Week - 4 - Crash Box Simulation

For crash box analysis we followed gm-mm-ms unit system

Results:

1. Crash box with thickness 1.2mm

cross-sectional force at middle, Acceleration at middle, sliding energy and all energy curve graph for CB with 1.2mm thickness is below,

maximum x stress and effective plastic strain,

2. Crash box with 1.5mm thickness

cross-sectional force at middle, Acceleration at middle, sliding energy and all energy curve graph for CB with 1.5mm thickness is below,

maximum x stress and effective plastic strain,

3. comparision:

from the graph it shows that maximum stress and maximum strain developed in crash box with 1.2mm thickness and minimum in crash box with 1.5mm thikness.

from the graph it shows that maximum acceleration experienced in CB_1.2mm than CB_1.5mm.
