主　　题：Machine vibrations 

摘      要：An approximate solution of the problem of linear-quadratic optimal control of the ground-induced vibrations of a vehicle travelling with variable velocity is presented. A new model in the form of a retarded functional differential equation is established which represents both vehicle dynamics and surface properties. By formulating the model in the spatial domain a number of technical difficulties are removed, and it is seen how constant spatial delays can be accommodated by using rational approximations. Equivalence between the space- and time-domain formulations is established, and an example demonstrating the viability of the approach is discussed.
