Abstract
A test system (20) has: a base (30); first and second support posts (40A, 40B) extending upward from the base; and a crosshead (44) receiving the first and second support posts. The crosshead is movable along a vertical range of motion relative to the first and second support posts and lockable to the first and second support posts within that range of motion. An actuator (70) provides a vertical force between the base and the locked crosshead. The vertical force is converted to a horizontal force on a specimen (26).
Claims20
A test system (20) comprising:
- a base (30);
- first and second support posts (40A, 40B) extending upward from the base;
- a crosshead receiving the first and second support posts, the crosshead:
- movable along a vertical range of motion relative to the first and second support posts;
- and
- lockable to the first and second support posts within that range of motion;
- and
- an actuator (70) for providing a vertical force between the base and the locked crosshead, and further comprising:
- means (22) for converting the vertical force to a horizontal force on a specimen (26).
A vertical test system adapter (22) for testing a specimen (26), the adapter comprising:
- an upper pivot block (120A) and a lower pivot block (120B);
- first and second guides (110A, 110B) for slidingly receiving first and second support posts, respectively;
- first and second horizontal rails (108A, 108B) each mounted to the first and second guides;
- first and second horizontal guides (102A, 102B) each slidingly receiving the first and second horizontal rails;
- first and second upper pivot arms (122A, 122B) respectively having outboard end portions pivotally mounted to the first and second horizontal guides and having inboard portions pivotally mounted to the upper pivot block;
- first and second lower pivot arms (124A, 124B) respectively having outboard end portions pivotally mounted to the first and second horizontal guides and having inboard portions pivotally mounted to the lower pivot block;
- and
- first and second fixtures (104A, 104B) for mounting the test specimen to transmit a horizontal force between the first and second horizontal guides through the test specimen in response to a vertical force applied across the upper pivot block and lower pivot block.
