Week 9-Creation of 1D Connectors Challenge

AIM : CREATION OF 1D CONNECTORS

PROCEDURE :

> The given component model import

>Then given the assembly part,we going to creation of 1D connectors in different various connectors

>Relizing the connectors

STEP 1 :

>Firstly Given midsurface of all assembly parts ,generated 2D mesh

>Check the quality parameters of given values

>Then Exact the mid surface of assembly part

>After mid surface, go with automesh (f12) and mesh the component

>See the quality criteria values while doing the mesh

>Then Creation of 1D Connectors in different connectors

>Lets the creating different components,were as given of various components names are

> CREATING THE SEAM CONNECTOR:

>SEAM CONNECTOR :

The process of joining the workpieces which is made of similar or dissimilar material along a continuous seam is known as seam weld

>Seam weld in hypermesh :

>Firstly taken the given component to weld of component

>While completing doing the mesh, the given required component is taken Right rail 2 and front truss

>Then go with 1D connectors,- connector-seam

>Select seam -spacing- tolerance- type - create

>Then created the seam-quad(angled+capped+L)

>The component of right rail 1 and front truss 1

(a) The components while after creating seam weld (b) Here the clearly of seam weld component by two comopment

>Second part of component quad weld :

>Left rail 2 and front truss 1

>

(a) The component of a while before creating the quad weld (b)clearly weld of quad weld

>THIRD PART SPOT WELD

>component front truss 2 and front 1 and right rail 1

>spot weld with 3 layers and 5 mm diameter

(a) Before creating the spot weld (b) After creating the spot weld bush type weld

>FOURTH CREATING THE HERA(ADHESIVE):

(a)Before creating the Hexa connector (b) created Hexa (adhesive) connector weld

FIFTH CREATING OF BOLT CONNECTOR

>

>we created a bolt weld connector

>select a node at a center of component

>select a component by two component

>Then click the create option

SIX CREATING A BOLT CONNECTOR

SEVENTH SPOT_WELD_WITH_RIGID ELEMENT

>

(a) Before the spot weld with rigid (b)After creating a spot weld with rigid element

EIGHT SPOT WELD WELD WITH SPRING ELEMENT

(a) Before the spot weld with spring element (b)After creating the spot weld with spring element

IMPORTANTANCE :

• CONNECTORS:

> Connectorsallow you to create relationship between two nodes in a FEA model when we discretize a complex CAD model

>The connections can be simple by using rigid or some of them will be weld or bolt connection ,which can impose the more complicated constraints

Here i using from example of connector with spring component face 1 and face 2

• CONNECTION BASICS :

>IN A FE - Model connection are basically used to join or assemble two or more parts together

>It can be mesh dependent or mesh independent

>Either contact or contactless

• MAJOR PROPERTIES OF THE CONNECTORS :

>Connector stiffness

>Force experienced by the connector

>Type of failure or mode of failure experience by the connector

• TYPES OF CONNECTORS PREFERRED

>1D Connectors :

>Simple representation and fast calculation

>Connection stiffness may not be an issue forcalculation

>2D connectors :

>Connection stiffness has to be considered

>accurate modelling of physical seenario

>To capture the connector deformation in modelling

>Mostly are welds , seam welds and bolt outer layer

• FINITE ELEMENT ENTITIES CONNECTORS REPRESENTATION :

>1D ----Rigid , bars,beams,spring etc.

>2D----Weld shell elements, bolts outerlayer elements etc

>3D----Solid bolt and nut representation ,are spot weld hexa

• STATES IN CONNECTORS RELIZATION :

>There are some representation of during connectors

>YELLOW COLOUR -----"Unrealized connector"

>GREEN COLOUR ------"Realized successful creation"

>RED COLOUR -------"Which are failed to the connectors"

• BOLTS :

>A Bolt connection models a device that connects two compononebts,multiple components,or a component and the ground . it fixes these parts together

HERE i was using the example of a pipe route contain has many bolted fanges

• SPOT WELD :

>Spot welds can be used to join two very thin pieces of metal , they function best when the parts are less than 3mm thickness

Spot weld in blue colour join the roof sides of a model a car

• REALIZING CONNECTORS can be done in a way :

• IF ANY FAILURE OF WHILE DOING THE 1D CONNECTORS >Once check free edges ,and find out clear it by the equivalance option >And once check the duplicated elements

• VEIW THE CONNECTOR IN HYPERMESH THEN SEE DIFFERENCE OF FAILED AND RELIZED :

• TOLERENCE : The gap of difference between min size and maximum size

>CAP ANGLE : Angle between the normal of the first slant weld element and in adjacent side element

>WELD ANGLE : Angle between the normal projection of the nodes and slant length of the weld element it is recommended to define weld angle between 0 and 90 degree

>RUNOFF ANGLE : Angle between the normal of the first slant weld element and its weld adjacent weld element

FINALLY CONNECTORS WITH ASSEMBLY PART :

UNDESTAND BY THIS TOPIC

>How to created of 1D connectors, seam,bolt, Hexa,spring ,etc

>How to Realizing and non-realizing error

>What is the Weld Eagle,runoff angle,cap angle differences

CONCLUSION :

>Finally created the 1D connectors of different components and different welds
