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 subframe
When using materials with different characteristics from those of steel (e.g. aluminium), the size and structure of the subframe
must be appropriately adjusted.
1. When the contribution of the subframe is mainly that of providing a uniform distribution of load and the chassis has the funda-
mental 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 immedi-
ate 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 subframe 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.
Please note that in defining the minimum size of the reinforcement profiles in addition to the limit of the allowable stress for
aluminium, reference must be made to the different Elastic Modulus with respect to steel (approx. 7,000 kg/mm
2
against 21,000
kg/mm
2
for steel) which involves greater dimensioning of the profiles.
