# Mathematics for Vehicle Engineering

The division »Mathematics for Vehicle Engineering« consists of the two departments »Dynamics, Loads, and Environmental Data« (DLU) and »Mathematics for the Digital Factory« (MDF) as well as the Tire Simulation project group and a cross section unit called MF-Technikum, which is responsible for testing and measuring systems.

#### Dynamics, Loads, and Environmental Data

In the department Dynamics, Loads and Environmental Data we develop methods and tools for system simulation including environmental data and usage variability. Thus we address the vehicle development attributes durability, reliability, energy efficiency and ADAS/AD. In line with this, we focus our system simulation activities on vehicle-environment-human interaction and develop tire simulation models and methods for invariant system excitation.

#### Mathematics for the Digital Factory

The Department Mathematics for the Digital Factory focusses on the development of software tools for virtual product development and product creation. Our software product IPS Cable Simulation, developed jointly with the FCC in Gothenburg, supports design, digital assembly and digital validation of cables, wiring harnesses and hoses. Additionally, our IPS IMMA tool is a digital human model developed to facilitate digital optimization of assembly processes

## Fields of Activity

### Digital Environmental Data

Statistical methods play a key role in the design process and assessment of mechanical components.

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.

### Dynamics and System Simulation

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

### Digital Human Models and Human-Machine Interaction

Our developed methods and algorithms are used to evaluate the dynamic movements of workers in production.

### Cables, Hoses and Flexible Structures

We deal with modeling and simulation of flexible, highly deformable components and structures such as tubes, cables and hoses as well as flexible surface-like parts.

### 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.
