Assignment 7-Side Pole Crash Simulation Challenge

Objective:

Procedure:

• Create Type 7 interface, with friction 0.2, and recommended parameters.
• Make sure of no penetration and intersections by using tool>penetration check.
• Create a rigid wall with friction 0.1. Enter geometry type as Cylinder.
• Create Initial velocity - 20mph=8.9408 m/s.
• Use Tools>Model checker>RadiossBlock to ensure good quality.
• Edit ENG_DT_NODA Tmin value as 0.001.
• Edit ENG_RUN card by setting T stop as 80ms.

Output requests:

Intrusion at B pillar,hinge pillar and fuel tank region:

Since Imposed Displacement is 734 mm the intrusion happening at

• Fuel Tank region: 0.71 mm
• B pillar region: 417.015 mm
• Hinge Pillar region: 30.822 mm

Peak velocity of an inner node of the door:Node Id 337773 = 8.94 m/s.

Here acceleration graph cannot be considered to calculate peak velocity. The acceleration graph needs to converted to square wave form graph to get the area under curve as velocity. But instead you can use Displacement vs Time graph and use max value of slope to calculate Peak velocity reached by that node.
