Title:
油圧装置の油圧剛性の測定及び使用
Document Type and Number:
Japanese Patent JP6929270
Kind Code:
B2
Abstract:
A method of operating a hydraulic apparatus comprising a hydraulic circuit region and hydraulic machine which is controlled to displace pulses of fluid of known volume into or out of the hydraulic circuit region, generating pulses of pressure in the hydraulic circuit region and torque in the hydraulic machine shaft. The response of parts of the hydraulic apparatus to these pulses is measured and used to determine properties of the hydraulic apparatus. The response of the pressure in the hydraulic circuit region to pulses at different pressures can be used to measure the hydraulic stiffness of parts of the hydraulic circuit region. It is possible to detect faults and to make measurements useful in subsequent operation of the hydraulic apparatus.
