| 摘要 | PURPOSE:To avoid the generation of an error of a higher order mode at the time of a response calculation, and to improve the experimental accuracy by giving an attenuation of the vicinity of the highest order mode of a response of a specimen as a larger value than others, as an attenuation term of a mathematical expression model of the specimen. CONSTITUTION:A displacement target value Xa of a specimen 1 is derived by executing a response calculation by a target value operator 5, based on a load quantity Fa of a displacement loading device 2a for giving a displacement of a prescribed vibration mode by applying a force to the specimen 1, and a mathematical expression model of the specimen 1 given from a constant setting device 6. In this case, to an attenuation term of the mathematical expression model, an attenuation factor of the vicinity of the highest order mode of a response of the specimen 1 is given as a larger value than others. Subsequently, from a displacement target value Xa and a displacement quantity Ya of the specimen 1, a displacement command value Va given to the specimen 1 is calculated by a displacement controller 7, and also based on a deviation of said value and a displacement quantity Wa of the displacement loading device 2a, a load quantity is controlled. | ||||||
