The part (1) of the composite structural member is at least partially connected via connections (3,5) to one or more further parts (2,4) comprising of a mainly thin-walled plate-like material. Accordingly, a structure suitable for loading and weight is produced using the light metal composite structural member in a preferable method. One embodiment is back box lid of motor vehicles.
Description
Special in the production of vehicle body, allow the plurality of material properties in a member to use more and morely according to running operating mode and accurate harmonious material and the combination of materials of mounting condition.Up to the present, the member of being made by sheet metal or thin-walled section spare is used in this respect, for example, mainly produces vehicle body by the thermal bonding method from a large amount of single-pieces with these members.
In car construction, utilize the material of forming by light metal material or light-metal alloy more and more, with vehicle body crust or other load-carrying element of these manufacture of materials power actuated vehicles, up to producing the vehicle body that constitutes by light metal fully.These light metals mainly are aluminium, also use magnesium now more and more, and the two is all welcome especially aspect the practicality of its process technology angle and distinctive material value.
If these light metal materials are used in the car construction, debatable especially is that the strength characteristics of light metal plate is not enough to the load that some vehicle part bore.More debatable and the light metal plate that is to use that attempted replaces vehicle body large tracts of land steel part--for example crust--replaces with aluminum component, because they do not bear extra high load usually.Yet, particularly bearing under the situation of high mechanical load at member, single load and load group can appear, and make and can not produce these functors with the light metal plate of suitable shape.Perhaps member damages prematurely owing to too high single load, permanent failure perhaps occurs all far away early than the situation of steel part owing to fracture by fatigue.
A possibility that improves the light metal component strength is, production for the light metal member, be not to use thin light metal plate, and the foundry goods that is to use light metal or light-metal alloy to make, possibility according to foundry engieering, these foundry goods can provide more material in higher load zones, thereby can a kind of more suitably mode be that specific load designs.Yet, minimum wall thickness (MINI W.) according to the casting this casting light metal spare that requires, these parts are not bearing top load like this district also than only many with the light metal spare recuperation of thin light metal plate production, and the weight that the result is to use light metal material to bring reduces major part and lost again.
