Vehicle Structures

Download this app named Vehicle Structures.

The application can be used for any arbitrary indefinite structure to calculate the load factors (delta), the vector x and its whole stress figure from its bending stress or normal stress figures.
You can draw a structure a the Draw structure pane by clicking the line icon.
Every rod must be attached to one end of another rod.
If the desired structure consists of a rod starting from the middle of another rod, you can solve this problem by splitting the latter into two.
By clicking the hand icon we can click on each rod and specify its length (l) and stiffness (AE/IE) property.
These parameters must be defined within every rod for a proper structure.
The longitudinal and bending stiffnesses cannot be mixed, the same kind has to be applied for each rod in the structure.
For a normal stress figure use the AE property, and IE for bending stress.
Thereafter we can draw the single stress figures.
By clicking on the rods, we can specify their load on both ends (the start end is designated with an S, the other with an E).
The load figure can only be linear; the positive direction is left from the vector pointing from the rod start to the end by default.
Having submitted the desired stress figures, by clicking the calculate button, we get the stress diagram of the whole indefinite structure, along with the detailed presentment of the load factors and the vector x.
From here, we can give the unit load diagrams to calculate dislocations of a point in the structure.
