2019-06-17 NMBO/ Daniel Haraldsson & Marcus Svensson / Design Optimization using Simulation Driven Design 2

Agenda

Title and Content

• Investigate implementation of design optimization

• Method development for design optimization

• Show the potential on how better initial design proposals could be created

• In a Design engineer perspective


Purpose of the thesis

Title and Content

Topology optimization

Optimize material layout within a given design space


What is optimization?

An optimization problem is the problem of finding the best solution from all feasible solutions

Shape optimization

Optimize a shape by exploring designs with different set

of parameter values

Title and Content


Identify & Define

I. Product follow-up project

II. Potential improvements regarding component weight

III. Design engineers & FE-experts

IV. Plan the execution

The question to be answered after Phase 1:

Is the potential of performance improvements worth the resources?

Title and Content


Design requirements

I. Requirements on the case study:

• Geometrical limitations

• Subjected to vibrations, can cause fatigue and oscillations

II. Fixed geometries & functionalities:

• Mounting points

• Oil suction pipe

• Oil-level measurement

Title and Content


Topology Optimization

III. Pre-CAD of topology optimization input in CATIA

IV. Generated concept using Altair Inspire

Title and Content


Parametric CAD model

I. Mimic topology results in a parametric CAD model.

II. Verify the manufacturability

Title and Content


Shape optimization

III. Set up simulation models to minimize the mass

1. Update parameters

2. Execute Clash Analysis

3. Execute Frequency Calculations

IV. Optimize in Heeds

Note! Only CATIA was usedfor the simulations

Title and Content


Design Verification

I. Optimal design verified with FE-experts

• Random response in Abaqus

• Gave additional learning about the component

II. No physical tests was performed

Title and Content

• The method provides the required tools to carry out optimization successfully

• Topology optimization generated more value than shape optimization

• Inspire was effective and easy to use


Result Reflection and conclusion
