While the form of resistance represents a decisive value for the stress of the material, the moment of inertia is important mainly
for the flexural hardness and for the quota of the bending moment to be taken, depending on the connection used.
Aluminium counter chassis
When using materials with different characteristics from those of steel (e.g. aluminium), the size and structure of the counter
chassis must be appropriately adjusted.
1. When the contribution of the counter chassis is mainly that of providing a uniform distribution of load and the chassis has
the fundamental task of resistance, aluminium longitudinal profiles having dimensions similar to those indicated for the steel
can be used. Typical examples are fixed bodies, vans and tanks, provided that the supports are continuous and close-up or
in the immediate vicinity of the suspension mounts. An exception is made in cases where high stresses on the chassis require
relatively large sections of the steel reinforcement, cut-resistant links.
2. When the counter chassis is prompted to make a contribution in terms of strength and hardness (e.g. superstructures with
high concentrated loads, tipping bodies, cranes, centre axle trailers, etc..), the use of aluminium is generally not recommended
and should be authorised from time to time by IVECO.
