Mechanical Systems Design 2

TUTORIAL

Week 1

Part A - Introduction to SolidWorks Simulation

The purpose of this tutorial is for you to familiarise yourself with an introductory finite element analysis add on package to SolidWorks named Simulation.

In order to use Simulation within SolidWorks, on the top menu bar, digitise Tools > Add-Ins …>. As shown in Figure 1.0. Ticking the left-hand side box enables Simulation within SolidWorks and ticking the right hand box enables Simulation EVERY time you start up SolidWorks. This may not be desirable to you as it does add to the time for SolidWorks to start-up.

As shown in Figure 2.0, undertake the first Tutorial located in the SOLIDWORKS > Help > Tutorials > Static Analysis > Analysis of a Part. Once you have completed your first run examine in the Results tree > Stress > von Mises (a measure of the energy density as shown in Figure 3.0) to see where the maximum zones are – you may need to rotate your view accordingly.

Part B – Optimisation Examples

Once you have identified where the maximum stress and displacement are located undertake the following redesigns.

Redesign the component so that the maximum stress and displacement are minimised for the load and constraints applied. The mass of the part is not to increase, and the same material must also be used. Save your analysis for future reference. The images shown below in Figures 4.0, 4.1 and 4.2 below are for inspiration only. Use the component from Part A in order to optimise its shape using the images below for guidance. Discuss your effort with your Tutor once have completed Part B.

Part C – Manufacturing Considerations

Redesign the component with manufacturing intent i.e., what manufacturing process will be used in the manufacture of the component (not using rapid engineering methods) in a quantity of 100. Some examples of how design shapes are altered by the manufacturing process selected are included in the images described by Figures 5.0 to 8.1 below. The mass of the part is not to increase, and the same material must also be used. Save your analysis for future reference. Use the component optimised from Part B in order to optimise its shape using the images below for guidance. Discuss your effort and how it differs from Part B with your Tutor once have completed Part C.

Some suitable manufacturing processes (or combinations) are illustrated in the images below.

Part D – Shape Optimisation Through Design Study

Figure 9.0 illustrates a cantilevered bracket which has boundary conditions as shown in Figure 9.1. The aim of Part D is to undertake a shape optimisation exercise as defined in the SolidWorks Tutorial, ‘Shape Optimisation ’ as shown in Figure 9.2.

The aim of the Tutorial is to minimise the volume of the cantilevered bracket by not exceeding the maximum stress, displacement whilst ensuring that the fundamental frequency remains within a certain range. By carrying out this study, you will be exposed to parametric, feature based modelling capabilities of SolidWorks Simulation.

Once you have carried out the tutorial, alter the cantilevered bracket design into a slightly different shape of your choice and redo the shape optimisation analysis.

Part E – Topology Optimisation of a Disk Brake

Figure 10.0 illustrates a disk brake that you will use as part of a topology study. A topology study being defined as a non-parametric optimisation study which typically has an optimised goal of minimising mass. The disk brake provides a ready framework to enable the finding of an optimimal shape for the rotor part of the disk brake which has the least mass and greatest stiffness. Part E may be undertaken as part of the SolidWorks Tutorial, ‘Topology Optimisation of a Disk Brake ’ as shown in Figure 10.1.

The main aim of the Tutorial is to introduce non-parametric topological studies that result in the redesign of an existing part. By carrying out this study, you will be exposed to the creation of a topological study, applying boundary conditions, defining goals and constraints, and most importantly, being able to export the optimised result.

Once you have carried out the tutorial, alter the disk brake design into a slightly different shape of your choice and redo the topology optimisation analysis.

Part F – Design Optimisation of a Knob

Figure 11.0 illustrates a knob that you must minimise the mass of by redefining its dimensions whist using the Factor of Safety as a limiting factor as part of a topology study. Part F maybe undertaken as part of the SolidWorks Tutorial, ‘Design Optimisation of a Knob’ as shown in Figure 11.1.

The main aim of this Tutorial is to combine dimension driven design (parametric) as a methodology in the reduction of stress in order to meet a predefined criteria defined by the preset Factor of Safety.
