摘要： A test system for testing a specimen include (a) a set of actuators for applying a desired time history of load to a specimen, (b) a drive unit connected to each actuator, (c) power generating elements (current/pneumatic/hydraulic) and (d) a controller connected to the drive units, the controller generates a drive signal for the drive unit based on feedback received from output of the specimen and an error derived from the feedback and an input command. The controller generates the drive signal by compensating varying system parameters which are introduced due to nonlinear response of the test system and the specimen, wherein the controller does not require (i) additional measured variable other than a feedback received from the specimen and (ii) a numerical model of the test system and the specimen.

摘要： The present invention relates to a force measurement device that includes mechanical amplification of linear elastic deformation along the axis of loading by estimating the quasi-linear incremental displacement between two points on arcs inscribed due to angular movements of a pair of cantilever arms located on opposite quadrants on a closed contour load sensing element to improve the sensitivity, and hence the resolution, of the force measurement device.

摘要： The present invention relates to an integrated system and method for in-situ 3-axis scanning and detecting defects in a CFRP composite (150) being loaded under static and cyclic test conditions. The system comprises a test system integrated with (10) a scanning system (20) that comprises a probe assembly (52) to generate eddy current on the surface of the CFRP composite (150) mounted on the test system, and a 3D scanner assembly (60) for movement of the probe assembly (50) over the entire surface area of the CFRP composite (150) along X-axis, Y-axis and Z-axis. An operator console (70) is connected to the test system and the scanning system (20) for controlling (3) mechanical test process in the test system and for controlling 3-dimensional movement of the probe assembly (52) along X-axis, Y-axis and Z-axis in a synchronous manner. Such system and method achieve (3D) automated and synchronized 3D scanning of the CFRP composite (150) to accurately detect the defects in the CFRP composite (150) before/during/after mechanical testing without interrupting the mechanical test process.
