Parameter optimisation using Heeds MDO and DAKOTA

The objective of the work was to study the process of the parameter optimisation applied to a multibody simulation model and to run two optimisation cases using two optimisation software applications: HEEDS MDO 7.1 and DAKOTA version 5.3.1.The industrial case studies were performed using a simulation model of an elevator. The selected vibration feature was optimised using different design variables of the system. The feature was evaluated using a scalar valued objective function and also inequality constraints for the optimisation were defined. Both optimisation case studies were successful. Both case studies were run with the default parameter values of the optimisation methods. Tools for the parameter optimisation and especially the mathematical algorithms inside them were found capable and robust for parameter optimisation of multibody models.
