Accelerometers install and connect according to the procedures described in the specific sensor manual. Accelerometers utilized for impact testing include the 353 Series of single axis accelerometers, and the 356 Series of triaxial accelerometers. For additional information regarding sensors to meet your impact testing needs, feel free to contact the ®... -
Page 9: Testing
® ® ’s ICP constant-current power supply units provide the necessary excitation power for proper operation of the Modal Punch. These units provide the correct power and have circuit fault indicating meters and a bias decoupling capability to remove MOSFET turn on bias voltage from the measurement signal. -
Page 10: Calibration
C. To increase signal energy of impact, increase the impact velocity and/or hammer mass. 5). Repeat steps 1 through 4 until satisfactory results are obtained. Generally speaking, the impact tips affect the impulse frequency content, while the mass of the impact device and velocity of impact affect the signal energy level. Frequency content and energy level are interrelated. -
Page 11: Maintenance
The Modal Punch can be calibrated by hitting a freely-suspended mass instrumented with a quartz reference accelerometer. The mass, pendulously suspended or placed on a piece of foam rubber, will behave as a rigid body. According to Newton’s second law of motion, at any instant in time, the force experienced by the mass is simply the mass multiplied by the measured acceleration. -
