MECE


Problem statement
Problem Statement

  • The Mini Baja Frame needs to withstand any collision that it might be subjected to as part of the testing process or competition.

  • Four impact scenarios were analyzed to ensure the frame design will not fail.

    • Front Impact

    • Rear Impact

    • Side Impact

    • Roll Over


Material properties
Material Properties

  • The frame material is 4130 N Chromoly Steel with an outer diameter of 1.125” and wall thickness of 0.058” but was modeled as solid rods with1.125” diameter.

  • Elastic Modulus 29 * 10^6 psi

  • Poisson’s Ratio .25

  • Yield Stress 1.16 * 10^5 psi





Forces and constraints
Forces and Constraints

  • The force of 7111 lbf was divided by four and applied to the four front most points of the car (1777.75 lbf).

  • The rear most points of the car was constrained to prevent movement.





Forces and constraints1
Forces and Constraints

  • The force of 9026 lbf was divided by four and applied to the four rear most points of the car (2256.5 lbf).

  • The front most points of the car was constrained to prevent movement.






Forces and constraints2
Forces and Constraints

  • The force of 9026 lbf was divided by four and applied to the right most points of the car (2256.5 lbf).

  • The left most points of the car was constrained to prevent movement.





Forces and constraints3
Forces and Constraints

  • The force of 7111 lbf was divided by two and applied to the top most points of the car (3555.50 lbf).

  • The bottom of the car was constrained to prevent movement.







Conclusions
Conclusions

  • The solid model can only be used to determine places where there is a stress concentration.

  • The proposed alternative reduces the stress concentration at desired location.
