摘要： The present invention discloses a testing system and a testing method for a structure which tests a structure made of a test piece structure and a numerical model virtually connected to the structure. A simulated structure including a frame, an actuator and a reaction force measuring device is mounted on a foundation on which a shaking table is also mounted. Only the test piece structure is mounted on the shaking table. The motion of the shaking table 5 which is generated at the time of shaking the test piece structure using the shaking table and the actuator is measured by a shaking table motion measuring device, while the reaction force generated by the test piece structure is measured by a reaction force measuring device. Using these measured values and the numerical model stored in a digital computer, the motion of the test piece structure after a predetermined period for the motion of the simulated structure is calculated. The actuator and the shaking table are driven so as to make this calculated motion.

摘要： A shaking response is estimated with high precision by performing a shaking test f or combining and estimating a shaking characteristic of a partial structure of an object under test obtained through a shaking test and a shaking response of the whole structure which is numerically modeled. In a shaking test apparatus and method, a structure under test comprises a partial structure and a numerical model which is virtually connected to the partial structure. First, a vibration model corresponding to the partial structure is assumed, the numerical model and the vibration model are combined to construct an overall-system model, and then the vibration response of the overall-system model is calculated. On the basis of the calculation result and the signal input from a waveform oscillator, the partial structure is shaken by using a shaker. The displacement and reaction force of the partial structure are measured by a displacement gauge and a load cell, the vibration model is corrected on the basis of the measurement value and the overall-system model is reconstructed. This procedure is repeated to construct the overall-system model with high precision.

摘要： A simulation apparatus for simulating vehicle movement during actual running has a mock vehicle that is provided with a truck and a vibrator, and a numerical model that is virtually connected to the mock vehicle and stored in a digital computer. Wheels are joined to the bottom portion of the truck, and a driving machine for rotationally driving the wheels is provided under the wheels. The driving machine drives the wheels in such a manner as to simulate a running surface such as a road or rails. The rotation of the wheels causes the truck to generate reaction force. A reaction force measuring device measures this reaction force. Based on a resulting measurement value and the numerical model stored in the digital computer, the digital computer calculates a vehicle movement after a lapse of a preset time. A controller controls the vibrator so as to realize the calculated vehicle movement.
