deformable components and structures such as tyres, rubber bushings, air springs, cables and hoses.

 

CDTire - Tire Models

CDTire is a physical tire model family with different physical models for belt, sidewall and tread and supports engineers in almost all analysis scenarios used in modern vehicle development processes from within Multi-Body Simulation tools.
