The present application relates to a kind of creep-fatigue test methods in molten salt environment, it includes to be measured alloy material and is processed into integrated molten salt tank smooth bar sample;To the molten salt tank is filled with molten salt, so that sample gauge section is completely immersed in molten salt;The sample of assembly completion is transferred to fatigue testing machine and installs clamp and measuring device;Test container is evacuated and filled with inert gas, and temperature is raised to test temperature;Using axial strain control mode, trapezoidal wave cyclic load is applied to sample, only at the tensile peak strain setting, the test process is real-time collected test data, until sample reaches failure judgment condition.The present application relies on integrated molten salt tank structure and exclusive loading waveform, so that sample is continuously in molten molten salt environment, can simultaneously carry out creep, fatigue, corrosion coupling test, truly restore material service condition, effectively make up the defect that traditional test cannot simulate multiple damage synergism.

This application relates to the field of artificial intelligence technology, and in particular to a data collection method, apparatus, computer device, and storage medium. The method includes: a terminal acquiring first configuration information; then, when the terminal meets a first triggering condition, sending a request to the network to acquire second configuration information sent by the network, thereby enabling measurement based on the second configuration information and recording measurement data; and then sending a report to a core network connected to the terminal, so that the core network sends the report to a server used to collect terminal model training data. This application standardizes the process of measurement data collection and data reporting, preventing over-collection of data, thus ensuring that the measurement data generated during the measurement process is valid data that meets the model training requirements, avoiding the generation of a large amount of invalid data, and thus avoiding resource waste or network congestion during the processing and transmission of invalid data.

This invention discloses a smoothed finite element adjustable damping implicit integral algorithm for underwater transient acoustic scattering, belonging to the field of underwater transient acoustic scattering numerical simulation technology. First, the computational domain of the underwater transient acoustic scattering field is discretized into a standard quadrilateral element mesh to construct an interpolation scheme for the sound pressure field. Then, each quadrilateral element is divided into multiple smooth domains, and the smoothed sound pressure gradient matrix is ​​obtained through acoustic generalized gradient smoothing technology. Combining differential control equations, the virtual displacement principle, and the Galerkin weighted residual method, the system matrix equation is constructed. An adjustable damping implicit time integral algorithm is used to complete the time-domain discretization, and the numerical results of the transient acoustic scattering field in the entire time domain are obtained through recursive solution. This invention can soften the "overly stiff" stiffness matrix to reduce spatial discretization errors, suppress high-frequency errors through adjustable numerical damping matching, and achieve coordinated control of spatiotemporal errors. Under the same mesh, its accuracy is superior to the standard finite element method, providing an efficient and reliable solution for underwater transient acoustic scattering engineering simulation.

The invention aims to provide a speed cloud picture generation method based on relative coordinates, and belongs to the field of fluid analysis. Comprising the following steps: inputting grid data; selecting and identifying a transformation interval; segment points in the interval are generated based on the interval, and segment type coordinate transformation is completed, wherein the segment type coordinate transformation is divided into data transformation and coordinate transformation; generating a contrastive analysis cloud picture after transformation based on the data and coordinates obtained after transformation; and speed and cloud picture generation and analysis of the relative coordinates are completed. According to the method, generation of the segment points in the interval can be realized, data and coordinate transformation is performed on the segment points, and a new contrastive analysis cloud picture is generated according to the obtained transformed data and coordinates, so that the speed cloud picture is more intuitive in contrastive analysis on the premise of ensuring the accuracy and rationality of the data and the coordinates, and the speed cloud picture is more accurate. And the effectiveness of speed cloud picture contrastive analysis is ensured.
