MOLA Laser Housing Input Test Specification

X-direction Input

Following are the X-direction test specification input levels that were derived from the analytical responses. The table gives the values that are plotted in the chart. Recall that the Grms value is the area under the curve and represents the root mean square value of the acceleration.
