ABSTRACT:
A vibration testing apparatus which is minimized in size and capable of being assembled with ease includes a vibrating section (11), a vibration generator (10), and a transmitting section (21) for transmitting vibrations from the vibration generator (10) to the vibrating section. The transmitting section (21) is formed with a pair of opposed parallel pressure-receiving plates (23, 24) that are orthogonal to the direction of vibrations, with the vibrating section (11) interposed between the pressure-receiving plates. The vibrating section (11) is formed with pressure-bearing surfaces (14) in opposed parallel relation to the pair of pressure-receiving plates (23, 24). High pressure fluid is fed into clearances (16), defined between the pressure-receiving plates (23, 24) and the pressure-bearing surfaces (14), to form a static pressure bearing. The pressure-receiving plates (23, 24) are clamped by a connecting member (25) under a load whose value enables the static pressure bearing to function as a spring.
