Appendix A: Vibration Testing
9.1
Controller Vibration Testing
Danfoss Power Solutions has qualified the controller to the vibration levels for both SAE J1455 and GB/T18488.1-
2015 as stated in the Appendix. The vehicle integrator or manufacturer should ensure that the controller is not
exposed to vibration levels above what has been qualified in testing. Exposure to vibrations above these
qualified levels may lead to damage or failure of the controller.
Danfoss Power Solutions recommends that the vehicle integrator or manufacturer install vibration isolators on
the controller to ensure that vibration levels of the controller are not in excess of the specifications tested
throughout the vehicle’s life. It is the responsibility of the integrator or manufacturer to specify the vibration
isolators and install and maintain the vibration isolators.
9.1.1
SAE J1455 Vibration Test
The controller shall be mounted to the vibration fixture using the four corner mounting holes, with no vibration
isolators. The electrical test equipment will be located next to the vibration table. The unit is unpowered
throughout the test.
The assembly shall be exposed to 3 separate applications, of 3 hours duration, of 1 axis each random profile
vibration per SAE J1455, Figure 10, Bobtail Vertical Mid Frame, Heavy Duty Truck, for a total of 9 hours.
