<p><P>PROBLEM TO BE SOLVED: To provide a material testing machine and a hydraulic adjustment method for the material testing machine capable of efficiently reducing power consumption. <P>SOLUTION: A controller 40 includes: a preliminary test data processing unit 70 for processing data collected in preliminary tests; and a control value calculation unit 80 for calculating a control value to be transmitted to a control board 31 etc. as a command during the testing of a material test. Various kinds of parameters acquired in the preliminary tests are stored in a storage device etc. in a computer 43, and used in control value calculation to be performed by the controller 40 for the revolution speed adjustment of a motor 34 and supply pressure adjustment so as not to consume excessive power in an actual fatigue test. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
