摘要： An article and method for measuring strain using a strain gauge made of a shape memory y alloy, and preferably a pseudoelastic alloy, is disclosed. The strain gauge includes an element that preferably is attached to a substrate and mounted on an object, or is woven or stitched to a fabric to measure the strain experienced under an applied stress. The preferred pseudoelastic alloy is Nitinol, which in pseudoelastic form can elongate by up to approximately 8% to accommodate strain in an object or fabric. When woven into a fabric, a Nitinol-based strain gauge can measure strains of up to approximately 20% in the fabric. The strain gauge can be used in such applications as automotive and aircraft seatbelts, parachute canopies and static lines, and commercial cargo nets.

摘要： An apparatus and method for non-destructively determining non-musical physical characteristics such as the Young's modulus, stiffness coefficient, and damping coefficient of a test piece of arbitrary shape. The apparatus consists of a frame having a natural vibrational frequency different from the free vibrational frequency of the test piece, a mechanism for fixing the test piece to the frame, a mechanism for initiating free vibrations in the test piece, a mechanism to measure the displacement of the test piece during the free vibrations, and a mechanism to measure time during the free vibrations. The amplitude, frequency, and decay characteristics of the free vibrations are analyzed mathematically to determine the physical characteristics. The apparatus may include a mechanism to control the initial deflection applied to the test piece. The apparatus may include a mechanism to control the initial load applied to the test piece. The apparatus may include a device such as a computer to collect, process, record, and display the information obtained.

摘要： The present invention relates to a piezo-electric stretching detector which is used for measuring the positive and negative stretching on the surfaces of rigid structures using electric signals, wherein said detector can be attached by a force connection onto said surfaces in a compressible or non-removable relation. This stretching detector has a high sensitivity in all stretching directions and is made of a piezo-ceramic material which is applied in a thin layer on at least one surface of a flexible metal sheet or which is fixedly attached to said metal sheet in the shape of a moulded body. At least one of said stretching detectors can be arranged on the free abutting end of at least one resilient pressure body which is imbedded in the reception housing of a stretching sensor. The stretching sensor further comprises members for pressing the reception housing onto the surface to be measured. According to one method for measuring the positive and negative stretching on the surfaces of rigid structures using a stretching detector or sensor, the piezo-electrically emitted charges are amplified in charge amplifiers so as to obtain output signals which can be used by the controllers and have a voltage proportional thereto. The charge amplifier can also be switched rapidly from reduced charge ranges to very wide charge ranges.

摘要： An apparatus and method of measuring the stress on a work machine is disclosed. A work machine includes a frame, a plurality of ground engaging devices, an operator compartment, an implement having a linkage, an engine, and a stress measurement control system. The stress measurement control system includes a strain gauge sensor, a memory, an electronic controller, and an operator interface. The strain gauge sensor assembly is mounted to the frame or the implement and provides a stress signal indicative of the stress acting upon the frame or the implement. The memory stores a stress signal value and stress limit value. The electronic controller receives the stress signal and the stress limit value, determines whether the stress signal is greater than the stress limit value, and responsively stores the stress signal value in the memory and provides an associated message. The operator interface receives the associated message and provides it to the operator in the operator compartment.
