1. A system for applying loads to a test specimen, the system comprising:
- a controller;
an actuator operatively coupled to the controller to operate based on control signals therefrom and adapted to apply loads or control displacement of a test specimen;
one or more transducers that provide signals to the controller indicative of at least one of measured loads or measured displacements on the test specimen; and
wherein the controller is adapted to control said actuator based on signals from at least one of the one or more transducers and a predetermined representation of additional aspects of the test specimen for generating at least one of a simulated load or a simulated displacement.

Abstract
A system and method to expand capabilities of simulation and durability testing of a specimen under test utilizing a virtual signal that is generated by combining the actual measured signal from a transducer with a supplemental or simulated signal created by a function based on position, load or another known or measurable parameter. This virtual signal may then be inserted into a control loop to adapt the system to this new, calculated or combined signal.

8. A method for applying loads to a test specimen, the method comprising:
-
making one or more measurements on a test specimen of at least one of one or more loads or one or more displacements; controlling an actuator coupled to the test specimen to apply at least one of one or more loads or one or more displacements on the test specimen by combining information indicative of the measurements with corresponding simulated information representative of additional aspects of the test specimen, to produce virtual representations of additional aspects of at least one of loads or displacements that are used to control the actuator. - View Dependent Claims (9, 10, 11, 12, 13)

14. An orthopedic test system for applying loads to a test specimen, the system comprising:
-
a controller; an actuator operatively coupled to the controller to operate based on control signals therefrom and adapted to apply loads or control displacement of an orthopedic test specimen; one or more transducers, selected from among one or more load transducers and one or more displacement transducers, wherein the transducers provide signals to the controller indicative of measured loads or displacements on the orthopedic test specimen; and wherein the controller is adapted to control said actuator based on signals from at least one of the one or more transducers and a representation of additional aspects of the orthopedic test specimen for generating simulated loads and/or displacements. - View Dependent Claims (15, 16, 17, 18, 19, 20)
