ACCUMULATION DAMAGE DEGREE EVALUATION SYSTEM, REPRODUCED ENERGY TYPE POWER GENERATOR, ACCUMULATION DAMAGE DEGREE EVALUATION METHOD, AND HYDRAULIC MACHINE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an accumulation damage degree evaluation system for a hydraulic machine, which is enabled, by considering the running state of each hydraulic chamber properly in an entire evaluation period, to evaluate the total accumulation damage degree of each evaluation point of a cylinder block for the entire evaluation period.SOLUTION: An accumulation damage degree evaluation system for a hydraulic machine including a plurality of pistons and at least one cylinder block, comprises: an availability information acquisition part constituted to acquire the availability information indicating the availability of each hydraulic chamber for an evaluation period; and a total accumulation damage evaluation part constituted to evaluate the total accumulation damage degree of each evaluation point of the cylinder block for the entire evaluation period on the basis of the availability information acquired by the availability information acquisition part.
