摘要： A sensing apparatus for sensing at least two physical quantities is disclosed. The sensing apparatus includes a first transducer (62, 122, 212) that provides a first output signal proportional to a first measured quantity and a second transducer (64, 155, 214) that provides a second output signal proportional to a second measured quantity. An excitation regulator device (82, 140, 162) is connected to the first transducer (62, 122, 212) and the second transducer (64, 155, 214). The excitation regulator device (82, 140, 162) provides an excitation signal to the second transducer (64, 155, 214) so that the second transducer output signal is referenced to the first transducer output signal in order to obtain a resultant output signal which is a combination of the first and second output signals.

摘要： Provided is a residual stress estimation method and a residual stress estimation device capable of suppressing the number of cut pieces to be collected for measuring inherent strain without deteriorating residual stress estimation accuracy.
In a case where it is assumed that the inherent strain is uniformly distributed in one direction in a structure, a user measures residual stress from a cut piece collected in a region in which the inherent strain is uniformly distributed and inputs the measured value to the residual stress estimation device. The residual stress estimation device estimates a two-dimensional inherent strain distribution on an analysis surface perpendicular to the one direction in the structure using the input residual stress measured value, transfers the estimated two-dimensional inherent strain distribution to the one direction, and estimates a three-dimensional inherent strain distribution in the structure.摘要翻译： 提供一种残余应力估计方法和残余应力估计装置，其能够抑制为了测量固有应变而收集的切割片的数量而不降低残余应力估计精度。 在假定固有应变在结构中的一个方向上均匀分布的情况下，用户测量来自在固有应变均匀分布的区域中收集的切片的残余应力，并将测量值输入到残余部分 压力估算装置。 残余应力估计装置使用输入的残余应力测量值来估计结构中垂直于结构中的一个方向的分析表面上的二维固有应变分布，将估计的二维固有应变分布转移到一个方向， 结构中的三维固有应变分布。

摘要： The invention relates to a configuration (1) of a component (2) and at least one test device for recording a degradation (4, 40) of said component. Said test device has at least one electric oscillating circuit (31) and the component and oscillating circuit are interconnected in such a way that the degradation of the component causes a degradation (41) of the oscillating circuit and a modification of a detectable resonant signal of the oscillating circuit. The configuration is characterised in that the test device has at least one additional oscillating circuit (32) comprising an additional detectable resonant signal and that the oscillating circuit and the additional oscillating circuit are coupled to form a comprehensive oscillating circuit (30) comprising a detectable comprehensive resonant signal that differs from the resonant signal and the additional resonant signal. The inventive component is for example a heat shield (20) of a combustion chamber in a gas turbine. The oscillating circuits are connected in parallel. Different high-frequency signals are received for an intact oscillating circuit and for a degraded oscillating circuit. The oscillating circuit consists of a brittle ceramic conductive material. A crack (degradation) in the heat shield continues as a crack in the oscillating circuit. The measuring signal received permits the degradation of the component to be reliably detected.

摘要： Provided is a searching method for acquiring ground information by mounting a resistor on the leading end of a rod and by piercing the ground with the same. The searching method acquires the ground information on the strength and deformation of the ground, by piercing the ground with the resistor including a frustum of a circular cone or an arcuate member containing a deficient sectional shape, in which the angle made between the side face of the resistor having blades in the same direction as the piercing direction is 5° or less, upward or outward from the leading end of the resistor, thereby to measure a plurality of transverse ground reactions, and by rotating the resistor having the blades at that depth thereby to measure a plurality of ground shearing forces. The main information such as C, ϕ and E can be determined in the ground search by inserting an apparatus of one kind into the search depth without moving it up and down. Thus, an original position ground search can be performed speedily and lightly and applied to various grounds.
