1. A system for nondestructive vibrational testing of an object, comprising:

  • load sensor means associated with the object and having an input for receiving a voltage input and an output for providing a sensor output, said load sensor means being responsive to said voltage input and to vibration of said object for generating said sensor output;

    a hardware system connected to said load sensor means and responsive to said sensor output from said load sensor means for acquiring data relative to vibration of the object;

    said hardware system including voltage regulating means connected to the input of said load sensor means for providing a regulated voltage input to said load sensor means;

    said hardware system further including signal conditioning means connected to the output of said load sensor means for receiving and conditioning the sensor output from said load sensor means and capable to provide an amplified signal output, analog-to-digital converter means for receiving said amplified signal output from the signal conditioning means for converting said amplified signal output to a total of 1536 data samples in digital form; and

    a digital computer system responsive to said data samples, said digital computer system including means for selecting 512 data samples from the 1536 data samples, and analyzing the selected data samples.
