发明名称 Piezoelectric-membrane axial oscillator used for measurement of complex elasticity modulus in viscoelastic systems, constrains movement using parallel membranes in rigid casing
摘要 <p>The test head oscillates axially inside a rigid casing, its motion being constrained but not damped, by two parallel membranes. The membranes are monolithically-fabricated plates of high elastic limit, being also torsionally- and radially-rigid.</p>
