This report discusses the use of specialized analytical procedures that can be used to predict the structural behavior of ROPS and machine frame systems subjected to testing as described in SAE Recommended Practice J1040. For practical reasons, these complex calculations require the use of computerized methods. Specific approaches that are thought to be essential to preparing accurate analytical predictions are described. The importance of an experienced ROPS analyst is reviewed.

The use of analytical procedures to predict the performance of ROPS is especially desirable for ROPS designed for installation on very large off-road machines, where problems of testing are extraordinarily great, and for predicting the effects of changes to proven ROPS designs before retesting.

This report also covers the use of these analytical techniques as ROPS design tools.
