Abstract Complex industrial processes usually exhibit multimode characteristics, meaning that statistical features of process data, such as mean, variance, and correlation, vary across different modes. Extracting critical information from these distinct modes can significantly enhance the accuracy robustness data‐driven models in monitoring, condition evaluation, quality improvement. Consequently, identification data becomes a paramount concern modelling. However, existing methods for...
In order to study the mechanical properties of inverted cone bottom oil storage tanks under earthquakes when foundation is uneven, finite element modeling calculation for a 20,000 m3 tank carried out based on ANSYS Workbench. Wind load, hydraulic pressure and seismic load are all equalized as distributed loads with varying spatial positions. Considering various combinations different heterogeneous foundations loads, by adjusting preset bed coefficient, final coefficient maximum settlement...
Hydrogen fuel cells often encounter unstable performance and anomalies during operation, highlighting the need for continuous condition monitoring iterative design improvements. Efficient prediction models are essential assessing of deployed cells, providing valuable feedback enhancing designs developing new products. Machine learning (ML) algorithms widely used to build such models. However, vast operational parameter data hyperparameters without clear physical significance hinder training...
Most industrial grippers now in use are two-fingered. Among them the parallel-jaw gripper is simplest. It can partially remove pose uncertainty of an object through grasping, such as orientation uncertainty. This paper addresses a new type with finger configuration four circles instead two parallel lines. has number important advantages. Especially, it achieves form-closure and confines to locally unique pose, so completely. allows gripped reach this freely without loss required friction...
The substructure method is applied to the dynamic analysis of a train–bridge system considering soil–structure interaction. With this method, integrated train–bridge–foundation–soil divided into subsystem and soil–foundation subsystem. Further, train bridge components. frequency-dependent impedance function transformed time domain by rational approximation simulated high-order lumped-parameter model with masses. equations motion components are established rigid-body dynamics modal...
To exactly study the riding comfort of passengers in urban rail transit trains, a coupling vibration model, including passengers, train, and bridge is proposed this paper. According to Lagrange Equation, differential equations motion each part are derived, which coupled with other through displacement dynamic interaction forces. A corresponding calculation program compiled by Fortran language. representative steel-concrete composite girder on Beijing Metro Line 5 selected as research...
This paper presents a method for calculating the evolutionary power spectral density (EPSD) of seismic response bridges using convolution summation. With zero initial values, formula dynamic component to spatially varying ground motions is derived as summation, by assuming acceleration vary linearly between two adjacent time stations. The summation used integral factor in EPSD, which constant coefficients are independent harmonically modulated excitation. obtained time-history analysis...
In our previous work, the concept of generalized attractive region in strategy investigation has been proposed. With this simple concept, a logical way to form strategies achieve high precision tasks with minimum sensory feedback was achieved. The successfully applied some robotic assembly, pushing and grasping systems. paper, conditions environment, which can regions, are systematically analyzed theory. Through simulation results, it shows that systems satisfy these therefore there regions...
In our previous work (Qiao, 2000), the concept of "generalized attractive region" in strategy investigation has been proposed. With this simple concept, a logical way to form strategies achieve high precision tasks with minimum sensory feedback was achieved.
