There are already many companies try to launch the new motor type, axial-change power set ,the only difference in appearance of different power motors is in axial length, and the other section, like radial length, and all locking points remain the same size, Therefore, if you need to exchange a different output power motor, the body structure which needs to be changed can be significantly reduced, we got the idea of design extended electric vehicle power brace. At design stage, using the ANSYS to assess the strength and rigidity - After passing the verifying - output the design prototype by CNC processing and equip it with real vehicle. Preliminary results from the simulation, define the power system can withstand the maximum load, the load of X direction and Y direction should not exceed ± 4G, the load of Z direction should not exceed ± 3G, in order to avoid the bracket failure situation. But in actual electric vehicles operation, the power system will not only withstand the load in one direction, usually receive the combined loads from more than two directions. In the future, using the motion simulation software (such as ADAMS) to test and verify the power system loading condition in accelerate, braking and cornering, etc, and would be able to do a more accurate assessment.
