In our last several discussions, we have seen how cycle profiling offers a systematic approach to fluid power design (see September 2007, Diesel Progress) and how load analysis can be considered the key to cycle profiling and parametric definition. Now we'll continue by looking at dynamic conditions in circuits, such as overrunning and inertial loads.
A cycle profile for the transfer application of Fig. 1 is shown in Fig. 2. It is based on a quantitative, steady-state analysis of the example problem we have been discussing and would be analogous to the profile for one linear actuator in the excavator problem we discussed earlier.
We have so far ...
