Maserati GranCabrio: from coupé to convertible
Usually, back a convertible is developed on an absolute platform, a ancillary aftereffect is a weight access of an boilerplate of 150 kg compared to the coupé\\saloon versions. This is due to the charge to atone for the abolishment of the aerial structural portions (roof, centre colonnade closure) with structural reinforcements positioned in the lower allotment of the under-frame and body.
With the Maserati GranCabrio this weight access has been kept to alone 100 kg acknowledgment to the optimised architecture of the under-frame and anatomy genitalia arena a structural role. This isn't alone a tinkering, but rather a fully-fledged "slimming down" treatment. The final band-aid was accomplished acknowledgment to the best avant-garde basic structural simulation techniques.
As far as the anatomy genitalia are concerned, the ambit of the aperture axle sections accept been increased, the structural allotment of the doors adapted and structural functions added to elements that usually accomplish no addition (for example, the roof stowage compartment, the aerodynamic bases and the casework receptacles).
At under-frame level, by contrast, the best cogent modifications concern:
* The complete redesign of the rear structures with the conception of a bewilderment bank positioned abaft the rear seats which has a structural function.
* The complete development of the structural genitalia of the centre colonnade and rear and advanced abutting crossmembers amid on the floor.
* The admittance in the agent alcove of the V-ROD reinforcement, two brownish rods which affix the damper domes to the under-screen crossmember appropriately advancement the durability of the body.
* The conception and apartment of altered under-body reinforcements anchored to advance the blueprint and acquiesce the accession of the ability alternation unit, advantageous accurate absorption to accumulation the functions for weight reduction.
The advanced and rear structural bases additionally blot thermo-fluid activating functions, appropriately befitting the access of Cx beneath ascendancy and carrying the air to air-conditioned bottomward the car's mechanics. The aggregate of these architecture refinements has enabled a car with such acceptable ambit as the Maserati GranCabrio, which has a 2,942 mm wheelbase, to accept outstanding activating acerbity values, with a activating torsional abundance of the anatomy in white agreement (BIW) of 27.2 Hz and a changeless torsional acerbity of 75,000 daNm\\rad. These abstracts accomplish the car actual close in structural agreement and awful acknowledging on the road, accouterment accomplished acknowledgment to the disciplinarian accumulated with a aerial akin of admiration and actually no vibrations.
As far as the alive aegis of the car's occupants is concerned, the under-frame and anatomy accept been advised to action the accomplished accessible standards, in band with the best amidst our competitors and with the coupé\\saloon versions.
When redesigning the new geometry of the aperture sills and the centre colonnade ancillary structures, as able-bodied as the rear end of the car, functions accept been incorporated, alongside the structural functions, that blot and blow the activity generated in any impact, creating a commuter alcove that charcoal around undeformed.
Particular acknowledgment should be fabricated of the actuality that an alive cycle bar arrangement has been installed to the rear of the Maserati GranCabrio body, alike admitting this is not appropriate by any legislation, as able-bodied as an avant-garde structural blended abstraction (in aluminium and steel) that reinforces the windscreen beleaguer so that the occupants are affirmed a adaptation breadth should the car overturn.
This circuitous chip development of under-frame and body, which agency that the accomplished levels of structural and assurance targets can be achieved, was fabricated accessible by a analytical development action application basic simulations and correlations amid concrete (prototypes) and basic models during the abundant analysis sessions.
