Partitional modeling and conode-connecting method was applied during modeling process and as a result, the stress of the bracket was over concentrated and failed to meet the requirements of impact resistance. So it suggests that the bracket should be produced through casting method and widen the flange on the bracket as well as increase the rib and fillet for reducing stress concentration around the bracket thus to connect the load-carrying parts on both sides of the bracket into a whole body. The load-carrying condition of vibration isolator has met the requirements of national military standard, while it is not possible to check and test its deformation performance for the lack of reference standard.

The reason is that the bracket taken in the modeling block modeling of node connection method, the stress concentration , and can not meet the impact requirements . Recommended bracket to take casting production, to increase the flange width of the bracket , ribs , rounded to reduce stress concentration , making parts of the connection as a whole of force around the bay . Isolator force conditions to meet the standard requirements of the national army , but the deformation due to non- reference standard check .
It can not meet the requirements of impact resistance because of the strong stress concentration. It is acceptable to cast the bracket, but not to model partly and then join it together. It is of great advantage to widen the flange(法兰)and increase the sprag and fillet,and so to connect the bracket into a whole body to reduce the stress concentration effectively. Therefore, the vibration would meet the GJB requirements. However, it is not available to make sure the deformation change because the lack of the reference standard.
