MIT OpenCourseWare (OCW) Free Physical Sciences Infor Information control Information Theory Nutrition Vectors

This course is taught in four main parts. The first is a review of fundamental thermodynamic concepts (e.g. energy exchange in propulsion and power processes), and is followed by the second law (e.g. reversibility and irreversibility, lost work). Next are applications of thermodynamics to engineering systems (e.g. propulsion and power cycles, thermo chemistry), and the course concludes with fundamentals of heat transfer (e.g. heat exchange in aerospace devices).

The basic objective of Unified Engineering is to give a solid understanding of the fundamental disciplines of aerospace engineering, as well as their interrelationships and applications. These disciplines are Materials and Structures (M); Computers and Programming (C); Fluid Mechanics (F); Thermodynamics (T); Propulsion (P); and Signals and Systems (S). In choosing to teach these subjects in a unified manner, the instructors seek to explain the common intellectual threads in these disciplines, as well as their combined application to solve engineering Systems Problems (SP). Throughout the year, the instructors emphasize the connections among the disciplines.

Course Summary

In this first part of Vehicle Dynamics, we illuminate the longitudinal dynamic aspects of vehicles.

Clear and brief: acceleration and braking.

In Detail: After an introduction, we will look at driving resistances and slip, explain the demand of power and limits of a car, then clarify the needs for a clutch and gears and look at the rear and front weights during acceleration and braking. The course will be finished by two applications from automotive mechatronics.

By the end of the course you will …

  • understand basic principles of accelerating and braking a car.
  • know the driving resistances and their influences on vehicle dynamics.

Course Summary

In this second part of Vehicle Dynamics, we will illuminate the lateral dynamic aspects of vehicles.

Clear and brief: the cornering of a car.

In Detail: We will start with a simple single-track model and then describe the slip angle of a wheel. The slip angle results in cornering forces, which are essential for understanding lateral dynamics. After that, we will look at the dependency between longitudinal and lateral forces using Kamm’s circle and Krempel’s diagram. Then we will investigate steady state cornering, stability and the influence of different weight distributions between inner and outer side wheels of the car. The course will finish with two applications from automotive mechatronics.

What will I learn?

At the end of the course you will …

  • understand basic principles of cornering of a car.
  • know slip angle and cornering forces.
  • understand the single track model.
  • understand the steady state cornering, stability and the influence of different weight distribution between inner and outer side of the car.

Course Summary

In this third part of Vehicle Dynamics, we will illuminate the vertical dynamic aspects of vehicles. In short, we will describe the elements involved when a car drives on a bumpy or rough street.

We will start with a survey of suspensions and springs and dampers. After this, we will explain the description of rough streets and give an introduction to Fourier integrals. Next, we will take a closer look at vertical models. In the last fundamental part of the course, we will describe the conflict between driving safety and comfort. The course will be finished with two applications from automotive mechatronics.
