MORPHING TECHNIQUES BY USING ANSA

MORPHING TECHNIQUES BY USING ANSA

AIM : To perform basic morphing technique for the given CAD model

THEORY : Morphing is a design change terminology or morphing is use to change the design or shape of any component with or without any numerical input's.

EXAMPLE : Honda Brio (Hatch batch version) and Honda AMAZE (Sedan version of Brio) .

PROCEDURE :

STEP 1 : GEOMETRY CLEAN UP

STEP 2 : MORPHING

CONCLUSION

In this model we get to know about how a model will be look like when design is change

It's required lot of time effort etc..

Morphing can be done in many ways but here we are using only FREE - FREE morphing method its a basic step of morphing

Here we just morph the given CAD model at any direction we want so that it giving a new shape and new size

So to do that iam importing my given cad model and clean up the geometry then iam going to try out basic morphing techniques in this component

STEP 1 : GEOMETRY CLEAN UP

Import the given CAD model into ANSA

FILE >> OPEN >> CAD MODEL

IMPORTING CAD MODEL

MODEL IS IMPORTED

Now check the model for geometry check on top of commands select geometry check. this displayed some errors of triple cons

GEOMTERY CHECK

ERROS

Here we need to fix those errors by using contrl A then right click and fix

Still we have some errors of triple cons here we need to fix those errors by manual method by using cons release under topo

TOPO MODE >> CONS >> RELEASE

RELEASE OF TRIPLE CON

APPLYING TOPO

ERROS ARE FIXED

Now the erroe are fixed we can proceed for morph techniques

Before move to morphing mode first set the proper orientation and change the perimeter length to 1mm

MESH MODE >> PERIMETER >> LENGTH >> 1mm

STEP 2 : Morphing

First delete all bolts and nuts

select the face where to morph then goto morph mode

Here we can see boxes under morph module buttons

Select new

Under new the sub option called ortho then select geometry select the face by box selection

MORPH MODE >> BOXES >> NEW >> ORTHO >> GEOMETRY

CAD MODEL

NEW MORPH BY GEOMETRY SELECTION

MORPH BOX CREATED

Now i have created a morphing box

This morphing box have control grid so this box move along the control grid only

Control grid can be moved by numerically or by our panel input this based on the global co-ordinate

If you want a loacal co -ordinate can also be made by right clicking in mouse anywhere inside the morph window

Now i want to increase the size of the CAD by specific measurement

Here the intial measurement of CAD is 10mm and plate thickness is 2mm

So now total height of CAD is 12mm

Now change the size of CAD

MORPH MODE >> BOX MORPHING >> MOVE >> SELECT NODES or ENTITIES

SELECTION OF NODE

Now i will Reshape my morph by selecting node to move along the Y-direction

Now you can see the size of CAD is increased this will give an idea of how it will look like when its increased

RESHAPE THE SELECTING PART

Morphing might give some distrubance on the CAD model but it will definitely tell you how the component would look like when it has to be morph

Now again i will select new by box selection >> ortho create box and move along nodes that has to be selected

CREATED A MORPH BOX

RESHAPE THE SELECTED PART

Now again select different face to morph by using morph box here we are selecting full CAD component as a box selecion in which we can project hot points of CAD model to the morph box so it will form a split boxes as shown below

SPLIT BOX WILL CREATE

RESHAPE OF SOME MORE COMPONENTS IN THE MODEL

OFFSET :

For offset we need to select the CAD part that have to offset

Select by box selection >> new >> geometry >> set the part >> middle click

SELECT PART TO OFFSET

Now create a morph box

MORPH BOX CREATED

Now goto offset under box morphing give a value and slide the needle as shown in below fig

OFFSET PARAMETRIC MOVEMENT TAB

FINAL OFFSET PART

Now select any one identical face in CAD model

Create a morph box to the selected face and move the face

Then reshape that part as shown in fig below

MORPH BOX CREATED

REMESH OF SELECTED IDENTICAL PART

This is easy and simple method

This is one of the method that combination of simple and complex morphing method where introduce to make those design changes for a given model

For this required a lot of knowledge and idea to work on the model

This give an engineer to freedom to change the design upto the extend that he want to be change

In morphing any type of change of shape can be done

ADVANTAGE OF MORPHING :

It can be worl on both CAD and FE model.

DISADVANTAGE OF MORPHING :

It will give some disturbance to the given model.

RESULT : Morphing techniques done for a given CAD model

FINAL MORPH MODEL

LEARNING OUTCOMES :

1. Learned how to do basic of morphing techniques .
2. Learned how to create a morph box .
3. Learned how to move morph box by selecting entities or nodes .
4. Learned how to change the design of given CAD model .
