Known according to above-mentioned content, this truss can form a kind of structural type of topology, and this truss topological structure can make the static bearing capacity of integral body of truss more intense on the one hand, dynamic (dynamical) characteristic is improved preferably, on the other hand can also be in the situation that guarantee that structure has identical mechanical characteristic, the layout of this truss structure can make truss have lighter quality, and then can avoid the waste of material, cost-saving.
It should be added that; usually cabin truss topology design has following several step: determine design object, understand design space, load and boundary conditions; draft the preliminary structure design proposal according to these known quantities; and complete Static Calculation and modal analysis in finite element; by result of calculation, structure is improved; the modification design proposal that iterates, find out optimal solution.
Wherein, for the arrangement of truss:
Can use topological optimization technology, find the conceptual design of truss structure, the load that this process is born in conjunction with the device layout in cabin, truss and the position that loads and retrain, define boundary conditions by finite element software and carry out topological optimization, the result of optimizing will demonstrate the reasonable layout of material, and the arrangement of truss, instruct the design of structure, whole strain energy is reduced, and it is the lightest that oeverall quality reaches.
The topological optimization of truss has certain directive significance for the layout of truss, but the result of FEM (finite element) calculation and actual design structure have different, need be according to the result of optimizing, feasibility in conjunction with processing technology, make the preliminary arrangement of truss, therefore under this mentality of designing, a kind of truss structure that the utility model provides has been proposed.
For the cross section type selecting of truss:
The truss structure part that is arranged on diverse location is divided into groups, wherein, the structural member of one group that plays same function will have identical section selection, therefore can the beam in this truss be divided into to four groups according to same-action not, particularly, the purlin car upper beam 1 (slide rail) of bearing unbending can be divided into to one group, bottom end rail 2 is divided into one group, play and support and the attaching beam of load-bearing effect (i.e. the first support beam 4, the second support beam 5, the 3rd support beam 6, the 4th support beam 7, the 5th support beam 8) be divided into one group, pull beam (the i.e. first oblique pull beam 9 of engineroom flat effect, the second oblique pull beam 10, the 3rd oblique pull beam 11, the 4th oblique pull beam 12) be divided into one group.
The cross section of all beams can be inquired about according to mechanical design handbook, thereby can set up the database of cross section type selecting, the total three types in general optional standby cross section: I-steel, rectangle clod wash Hollow Steel, square clod wash Hollow Steel.Target is given rational cross section the truss of different grouping, can make the static(al) of truss structure, dynamic performance better.
In conjunction with foregoing, the optional scheme of conduct in the utility model embodiment, the cross section of above-mentioned four groups of beams is square clod wash Hollow Steel as shown in Figure 2, be that described upper beam 1, described bottom end rail 2, described the first support beam 4 to the 5th support beam 8, described the first oblique pull beam 9 to described the 4th oblique pull beam 12 are square clod wash Hollow Steel, can make like this truss there is better static bearing capacity and dynamics
.
