MATS2400 Hydraulics and Machine Systems Course description

In this course, students will gain theoretical and applied knowledge on industrial materials. The course begins with an introduction to the structure of atoms, electron configuration and the period table. The various bonds found in different material groups are described. An account of the different atomic arrangements is followed by the study of materials imperfections and their effect on properties. The course moves on to describe the different hardening mechanisms (strain hardening, solid solution hardening, dispersion hardening and precipitation hardening). In physical metallurgy, the use of phase diagrams is central to understand the microstructure of alloys and the design of heat treatments to obtain desired properties. In total, the chemistry content amounts to 1.5 credits.

The focus of this course is on construction materials, especially metallic materials such as steel and aluminum. However, references to polymers, ceramics and composites are provided for comparison. The course includes content about joining methods such as welding, soldering and bonding. Furthermore, it provides a good basis of the factors that affect materials selection for various applications and for assessing the environmental consequences of materials choices.

• Designing and dimensioning certain hydraulic systems.
• Calculating working pressure, volume flow and flow velocities in pipelines using Bernoulli's equation and continuity equation.
• Calculating pressure loss and power loss across different types of components in pipelines and finding the operating point of pumps operating in a composite system.
• Calculating power, torque, and different types of efficiencies for systems based on thermal and electrical energy machines.

General competence

The students will gain:

• The ability to produce adequate documentation of their own work.

Lectures, laboratory assignments and supervised exercises.

The estimated workload is four hours of lectures, four hours of supervised exercises and five hours of self-study per week.

The following coursework is compulsory and must be approved before the student can sit in the exam:

• 1 project assignment
• 2 lab reports;
• 3 individual exercises

The following coursework is compulsory and must be approved before the student can sit the exam:

• 2 approved written lab reports. Time per lab is approx. 6 hours including preparation and report writing. The reports are delivered on Canvas.

A supervised three-hour individual written exam.

The exam result can be appealed.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed.

A handheld calculator that cannot be used for wireless communication. If the calculator’s internal memory can store data, the memory must be deleted before the exam. Random checks may be carried out.

Grade scale A-F.

One internal examiner. External examiners are used regularly.
