Abaqus: dynamic explcit test in a bike frame (Impact)

Abaqus: dynamic explcit test in a bike frame (Impact)

Abaqus: dynamic explcit test in a bike frame (Impact)

(OP)
Hi all!

I'm trying to make an impact of a mass to a bike frame.

To do this , I selected in "step" dynamic explicit.

Within the explicit dynamic test , I agree to the mass scaling tab - > Use scaling definitions below - > Scale to target time increment of - > 1E -006

The problem comes when I apply the load of gravity. I'm working in mm / s2 , so I enter the value -9810 .

When you begin to solve the problem, I observe how the mass acquires a lower acceleration which have put him in the box load and does not meet the equations of freefall .

I appreciate if someone could answer .

Sorry for my English and thanks!
