Disclosed are a friction and wear test system and a friction and wear test method. To reduce the error of measured friction coefficients, the friction and wear test system of the present disclosure includes a rotating shaft, a dynamic specimen mounting structure mounted on the rotating shaft, a first static specimen mounting structure, a first loading module for applying a preset loading force to the first static specimen during the test, and a second static specimen mounting structure arranged directly opposite to the first static specimen mounting structure in the axial direction of the rotating shaft. The second static specimen mounting structure is configured with a second loading module for applying a preset loading force pointing at the dynamic specimen to the second static specimen during the test, so as to at least partially counterbalance the force loaded on the dynamic specimen by the first static specimen during the test.

The disclosure relates to apparatus and methods for uniaxial testing of a solid specimen, such as an asphalt or asphalt concrete specimen. The apparatus provides a simplified and accelerated procedure for mounting and testing asphalt mixture samples and other solid specimens under uniaxial tension and/or compression, in particular to measure corresponding uniaxial strain and/or fatigue in the specimen. The apparatus incorporates two opposing collet-chuck elements to rapidly mount and fixedly hold a solid specimen in place in a loading system to apply uniaxial loads. The disclosure further relates to an off-specimen means for measuring strain in a specimen using optical imaging in which successive time series images of a specimen during uniaxial loading can be analyzed to determine displacements and corresponding strains.

An apparatus for testing solar panel modules that includes a support frame, a test bed fixedly connected to the support frame and configured to connect with a solar panel module, and a load testing device mounted to the support frame. The load testing device includes a positioning device mounted to the support frame, an actuator hingedly fastened to the positioning device, and an arm having a first end rigidly fastened to the actuator and a second end opposite the first end. The arm extends away from the actuator. A load cell is fastened to the second end of the arm, and a universal joint is fastened to the load cell. A plate is hingedly connected to the universal joint, and a suction cup is rigidly engaged with the plate. A pneumatic system connection is incorporated within the actuator, and a vacuum system connection is incorporated within the suction cup.
