The objective of this research is to determine positions and weights of relocatable equipments in amphibious vehicles, to maximize payload of the vehicles without losing vehicle controlability in water. System equations analyze static state of vehicles in water is devised and solved numerically.
Then an optimization problem is formulated by choosing the total weight of equipments as cost function, locations and weights of the equipments as design variables, the system equations as state equations, and various necessary conditions required for normal operation of the vehicles in water as design constraints.
After the design sensitivity analysis is performed, the system is optimized with the linearization optimization algorithm. A program based on the theory is developed and tested with example problems.
Research results fully demonstrate that the suggested procedure is stable and can be widely applied to the practical military vehicle design.
