Abstract: A test device and a method for testing a photovoltaic module, for testing anti-stepping performance of the photovoltaic module. The test device includes first and second test members spaced apart along a first direction. The first and second test members are configured to abut against the photovoltaic module and apply a preset load to the photovoltaic module. The first test member is at a first position when the first test member abuts against the photovoltaic module, the second test member is at a second position when the second test member abuts against the photovoltaic module, and along a movement direction of the first and second test members in a horizontal plane, the first and second positions are alternately spaced apart, to simulate force on the photovoltaic module when an operator walks on the photovoltaic module.

Abstract: A process for autonomous mechanical property testing of specimens on a build plate includes fabricating a plurality of the specimens on a build plate, wherein each of the specimens comprises an upper portion and a lower portion integral to the build plate. Each of the upper portions of the specimens on the build plate are sequentially engaged with an end effector on a terminal end of a multi-linked robotic arm, wherein the end effector is configured to engage the upper portion and apply a uni- or multi-modal load, wherein intermediate the end effector and the multi-linked robotic arm comprises a multi-axis load cell for measuring an applied load. The process further includes autonomously calculating one or more mechanical properties from the applied load.

Abstract: The present disclosure relates to the technical field of springs, and provides a spring, a spring mattress and a spring testing method. The spring includes a helical main body, where the main body is provided with a plurality of spring coils; and a pitch between adjacent spring coils increases gradually from one end of the main body to the other end of the main body. Since the main body of the spring is provided with a plurality of spring coils, and a pitch between adjacent spring coils increases gradually from one end of the main body to the other end of the main body, the spring stressed under an external force can be compressed by stages to provide different feelings for a user, and achieve a better comfort.

Abstract: A signal processing method and a material testing machine are provided. A reference function processing part includes a data interval generation part for cutting out input signal from a load cell into time-domain data interval by cutting out the input signal of a predetermined time length, a reference function determining part for determining a reference function to be used in a transform process, and a transform part for transforming the interval data using the reference function. Considering the approximately straight lines near the two ends of the data interval, the reference function is a third degree polynomial function with tangents overlapping with the approximately straight line at both ends of the data interval.

Abstract: Method of design and manufacturing concrete structures subjected to relevant cyclic loads along their service lives, as wind towers, and a fatigue testing machine. The method consists on the design of concrete structures conditioned by cyclic loads considering a fatigue strength value specified by the project as one of the main design parameters, which will be verified during the manufacturing phase as one of the control parameters of the quality assurance plan by performing fatigue strength test on concrete samples representative of the concrete structural elements produced on said manufacturing phase. The method allows to decouple the concrete fatigue strength from the compressive strength of the material, which is why includes a verification of the fatigue strength as a part of a quality assurance plan of production according to a new developed procedure.

Abstract: A stress corrosion crack test method for evaluating the stress corrosion crack susceptibility of a steel material in alcohol. The method includes filling a cell containing a uniaxial tensile test piece of the steel material with an alcohol solution containing carboxylic acid: 0.1 mmol/L or more and less than 40 mmol/L, chloride ions: 0.05 mg/L or more and less than 300 mg/L, and water: 0.1 vol. % or more and less than 5 vol. %. Additionally, the method includes applying a fluctuating stress at a frequency of 2.0×10−5 Hz or more and 2.0×10−2 Hz or less to the uniaxial tensile test piece in the tensile direction. The maximum stress being equal to or more than the yield strength and less than the tensile strength at a test solution temperature, and the minimum stress being 0% or more and 90% or less of the yield strength.
