In present embodiment, under stationary state, to applied the vibration (maximum 100Hz left and right) of vertical and the vibration (maximum 100Hz left and right) of horizontal direction by test body TP.In addition, under floating state, to applied the vibration (maximum 1kHz left and right) of vertical and the static load of horizontal direction by test body TP.
First, with reference to Fig. 5～Fig. 7, the load test under stationary state is described.
As shown in Figure 5, Figure 6, if test implementer is to the operation of the not shown operating portion input regulation of load experimental device 1, control part 90 makes a plurality of fastening cylinder device 61 actions and becomes stationary state under the state in benchmark posture and reference position at weight 40.And the test model of control part 90 based on reading from storage unit controlled vertical driver 20, and the maintaining part 71 of below is moved and quilt is tested to the vibration that body TP applies vertical by piston 22.Now, the signal that the load of control part 90 based on from force cell 73 is corresponding, to carry out FEEDBACK CONTROL to applied the mode of the load (vibration) of target by test body TP.
In addition, control part 90 is based on test model level of control direction driver 30, and the maintaining part 72 above making by piston 32 moves and quilt is tested to the vibration that body TP applies horizontal direction.Now, as shown in Figure 7, mobile corresponding with the maintaining part 72 of horizontal direction driver 30 caused tops, produces at weight 40 power of wanting to make it rotation.
Yet, because weight 40 is fixed on cross-peen 13(, framework 10), thereby by framework 10, stop the power of wanting to carry out above-mentioned rotation, and keep weight 40 reference position and benchmark posture.
Next, with reference to Fig. 1, Fig. 2, Fig. 8, Fig. 9, the load test under floating state is described.
As shown in Figure 1 and Figure 2, if test implementer inputs predetermined operation to the not shown operating portion of load experimental device 1, control part 90 is removed the action of a plurality of fastening cylinder device 61 and becomes floating state.And the test model of control part 90 based on reading from storage unit controlled vertical driver 20, and the maintaining part 71 of below is moved and quilt is tested to the vibration that body TP applies vertical by piston 22.Now, the signal that the load of control part 90 based on from force cell 73 is corresponding, to carry out FEEDBACK CONTROL to applied the mode of the load (vibration) of target by test body TP.
In addition, control part 90 is based on test model level of control direction driver 30, and the maintaining part 72 above making by piston 32 moves and quilt is tested to the static load that body TP applies horizontal direction.Now, as shown in Figure 8, mobile corresponding with the maintaining part 72 of horizontal direction driver 30 caused tops, produces and wants to make it the power of rotation and make weight 40 rotations at weight 40.
For example, as shown in Figure 8, when the piston 32 of horizontal direction driver 30 is with from the outstanding mode of cylinder barrel 31 moves, weight 40 right side part moves downwards, and left part is moved upward, and turn clockwise (arrow R).Like this, the distance detecting in tilt detection sensor 81 is wider, the distance detecting in tilt detection sensor 82 is narrow, based on the detected distance of these sensors, control part 90 detects weight 40, and with respect to moving direction H1Xiang bottom right (soft support unit 52 sides in below decline), (A in the S110 of Fig. 9) tilts.And the soft support unit 52 in below that control part 90 is controlled as making to configure expands, and control soft support unit 51 atrophys in below for the side configuration that makes to keep left on the right side, to eliminate the inclination of weight 40, become benchmark posture (S130).
In addition, now, the situation that has weight 40Cong reference position to misplace to the left.In this situation, the distance detecting in position-detection sensor 84 is narrow, the distance detecting in position-detection sensor 85 is wider, based on the detected distance of these sensors, control part 90 detects (soft support unit 55 sides in the side) skew (B in S140) to the left of weight 40Cong reference position.And control part 90 is controlled soft support unit 56 atrophys in side for making to configure on the right side, and the soft support unit 55 in side of controlling as the side configuration that makes to keep left expands, to eliminate the dislocation of weight 40, becomes reference position (S150).
In addition, for example, contrary with Fig. 8, after the piston 32 of horizontal direction driver 30 moves in the mode of the cylinder barrel 31 that submerges, the left part of weight 40 moves downwards, right side part is moved upward and be rotated counterclockwise (reverse direction of arrow R).Like this, the distance detecting in tilt detection sensor 81 is narrow, the distance detecting in tilt detection sensor 82 is wider, based on the detected distance of these sensors, control part 90 detects weight 40 (soft support unit 51 sides in below decline) inclination (B in S110) to left down.And control part 90 is controlled as making soft support unit 51 expansions in below of side configuration that keep left, and controls soft support unit 52 atrophys in below for making to configure on the right side, becomes benchmark posture (S120) to eliminate the inclination of weight 40.
In addition, now, the situation that has weight 40Cong reference position to misplace to the right.In this situation, the distance detecting in position-detection sensor 84 is wider, the distance detecting in position-detection sensor 85 is narrow, based on the detected distance of these sensors, control part 90 detects (soft support unit 56 sides in the side) skew (A in S140) to the right of weight 40Cong reference position.And control part 90 is controlled as making soft support unit 55 atrophys in side of side configuration that keep left, and the soft support unit 56 in side of controlling as making to configure on the right side expands, to eliminate the dislocation of weight 40, becomes reference position (S160).
In addition, under floating state, for example, if under the state (having applied the state of static load) of maintaining part 72 single-way movings above being made by horizontal direction driver 30, by vertical driver 20, made maintaining part 71 vibration of below, have weight 40 to orthogonal directions H2(Fig. 1, Fig. 8 nearby-depth direction) tilt and produce situation about swinging.Now, the distance of control part 90 based on detecting in tilt detection sensor 83 controlled, if it is less than the reference range of regulation to detect this distance, soft support unit 54 sides in the below of weight 40 are with the mode declining tilt (B in S170), and soft support unit 54 expansions (S180) below making, or, if it is larger than the reference range of regulation to detect this distance, soft support unit 54 sides in the below of weight 40 in the mode that rises (, relatively, the mode declining with soft support unit 53 sides in the below of weight 40) (A in S170) tilts, and soft support unit 54 atrophys (S190) below making.Like this, by by soft support unit 54,53 supportings in below, to restrain the mode of the swing that weight 40 produced, control.
In addition, control part 90, when the inclination of weight 40 on moving direction H1 not detected (C in S110), maintains its state.That is, do not carry out the control for the soft support unit 51,52 in below.In addition, when the dislocation of weight 40 on moving direction H1 not detected (C in S140), maintain its state.That is, do not carry out the control for the soft support unit 55,56 in side.In addition, when the inclination of weight 40 on orthogonal directions H2 not detected (C in S170), maintain its state.That is, do not carry out the control of the soft support unit 54 in below.
