Relative Movement Analysis (New analysis method for stress analysis during resonance frequencies called RMA)
Relative movement analysis is based on 3 measurement points and acceleration sensors, a physical triangle is exactly measured first in static condition and during measurement with added amplitudes and phases on same time axis.
After exporting / importing these channels to RMA calculation program developed by Reino, the relative movements in space between these points are calculated.
Through this analysis stress level can be contributed and even given in FE analysis to find out the durability factors, and often how to improve the structure support or structure itself.
This method has been used several years by Reino to contribute the effects of different engines to chassis, needed changes in exhaust systems and hanger positions, engine mounting optimizations, Formula 1 component dyno problem solution, statical dynos for different sensor investigation etc etc.
