Summary:Apparatus and method for the sinusoidal vibration testing of articles in which a fluid spring of an adjustable stiffness is disposed between a test table with a test specimen thereon and a mechanical reciprocator. The stiffness of the fluid spring controls the amplitude of vibration transmitted to the test specimen. By adjusting the opposing fluid pressure on either side of a piston or by adjusting volumetric capacity of the chamber on either side of the piston, the stiffness of the fluid spring can be regulated.
