6.0 TEST PROCEDURES AND RESULTS I
6.1 Specimen Mounting Procedures g
The specimens, as descrit. in Paragraph 5.0 and shown in Photographs 1 through 6, premounted in a Corporate Consulting-fabricated test fixture, were installed on the Wyle Multiaxis Seismic Simulator Table. The test fixture was welded to the test table such that the specimens were oriented in the longitudinal axis colinear with that of the test table (Photographs 1 and 2). The test fixture was rotated 90 degrees for the second axis of testing (Photograph 3).
The mountings si=ulated as closely as practical their actual in-service mountings.
The Balancing Ca=per was preset to an approximate 45-degree throttling position and locked in place using the manual locking quadrant. A 3/8-inch diameter bungee cord was attached to the center of one blade and the other end attached to the test table (Photograph 1) to simulate a 45-pound air load.
6.2 Resonant Search Procedures A low-level (approximately 0.2 g horizontally and vertically) biaxial sine sweep was performed to establish resonances in both the longitudinal /
vertical and the lateral / vertical test crientations.
The sweep rate was one octave per minute over the frequency range of 1 H: to 35 H.
6.7.1 Resonant Search Results I
Table I contains the test run descriptions and the input accelerations.
The transmissibility plots of the speci=en response accelerometers from the resonant search tests are presented in Appendix I.
6.2 Multifrecuency Test Procedures The specimens were subjected to 30-second duration simultaneous horizontal and vertical inputs of randem motion consisting of frequency bandwidths j
spaced one-third octave apart over the range of 1.0 H: to 40 H: as necessary to envelope the RRS.
The amplitude of each one-third octave frequency was independently adjusted in each axis until the TRS enveloped the RRS.
The control accelerometers were recorded on tape and oscillegraph recorders. The resulting table mot'icn was analy ed by a spectrum analyzer at a damping of one percent (1%) and plotted at one-third octave frequency intervals over the frequency range of interest.
e Five (5) OBE (two-thirds-level SSE) tests, followed by a full-level SSE were performed in both the lateral / vertical and the longitudinal /
- test, vertical orientations.
The SSE RRS are es shown in Figures 1 and 2.

It was demonstrated that the specimens possessed sufficient integrity to withstand, without comprcmise of structures, the prescribed simulated seismic environment.
TRS plots of the control acceleremeters from one of the OBE tests and the SSE test in each orientation are presented in Appendix II.
6.4 Specimen Response Procedures Twelve (12) specimen response acceleremeters were located on the specimens under test as shown in Photographs 6 through 11 and described in Table II.
FM tape and oscillograph recorders provided a record of each accelerometez response during the test program. The placement of the acceleremeters wag at the discretion of the Corporate Consulting Technical Representative.
6.4.1 Specimen Response Results The transmissibility plots of the specimen response acceleroneters from the resonant search tests are presented in Appendix I.
The TRS plots of the specimen response accelerc=eters from the SSE test in each orientation are presented in Appendix II.
6.5 Strain Procedures Three (3) uniaxial strain gages were installed on the specimens (Photogr,;
3 and 12 through 14) in areas deter =ined by the Corporate Consulting Techr.
Representative. The cutputs frc= the strain gages were recorded en an oscillograph recorder during the simulated seismic test program.

The smaller value of ml and m2 is defined as,the margin of the equipment.
Critical frequency is defined as the frequency which has the smallest TRS/RRS ratio.
A constant 0.9 is applied to incorporate the 10% increase of RRS.
