It should be noted that the amplitude shown in the plot has been reduced by -9dB. Weir-Jones Engineering Consultants Ltd. 2 30144-REP-001-0. wp9 3. 0 VIBRATION TEST EQUIPMENT The equipment required for the vibration tests was a shaker, a vibration controller and two feedback accelerometers (see Figure 3). The specifications of the equipment used are as follows. Shaker: Manufacturer: Model: Rated Force: Frequency: Maximum Displacement: Maximum Velocity: Maximum Acceleration: Maximum Payload: Driven by: Controlled by: Manufacturer: Model: Serial: Range: Ling Dynamic Systems (LDS) V722 750 lbf. rms (Random) 5 Hz - 4000 Hz 1 inch peak-to-peak 40 inch/sec peak 50g rms (Random) 220 lbs (total weight) LDS PA2000 2kW power amplifier LDS DVC 4000 Mk3 PCB J357B01 (charge capacitance type) 8968, 8969 ±1800 g Accelerometer: The vibration controller and feedback accelerometers were calibrated on March 21st, 2005 by Ralco Inc. in North Haven, Connecticut, in compliance with ANSI/NCSL Z540-1 and traceable to NIST. The calibration certificates of the controller and accelerometers are provided in Appendix 1. Power amplifier Vibration controller Vibration shaker Figure 3: Weir-Jones Engineering Consultants Ltd. Note that the direction of shaker movement is vertical. Weir-Jones Engineering Consultants Ltd. 3 30144-REP-001-0. wp9 As the vibration shaker was designed to translate in the vertical direction only, a set of Aluminum mounting fixtures were used to position the CCTV camera in its two mutually perpendicular axes (Vertical and Transverse) as shown in Figures 4A and 4B. Feedback accelerometers Figure 4A: Vertical orientation mounting of the CCTV camera. Figure 4B: Transverse orientation mounting of the CCTV camera. Weir-Jones Engineering Consultants Ltd. 4 30144-REP-001-0. wp9 4. 0 4. 1 RESULTS Sinusoidal Vibration Test The graphical results of the Sinusoidal vibration tests for the Model CC-02-4. 3 CCTV camera are shown in Appendix 2 located in the back of this report. The interpretation of the lines on each graphical result is as follows: Line Colour Red Dark Blue Light Blue Description Frequency limits and Upper and lower limits of acceleration. Shaker output as measured by the feedback accelerometers. Based on the graphical results, it can be seen that the shaker outputs as measured by the feedback accelerometers corresponded with the defined Sinusoidal vibration profiles within the allowable tolerance specified by the SAE J1455 (August 1994) Standard. [. . . ] No degradation in the quality of the video produced by the camera was noticeable during or after the tests. Therefore the Model CC-02-4. 3 CCTV camera has passed the U. S. Highway Truck Random vibration test in accordance with Method 514. 5 of the MIL-STD-810F (January 2000) Standard.
