Abstract
Two design pallet models, namely, a model of piecewise-constant thickness and a model of
constant thickness within preset geometrical external dimensions are discussed. When optimizing
pallets,
two ways of changing the design variables were studied:
a
) constant thickness for a single
finite element,
b
) constant thickness for a group of finite elements: Group 1 includes plate finite
elements (FE) in the xz and yz planes, group 2 covers plate FEs in the xy plane, group 3 includes
rod FEs.
It is shown that both pallet models are almost identical in weight. The model of constant
thickness within preset geometrical external sizes is recommended for practical application.
