Abstract
The optimization problem of the ride characteristics of a travelling truck is considered. Its dynamic behaviour is approximated by linear FE models (both 2-D and 3-D). The road surface profile is presented as a random function with known power spectral density. The design variables comprise geometry as well as spring and damper properties. Limitations are imposed on maximum values of the relative displacements of suspensions, dynamic wheel load to axles, acceleration of the cargo.
The above problem is solved using a multipoint approximation method. To reduce the computational cost a two-level optimization procedure for the truck optimization problem is proposed.
It is demonstrated that the method used is efficient for optimizing the dynamic behaviour of complex structures and it is also promising for geometrically non-linear dynamic problems. Moreover it can easily be coupled with a general-purpose finite-element software package.
