Abstract
A support apparatus for a modal test and a using method thereof. The support apparatus includes: a suspension structure () configured to suspend a test unit (); and a support structure disposed under the suspension structure () and configured to support the test unit (). The suspension structure () and the support structure are matched to cause a stiffness of the support apparatus for a modal test to be zero. The support structure includes an anti-stiffness rhombus-shaped frame (), a scalable sleeve, a horizontal elastic component (), and a base (). The scalable sleeve is connected to the anti-stiffness rhombus-shaped frame () and the base () respectively, and the horizontal elastic component () connects two diagonal points of the anti-stiffness rhombus-shaped frame ().
