摘要： PROBLEM TO BE SOLVED: To provide a load testing machine capable of performing a fatigue test at a high frequency, also performing a static test, and simply changing a resonance frequency.
SOLUTION: The load testing machine comprises a trestle (1); at least one pair of supports (3) erected on the trestle; a crosshead (4) bridged between the supports (3); and an actuator (11) provided on the trestle or a crosshead. Additionally, a specimen (12) is mounted between the crosshead and the trestle and load is applied to the specimen by the actuator. Then, the crosshead is mounted to the support via a spring material (6) and achieves a change in the connecting position between the spring material and the crosshead or that between the spring material and the support. Changing the connection position allows the resonance frequency to be changed.

摘要： PROBLEM TO BE SOLVED: To reduce an offset load applied to a test piece and at the same time miniaturize a test piece-gripping apparatus and reduce its weight.
SOLUTION: A lower screw flange 4 where a test piece 1 is screwed is fixed to a lower chuck body 2 via a spacer flange 3 by using a bolt 5. A plurality of members comprising a plurality of laminated belleville springs 10 and belleville guides 11 are provided on the spacer flange 3. In a state before clamping by a bolt, the tip of the belleville guide 11 projects from the upper surface of the spacer flange 3 by D, so that a gap is formed between the lower screw flange 4 and the spacer flange 3. By clamping the bolt 5 so that the gap is eliminated, an offset load applied to the test piece 1 can be eliminated. A flange 16 that is fitted to the upper screw flag 16 is mounted by a bolt 17 to eliminate the same gap also for the upper chuck.

摘要： PROBLEM TO BE SOLVED: To make it possible to perform the measurement for a long effective measuring time by loading a dynamic load or an impact load, which is stable for a long time in the broad velocity range by constituting a load measuring means of a sample- hitting small protruding part, which is protruding on the surface of a base part, and a base-part insulating means, which cuts out the propagation and the transmission of stress waves between the base part and an external part. SOLUTION: An impact block 12 is formed in a cylindrical shape. At a lower surface 12a of the block, a small protruding part 14 on the side of the impact block having the same material is formed as a unitary body. The test is performed by hitting a sample 10 with the small protruding part 14. A stress-wave insulating material 16 is provided between the impact block 12 and a driving cylinder 11. As the ingredient of the stress-wave insulating material, the ingredient having the sufficiently small acoustic impedance with respect the acoustic impedance of the impact block 12, e.g. rubber, plastic or the like, is selected. Then, the small protruding part 14 hits the sample by the lowering of a piston rod 11a. The impact force caused by the impact is measured with a strain gage 24, and the displacement amount of the sample 10 is measured by a displacement gage 33.

摘要： PROBLEM TO BE SOLVED: To prevent water leakage and generation of noise during a high speed rotation by forming each roller out of a plurality of disks, and overlapping the respective disks each other at certain intervals in the axial direction of the respective rollers. SOLUTION: On the endless flat belt 5 arranged in the uppermost part of four shaking devices 3 in a road simulator 2, respective tires 4 of a testing vehicle 1 are placed, and the belt 5 serves as a substitute for road surface. A driving characteristic of the vehicle can be tested in the condition similar to an actual road condition, when the shaking devices 3 including the belt 5 are used so as to vibrate the belt 5 in the vertical direction, the wheels of the vehicle 1 are rotated at the ordinary rotational speed, and a steering wheel is turned so as to change the directions of the tires 4. Since the distance between the belt 5 and contact point of each roller in the belt advancing direction can be shortened without any reduction in the diameter of an intermediate roller, generation of noise can be prevented even when the belt 5 is rotated at a high speed.

摘要： PURPOSE:To solve such problems that a high frequency vibration is impossible because a vibration waveform and a vibration amplitude of a vibrator are not correctly transmitted to a vibration stage, and that the vibration stage is inclined due to a displacement of the center of gravity of a sample, etc. CONSTITUTION:Both ends of a vibrator 49 vibrating in the up-and-down direction are supported at ball bearings 48, 47 set at a bed 40 and a vibration stage 46. A horizontal bell crank 44 and a vertical bell crank 45 are set at both end parts of each of two hollow shafts of a large diameter which is supported at both ends thereof by a bearing 42. Both ends of a supporting rod 53 are supported by ball bearings 51, 52 set at the vibration stage 46 and horizontal bell crank 44. The vertical bell cranks 45 of the hollow shafts of a large diameter are coupled with each other by a coupling rod 54. A vibrator 64 (73) in X (Y) direction is coupled to the vibration stage 46 via a bell crank 57 (69) and a vibrator rod.
