Material Law Identification

PAM-OPT helps to determine the five parameters of the plasticity and strain rate law of a steel column to match an experimental impact test simulated with PAM-CRASH 2G. The optimization process consists of two steps: identifying the hardening and identifying the strain rate law.

Safety Restraint System Optimization

PAM-OPT helps identify values for the restraint system parameters that minimize a combination of injury functions. The Articulated Rigid Body dummy model is restrained by seatbelts, airbag, knee bolsters and a deformable steering column. Based on a PAM-SAFE model of a sled test, PAM-OPT minimizes the Head Injury Coefficient (HIC) response, the 3 milliseconds chest and pelvis accelerations, and the left and right femur loads.

Structural Crash Design Optimization

Tuning 31 design parameters, PAM-OPT helped Isuzu engineers achieve a 60kg weight reduction for the design of an original truck frame design. Isuzu engineers found a more efficient collapse mode, while respecting the intrusion constraint.

Manufacturing Process Optimization

PAM-OPT allows you to tune any kind of manufacturing process such as sheet metal forming.
Using PAM-STAMP 2G for stamping simulation, PAM-OPT helps users find the best process parameters to avoid tear problems. PAM-OPT optimizes the combination of drawbead forces, material grades, friction coefficients, and cutting pattern.
