Test Methods for Multi-Axis Simulation Testing per MIL-STD-810G

One of the primary military standards used for vibration testing has been updated to incorporate multi-axis simulation. The latest revision of this standard is MIL-STD-810G in which the addition of Method 527 allows for real-time road load data to be used for multi-axis simulation. This revision is looking to improve upon the previous vibration test method of single-axis random vibration in each direction. This document will overview the changes to the standard, provide a summary of the previous test methods, detail a test procedure using real-time data for multi-axis simulation, and present the procedure for the testing conducted with this data. In addition, it will help to demonstrate a method for using multi-axis simulation for MIL-STD-810G and help its readers gain a better understanding of this new method.
