Published a new master course: Mechatronic System Design

Last week a new master course of Mechanical Engineering has been published: Mechatronic System Design.

mechatronic2

 

Course Contents

Mechatronic system design deals with the design of controlled motion systems by the integration of functional elements from a multitude of disciplines. It starts with thinking how the required function can be realised by the combination of different subsystems according to a Systems Engineering approach (V-model).

Some supporting disciplines, like power-electronics and electromechanics, are not part of the BSc program of mechanical engineers. For this reason this course introduces these disciplines in connection with PID-motion control principles to realise an optimally designed motion system.
The target application for the lectures are motion systems that combine high speed movements with extreme precision.
The course covers the following four main subjects:

Dynamics of motion systems in the time and frequency domain, including analytical frequency transfer functions that are represented in Bode and Nyquist plots.
Motion control with PID-feedback and model-based feedforward control-principles that effectively deal with the mechanical dynamic anomalies of the plant.
Electromechanical actuators, mainly based on the electromagnetic Lorentz principle. Reluctance force and piezoelectric actuators will be shortly presented to complete the overview.
Power electronics that are used for driving electromagnetic actuators.
The fifth relevant discipline, position measurement systems is dealt with in another course: WB2303, Electronics and measurement.
The most important educational element that will be addressed is the necessary knowledge of the physical phenomena that act on motion systems, to be able to critically judge results obtained with simulation software.
The lectures challenge the capability of students to match simulation models with reality, to translate a real system into a sufficiently simplified dynamic model and use the derived dynamic properties to design a suitable, practically realiseable controller.
This course increases the understanding what a position control system does in reality in terms of virtual mechanical properties like stiffness and damping that are added to the mechanical plant by a closed loop feedback controller.

It is shown how a motion system can be analysed and modelled top-down with approximating (scalar) calculations by hand, giving a sufficient feel of the problem to make valuable concept design decisions in an early stage.
With this method students learn to work more efficiently by starting their design with a quick and dirty global analysis to prove feasibility or direct further detailed modelling in specific problem areas.

Race Car Aerodynamics added to DUT Racing OpenCourseWare

Every year a multi-discplinary team of 90 students from Delft University of Technology design a new race car to compete in the Formula Student Competition.
The main goal of the team is education: giving prospective engineers the hands-on experience of developing and building an actual race car. Besides that they of course compete with their electronic 4WD car to win the Formula student competition, like they did in 2012 and 2013.

OpenCourseWare partnered with the DUT Racing team to publish a series of courses that show how the basic engineering education in Delft connects to the concrete DUT Racing engineering project.
This year special attention is paid to the aerodynamics of the DUT 14 race car. Dr. ir. Gerrit Elsinga from the Fluid Mechanics department explains the basics of Race Car Aerodynamics in two short video lectures.

Additionally, a number of courses that apply to the design of the DUT ’14 can be found under the following categories: Chassis, Vehicle Dynamics, Control Systems, Aerodynamics, Powertrain and Electronics.
The related OpenCourseWare, together with a short introduction on the category to which they are related, can be found under ocw.tudelft.nl/dutracing or http://dutracing.nl/explore-the-car/.

Published a new course: Traffic Flow Theory and Simulation

Just published a new master course Civil Engineering: Traffic Flow Theory and Simulation from the track Transport, Infrastructure and Logistics.

traffic flow

This course discusses fundamental traffic flow characteristics and traffic flow variables. Their definitions are presented, and visualization/analysis techniques are discussed and empirical facts are presented. The empirical relation between the flow variables and the bottleneck capacity analysis are discussed. Shockwave analysis and a review of macroscopic traffic flow models are presented. Traffic flow stability issues are discussed as well as numerical solution approaches. The lectures also show how macroscopic models are derived from microscopic principles. This course provides an overview of human factors relevant for the behavior of drivers. The car-following model and other approaches to describe the lateral driving task will be discussed. The lectures also pertains to general gap acceptance modeling and lane changing. Microscopic models for pedestrian flow behavior are discussed and an in depth discussion of microscopic simulation models will be presented. The study goals of this course are to gain insight into theory and modeling of traffic flow operations, to learn to apply theory and mathematical models to solve practical problems and to gain experience with using simulation programs for ex-ante assessment studies.
Keywords:Traffic flow, Fundamental Diagram, Pedestrian flow, Lane Changing, car-following model, Shockwave theory , lateral driving task.

Also, the OpenCourseWare Consortium announced a name change and will from now on carry the name ‘Open Education Consortium’. This name change resembles the widening of focus for the consortium from educational resources towards education and therewith better suits the globally changing interests of institutions.

published a new course: Integrated Water Management

Last week a new course from Water Management has been published in OpenCourseWare: Integrated Water Management

800px-SchiffeMaxau2

The lectures introduce a number of topics that are important for IWRM and the modeling exercise. The lectures introduce water management issues in the Netherlands, Rhine Basin, and Volta Basin. The role-play is meant to experience some of the social processes that, together with technical knowledge, determine water management
For the modeling exercise, the class will be divided in several groups of 5 to 6 persons. Each group will model a set of integrated water resources management issues and simulate possible development scenario’s. Two of the problem sets are:
1. Heating up of the Rhine due to climate change;
2. The effects of small reservoirs for irrigation in the Volta basin.
In addition, there is room for different cases, to be discussed during the first lecture.
The simulation exercise and the reporting should incorporate the concerns of the groups that are mostly affected by the issue and the groups that can contribute most to its resolution. The report on the modeling exercise should contain concrete recommendations.

The main modeling software to be used is WEAP, which has been developed by SEI-Boston. Students of CT4450 can use this software for the duration of one year.
Study Goals Definitions of Water Resources Management (WRM) tend to be rather broad and vague. This is how it should be, but in practice, the context and the problems at hand constrain
the engineer to such an extent that any particular case quickly becomes clear. WRM is always context dependent and should always be problem-driven. This explains why, just
as in Business Management, case studies play such an important role in teaching. The general framework or theory of WRM will receive less attention in this introductory
course.
