Course content

This subject focuses on products' mechanical functions and how these are treated in a design process. The course consists of 12 modules Concepts and terminology (B&T) B&T related to design B&T related to mechanics B&T related to mechanical functions Technological basis 1 Mechanics and statics Newton's laws of motion Analysis of forces and moments Basic use of equilibrium equations Free body diagrams Basic statics Basic stability theory Technological basis 2 Friction Flatter Forces affecting friction Coulomb's law of friction Rolling and sliding friction Adhesive friction Abrasive friction Technological basis 3 thermal conditions Lover of thermodynamics Behavior of materials under thermal influence Thermal engineering material parameters Mechanical components 1 Fasteners Bolts and screw connections Rivet joints Resilient mechanisms and clips Mechanical components 2 Bearings and guides Rotary bearing Linear bearings Actuators Technical systems 1 Transmissions Exchange ratio Gears and gears Belt drive Chain operation Technical features 2 Simple mechanisms Oscillatory mechanisms Step mechanisms Transforms linear motion into rotation Transforms rotation into linear motion Reciprocating mechanisms Technical features 3 Higher order mechanisms Kinematic analysis of 4 strut mechanism Grashof's criterion Mechanisms and products Analyzer and implementation Examples Testing and evaluation Form and function

Learning outcome

Students must develop an understanding of concepts and terminology related to mechanical systems. The students must have an understanding of the technological principles that apply when a mechanical function is to be designed into a product. An understanding of how forces and moments act in products and mechanisms. The students must gain an understanding that materials in themselves are a limitation and an opportunity when designing mechanical systems. The students must understand the effect and use of various mechanical components and how such components can be used in a design process. The students must be able to choose different solutions and components with the intention of being able to design mechanisms of different types. The students must be able to carry out simple analyzes of mechanisms and movements. This subject should provide a basic understanding and knowledge of the integration of mechanical functions during a design process

Learning methods and activities

Lectures are mainly given in the laboratory, or associated area. All lectured material is available as film clips which students can go through as needed. The subject is relatively lab-intensive. The course is divided into modules where a module has the following components Lectures and Video lectures Short sessions max 30 min One compulsory exercise and/or laboratory exercise per module All student-active forms of learning are supported by student assistants or systems for fellow student evaluation Learning is always linked to practical problem solving so that there is little time between learning and working with exercises and/or lab exercises Exercises and lab exercises are carried out in groups Exercises and or lab exercises must basically be followed up along the way with guidance and approval must take place shortly after submission Exercises and lab exercises are compulsory and are evaluated as Pass / Fail Two attempts are allowed 80% of exercises/lab exercises must be approved before the exam The exam is a 4-hour written exam

Further on evaluation

The students are divided into groups. (Group division is done at the start of the semester and is a program-controlled activity and therefore not directly linked to this subject.) Work log is delivered with each submission All modules have an associated compulsory activity that must be carried out in groups immediately after the lecture/instruction. This can be a mandatory submission or a lab exercise (where the submission is the lab report). Submissions are given with a deadline of one week after the lecture has been completed. In the event of a "failure", the opportunity is given for a new attempt Of the mandatory work requirements, 80% must be passed in order to sit for the exam The exam is a 4-hour written individual exam conducted in Inspera. Allowed aids are Pre-specified and/or printed aids Simple calculator
