Week 3- Geometry cleanup and Mid-surfacing

CASE 1

AIM : To extract the mid surface for the tube model. And provide a connection.

PROCEDURE:

STEP 1: OPEN THE DESIGN MODELER.

STEP 2: IMPORT THE MODEL.

file > import external geometry file

STEP 3: SET THE UNIT IN millimeter

STEP 4: EXTRACTION OF MID SURFACE.

First hide all other bodies and set visible only one body like this,

Then go to, tools > mid surface

Then press, GENERATE button.

Do same operation for all bodies.

STEP 5: EXTENDING THE SURFACES.

tools > surface extension

Do the same operation for all other joining positions.

CASE 2

AIM: Create a model in SpaceClaim one on top of each other and create a shared topology between top box and bottom box. And perform a modal analysis(free-free run) verify connections and analys the result.

PROCEDURE:

STEP 1: OPEN MODAL ANALYSIS.

Choose modal analysis.

STEP 2: SETTING ENGINEERING DATA

Here I am using default material, that is structural steel.

STEP 3: OPEN SPACE CLAIM(GEOMETRY)

Here we can create model.

First make a rectangle dimension of 40x40 mm

After making rectangle by using PULL option we can make thickness of 10mm.

Then we have to make a link between top and bottom box.

Then use pull option

Then make top box dimension of 20x20x5mm

The model is ready, then we can move to mechanical.

STEP 4: OPEN MODEL (MECHANICAL)

After opening the mechanical, we should check geometry(property) and material.

STEP 5: MESHING

Our Element order should be linear.

1. Insert method

This is a solid model, so we can use Hex dominant method.

2. insert sizzing

Here we can use 2mm element size.

Then generate mesh

STEP 6: APPLY BOUNDARY CONDITION

Here we should fix the bottom surface of block B.

modal > insert > fixed support

STEP 7: CHANGE NO:OF MODES

Go to Analysis settings give 10 to Max Modes to Find,

STEP 8: ADD TOTAL DEFORMATION

solution > insert > deformation > total

STEP 9: SOLVE THE PROBLEM.

solution > solve

There we given as 10 modes, So here we can see that 10 modes with natural freequency.

Here we can see participation factor on rotation Z direction.
