Vibration Testing

General:

• K+ test facilities are visibly clean; however, they are not classified as cleanrooms.

• K+ test engineers manage setup, operation, and shutdown of K+ test equipment. The customer is responsible for operations of their unit under test (UUT).

• Daily rate assumes 8 hour days and applies to setup, test, and teardown operations.

Operations:

• Vibration test fixtures to attach the UUT to the K+ vibration table shall be provided by the customer. See image below for head expander, slip table, and armature hole patterns.

• The vibration test fixture shall be designed such that the Unit Under Test (UUT) test axes are aligned with the edges of the horizontal slip table.

• Since the horizontal slip table provides only a single degree of freedom, it will be necessary to rotate the fixture and/or UUT by 90 degrees between tests to excite both horizontal axes.

• The vibration test fixture shall be designed with no structural modes below 2500 Hz. Please coordinate with K+ if this is not achievable.

• K+ DAQ system supports 16 channels for response accelerometers. 4 triaxial and 4 uniaxial response accelerometers are supplied by K+.

• K+ supports accelerometer installation on the UUT using either adhesive or tapped mounting holes. If tapped holes are to be used, the UUT must be delivered with these holes prepared in advance.

• Powered operation of the UUT during vibration shall be coordinated on a case by case basis with K+ test personnel.

• Customers may connect an oscilloscope or similar monitoring equipment to their UUT to monitor for inadvertent power-up during vibration.

• Test data will be delivered within 48 hours of test completion.
