<p>PURPOSE:To restrict the average rate of change of load below the standard rate of change, by increasing the load at the maximum rate of change of load in a vibration zone, and by increasing the load at the minute rate of change immediately after passing the vibration zone. CONSTITUTION:A minute rate of change setting section 11 stores the rate of change of load immediately after passing a vibration zone, which is out-putted to a load setting process section 1. The load setting process section 1 then outputs the load set point to a load adjustment process section 5. When this load set point is within the region of the vibration zone, the load increases at the maximum rate of change of load. But when the load set point is beyond the vibration zone, the load increases at the minute rate of change.</p> |
