Abstract:
This study attempts to optimise the dynamic performance of a fixed tank two-axle vehicle, with respect to the lateral performance of the installed tank. For the description of the fixed-tank-vehicle, a linear full-car model with ten degrees of freedom (DOF) is implemented, subject to many types of road irregularities. The corresponding stiffness and damping characteristics of tank’s supports are optimised simultaneously with the relative characteristics of vehicle’s suspension, such that the maximum value of the tank’s vertical acceleration, taking under consideration all the design limitations, as well as the geometrical constraints of the vehicle. For the optimisation procedure, the BFGS quasi-Newton, the Complex and the (μ+λ)-Evolution Strategy methods are implemented.
