Über dieses Buch

Anyone who wants to simulate the behavior of vehicles must think about how they want to model the vehicle's chassis. Depending on the question (vehicle dynamics, ride comfort, load data prediction ...) there are a variety of possibilities. This book should help to find and implement the right models and processes. In addition to a short introduction to simulation technology, the most important types of modelling for the assemblies of the chassis using the method of multi-body systems are presented. However, successful simulation does not only mean the assembly of suitable models, but always represents a well thought-out process that goes from data acquisition to the validation of the models. This will be discussed using suitable examples for concrete questions.

Introduction to Simulation

Frontmatter
1. Simulation Methods
Abstract
What is simulation in general, what are the essential methods for chassis simulation and which commercial tools are used there.
Dirk Adamski
2. Systems Engineering
Abstract
How are the kinematics and compliance of an axis implemented in the model. What is the role of measurements of elastomeric bearings and how do you determine the necessary parameters?
Dirk Adamski
3. Modeling
Abstract
Modeling is certainly the most complex and important task when it comes to simulating technical systems in general and vehicles in particular. All mistakes made in this phase are passed through all subsequent steps and thus cause considerable effort and corresponding costs. For this reason, one should take enough time for the modeling and proceed carefully. So-called quick-and-dirty solutions often lead to fast results, but their quality is often not sufficient to make decisions for the product.
Dirk Adamski
4. Numerical Analysis: The Problem with the Beginning
Abstract
What happens between starting the simulation and saving the results is for many a closed book. Most simulation programs offer the user the possibility to generate various calculation results completely without the knowledge of numerical analysis. A few basic concepts are discussed below.
Dirk Adamski
5. Simulation Tools
Abstract
What components does a simulation environment consist of and how do you bring different disciplines together?
Dirk Adamski
6. Simulation Process
Abstract
A simulation process consists not only of the actual calculation, but also of pre- and post-processing. How is it documented and archived, how is it ensured that the current calculations can be repeated exactly in a year?
Dirk Adamski

Simulation in Chassis Technology

Frontmatter
7. Modeling of Chassis Components
Abstract
A first overview of the use cases, which are discussed in the following and the question, how complex models should be and what belongs to planning calculations.
Dirk Adamski
8. Kinematics and Compliance
Abstract
How are the kinematics and compliance of an axis implemented in the model. What is the role of measurements of elastomeric bearings and how do you determine the necessary parameters?
Dirk Adamski
9. Springs
Abstract
How to model the differences between a coil spring and a leaf spring? What are the special features to be considered for air springs and buffers?
Dirk Adamski
10. Damping and Friction
Abstract
Dampers are an essential component of the chassis. How do you model them, how are the necessary data determined and how do you deal with the friction that can be found everywhere?
Dirk Adamski
11. Steering
Abstract
The steering train, i.e. the way from the steering wheel to the wheel and the concepts of power steering are described.
Dirk Adamski
12. Tires and Roads
Abstract
What are the general requirements for tire models and what is the difference between tire models for driving dynamics and those for ride comfort or load prediction? How do you get real roads into the computer?
Dirk Adamski
13. Drive Train
Abstract
How is the drive torque defined and how are engine, gears and differentials mapped?
Dirk Adamski
14. Brake System
Abstract
How is the functional chain from the driver's foot to the wheel brake defined and how is the braking torque applied? What is special about braking to a standstill and about the temperature behavior of the brake?
Dirk Adamski
15. Vehicle Body
Abstract
How can the body in white in a rigid body model be correctly represented and how are the load and passengers represented? For which load cases does the aerodynamics have to be considered?
Dirk Adamski
16. The Simulated Driver
Abstract
There are driver models of different quality for the implementation of the driver tasks of longitudinal and lateral guidance.
Dirk Adamski
17. The Vehicle Model as a Controlled System
Abstract
The development of modern assistance systems or automated driving is not conceivable without the support of simulation.
