Assignment 7-Side Pole Crash Simulation Challenge

REPORT

AIM:

Neon side crash -BIW

• Check unit system and either follow [Mg mm s] or [Kg mm ms].
• Create an appropriate interface, friction 0.2, and recommended parameters.
• Make sure of no penetration and intersections.
• Create a rigid wall with friction 0.1 as per the reference model.
• Compare the model weight with the reference model and use added masses to reach the target weight of 700kg while getting CG about the required range.
• Initial velocity - 20mph, as per the standards.
• Use model checker to ensure good quality.
• Timestep :0.5 to 0.1 microseconds.
• Run 80ms.

Output requests:

• Sectional force in the cross member.
• Intrusion at B pillar,hinge pillar and fuel tank region. Provide recommendations on what can help to reduce Fuel tank intrusion.
• Peak velocity of an inner node of the door.

Note:

1. Submit your simulation files including time and h3d files.
2. Plot energies and notice any difference.

3. Explain your errors and how to rectify them?

PROCEDURE:

1IMPORT THE GEOMETRY IN RADIOSS -HYPERMESH.

2.CHECK FOR THE UNITS.SOLVER>BEGIN>

3.OR IN THE NOTEPAD BY GOING TO THE RAD FILE 1.

4.GO TO HYPERCRASH-PREFERENCE (AT THE RIGHT TOP)>HYPERCRASH.

5.DRAG THE RAD FILE IN TH HYPERCRASH.

6.CHECK FOR CONTACT BETWEEN THE ELEMENTS.

7.CHECK FOR MASS.

8.IN THE HYPERMESH GIVE THE MASS BY GOING TO THE ADMASS OPTION AND SELECTING THE NODES AT THE BOTTOM AND ASSIGNING MASS TO EACH NODE IN THE OPTION .

9.CREATE INTER AND ASSIGN THE TYPE 7 CONTACR IN THE CARD IMAGE AND GIVE THE NECESSARY INPUT TO THE CONATACT.

10.CREATE THE RWALL-CREATE>RWALL>CYC.

10.CREATE FRAME>SELECT NODES>X-AXIS TO BOTH THE B.PILLAR AND THE SEAT SUPPORT.

11.CREATE SECTION>SELECT THE FRAME> ANSD ASSIGN THE NODES ACCORDING TO THE FRAME NODES.

13.CREATE TH FILE FOR EACH COMPONENTS.

14.CREATE THE PROPERTY CARD AND THE COMPONENT CARD FOR THE SPRINGS.GIVE THE MASS AND THE SPRING CONSTANT.

15.CREATE SKEW FOR THE SIDE DOOR .CREATE>SKEW>MOV.SELCT THE NODES

SEE THAT THAT THE OUTPUT BLOCK HAS BEEN CREATED IN THE MODEL BROWSER FOR ALL THE ASSIGNED COMPONENTS>ASSIGN THE OUTPUT BLOCKS PROPERLY.

GIVE THE TIME AND THE VELOCITY.

OUTPUT:

1.CHECK THE MODEL FOR ANY ERRORS.IF NO ERROR ARE THERE THEN RUN THE MODEL BY USING THE RADIOSS BROWSER AND SAVE THE MODEL IN THE FOLDER.

2.AFTER THE H3N FILE IS CREATES CHECKK THE CRASH AND USE THE HYPER GRAPH FOR THE VARIATION CREATED IN THE DDIFFERENT COMPONENTS.

CONCLUSION : IN THE GRAPH THE VARIATION IN THE DEFORMATION CREATED IN VARIOUS COMPONENTS ARE STUDIED VERY PROPERLY YOU CAN DIFFERENTIATE PROPERLY THE FORCES APPLIES IN VARIOUS SECTORS.
