Angular Measurements for Complete Rotational Cycles

Christopher_Fadanelli

By default, in MotionView, angular rotation is recorded as the total amount of rotation traveled. For instance, with this four-bar linkage, the output to retrieve the angular rotation of a joint is computed using RTOD({j_0.AZ}).

Current Outcome:

 

Observe that the recorded rotation is given as the total travel, not in cycles. To adjust the measurement to display rotation in cycles, the <a href="https://help.altair.com/hwsolvers/ms/topics/solvers/ms/mod.htm" target="_blank" rel="noopener">MOD</a> function can be used. The output can be updated to RTOD(MOD({j_0.AZ}, 2*PI)), which will record the angular rotation within a 360-degree cycle.
