This course aims to provide students with insight into how advanced computer aids through an extensive integration can be utilised to reduce lead times while increasing efficiency and quality in development and design projects. Such aids are introduced in this course for the following activities: modelling, analysis and optimisation of non-linear static and dynamic systems optimization through concrete design tasks and examples from industry and the research world. This course also covers optimization methods suitable for complex combinations of phenomena and meta-modelling.
Knowledge and understanding
For a passing grade the student must
• be able to analyse, as well as motivate the choice of
analysis type, meta-model and optimization method for a complex
problem exposed to non-linear static or dynamic structural loads,
flow and/or thermal loads.
• be able to create an analysis model based on the chosen
analysis type
• be able to introduce necessary boundary conditions into the
analysis model
• execute the actual analysis program
• be able to evaluate the analysis and optimization results
achieved and suggest possible changes in the existing design
solution
• be able to communicate the process as well as the results of
the analysis/es orally and in writing
Competences and skills
For a passing grade the student must
• based on the assignment description, carry out a complete
analysis and optimization of a design solution loaded non-linearly
statically or dynamically – structurally, thermally and/or
involving any form of flow.
• have acquired the kind of insights into the methods, technics
and terminology regarding current computer based analyses so that
the student is able to communicate his or her results to an
industrial company verbally and in writing based on his or her
analyses
Judgement and approach
For a passing grade the student must
• be able to reflect on the results achieved and suggest possible further analyses and/or design changes in the original design solution
The main emphasis of the course is on non-linear design analysis. Design analysis in this context primarily concerns the utilisation of computer based analysis methods/techniques for quantitative problem solving in the design process. The finite element method (FEM) is primarily dealt with and methods and techniques for the analysis of non-linear static and dynamic mechanical systems. The course also deals with how computationally expensive analyses can be completed by metamodeling in order to enable time-efficient optimization.
The current software programs are ANSYS, WorkBench, Autodesk CFD, modeFRONTIER and PTC. Modelling is a crucial element in the analysis activity, in which the goal is a transfer of the technical solution that has been developed in a usable form for the subsequent operations. Structural analysis, thermal analyses and CFD analyses of non-linear and/or dynamic phenomena are becoming increasing more common in product development in order to optimally simulate the product’s actual environment and characteristics. The lectures are focused on modelling and selection of analysis type, as well as showing industrial applications. Guest lecturers with deep insights in specific techniques will be invited. Each student is expected to solve and submit a modelling and analysis assignment.
Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: For a final passing grade the student must pass an individual assignment. The assignment can be resubmitted with improvements if the student does not receive a passing grade the first time, but the student will only receive the minimum passing grade (G).
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
