With U·Sim (Usage Simulation), customer usage simulations can be performed to extrapolate data to the entire life of the vehicle. Customers are generated according to usage profiles using Monte Carlo simulation and are represented by real measurement data. The quantile customers define a design target in combination with safety factors and special maneuvers (e.g. kerbstone crossings).
Based on a reference load, U·SimOpt (Usage Simulation-Optimization) is used to determine optimal track combinations to derive test scenarios. For this purpose, the reference load is mapped to the test track measurements by means of optimization. Restrictions due to the structure of the proving ground can be taken into account. A compressed description of the loads can be determined for simulations with MBS and FEM.
