Detailed description of the invention
Below in conjunction with schematic diagram, the present invention is specifically illustrated.
Design the initial stage at battery case, according to the load that battery case is suffered in running car, model is applied perimeter strip
Part and load, inertia force direction suffered by battery case is as it is shown in figure 1, wherein 1 represent head-on crash process battery case and be hit load
Lotus, 2 represent the battery shock loading to battery case front apron when bringing to a halt, and during 3 representative zig zag, battery is to battery case side shield
Shock loading, 4 represent the battery shock loading to tank floor, 5 battery case impact load when representing side collision.
It is as shown in table 1 that battery case G-Load analyzes load working condition.
Table 1G-Load analyzes load working condition
The laying angle of battery case carbon fibre composite is 0 °, ± 45 °, 90 °.
Under above-mentioned load working condition, after Optistruct free size optimizes, 0 ° of carbon fiber overlay thickness is distributed such as
Shown in Fig. 2；± 45 ° of carbon fiber overlay thickness are distributed as shown in Figure 3；90 ° of carbon fiber overlay thickness are distributed as shown in Figure 4.
Under above-mentioned load working condition, after Optistruct is dimensionally-optimised and stacking sequence optimizes, battery case final
Ply stacking-sequence is as shown in table 2, and battery case final thickness is distributed as shown in Figure 5.
The final ply stacking-sequence of table 2 battery case
Being bonded as one by binding agent between each layer of battery case, binding agent selects thermosetting resin, i.e. unsaturated polyester (UP) tree
Fat or epoxy resin.
It is bolted between casing and the hanger of this battery case.
The above is only the better embodiment of the application, is not embodied as scope with what this limited the present invention, should
When pointing out for those skilled in the art, on the premise of without departing from principle, it is also possible to make some changing
Entering and retouch, these improvements and modifications also should be regarded as the protection domain of the application.
