As shown in Fig. 2 embodiments providing a kind of method determining support, the method can include following walking
Suddenly：
Step 201：Set up the threedimensional model of support.
In embodiments of the present invention, this support can be air conditioner support.
This threedimensional model can be set up by UG.The threedimensional model of foundation can be loaded into UGNASTRAN module
Emulated.Threedimensional model is finite element analyses and the basis calculating, therefore, the conjunction that built by UG in UG NASTRAN
Reason, parameterized threedimensional model, can greatly improve emulation and optimize the speed calculating and efficiency.
Can be according to the size of support, the profile of support, each minor structure of support in the threedimensional model setting up support

In carry out stress and strain model.Separate in grid division between minor structure, it is independent of each other.
When carrying out stress and strain model, the different demarcation for the material of zoning goes out different grids, or, according to calculating area
The size in domain divides different grids, for example：The area of zoning is more than or equal to the first preset value, the then area of each grid
More than or equal to the second preset value, the grid of this zoning is relatively sparse；The area of zoning is less than the first preset value, then often
The area of individual grid is less than the second preset value, grid comparatively dense.
Step 206：Determine the deformation constraints of threedimensional model.

Connected mode between minor structure may affect the active force that support can bear, for example：If minor structure
Between connected mode be bonding or weld, the active force that the connected mode of bonding can bear may just can bear than welding
Active force little, and then emulation when, different connected modes may obtain different simulation results.
Step 208：Determine the size and Orientation of stress in the presence of target to be supported for the threedimensional model.
Here stress refers to the active force that support may bear when actually used.Can be simulated by this step and prop up
The actual loading situation of frame is so that simulation result is more accurate.
Step 209：According to the net in the material of threedimensional model, physical attribute, structural constraint and load, and zoning
Lattice, emulate to the zoning of threedimensional model, generate simulation result.
Before this step, can also include：Whether detection threedimensional model has unreasonable part, if there are then to unreasonable
Part is modified, and after threedimensional model no problem is detected, then is emulated.
Can determine that whether this support can sustain target to be supported by emulation.Specifically, can pre-set
The stress tolerance range of each minor structure of support, or strain tolerance range, if beyond this stress tolerance range or strain
Tolerance range then determines that this support can not sustain target to be supported, and this support is unsatisfactory for requiring.
Here simulation result can include the stressing conditions of support, strained situation, the material of this support.Physical attribute
Deng.
Step 210：Determine whether support meets requirement according to simulation result.
Can get stress, the strained situation of support according to simulation result, determine whether to meet demand according to simulation result,
If it is, determine that support meets requiring, Output simulation is reported, can produce support according to the parameter in simulation report；If not,
Then return the threedimensional model to support to be redesigned and adjust, re-start emulation, until being met the support of requirement.
In embodiments of the present invention, it is possible to use the powerful modeling function of UG pre-treatment sets up the threedimensional model of support, profit
Threedimensional model is emulated so that modeling and simulation forms seamless company with advantage in terms of finite element analyses for the UG NASTRAN
Connect, the integrated analysis such as the design of formation support, simulation, optimization, improve designing quality, improve simulation efficiency, shorten trial-production all
Phase, reduce production cost, improve market competition ability.
