Chassis simulations had to be carried out to ensure that the new chassis re-design still passes vehicle collision scenarios. The following are the results for the simulations. Since the design features only the chassis being structural, only the beam tool was used in this stress analysis of the vehicle collisions. The minimum combined stress and the maximum combined stress.
Summary of Chassis Vehicle Collision Simulations Analysis
4130 Chromoly Steel Material Properties
Property | Value |
|---|---|
Young’s Modulus (MPa) | 198 000 |
Poisson’s Ratio | 0.294 |
Bulk Modulus (MPa) | 160190 |
Shear Modulus (MPa) | 76507 |
Tensile Yield Strength (MPa) | 435 |
Compressive Yield Strength (MPa) | 435 |
Tensile Ultimate Strength (MPa) | 652 |
Compressive Ultimate Strength (MPa) | 475 |
It seems that yield strength for 4130 chromoly steel has been approximated as 460 MPa for MSXII
Maximum Combined Stress Results
...
Comments: Max strength seems to be 909 MPa, but that is at a very small point very close to the collision object. The stress might be on the collision object itself. The rest of the Chassis seems to be in a cool blue region which can go up to 300 MPa
