The Research on Sensor Optimal Layout on Detection Device for Automobile Seat Horizontal Drive Mechanism
No full textThe type of the sensor and the optimal placement of the installation location of the sensor are important factors in vibration signal acquisition on automobile seat horizontal drive mechanism (HDM) for quality grading. According to the characteristics of HDM, the actual installation condition and the attenuation characteristic of the vibration signal transmission, the type of sensor was selected reasonably. By means of finite element analysis method, the best placement of the sensors to mount on the fixture was analyzed aim to maximize the information reflecting the fault and be sensitivity to the direction of the vibration. The finite element simulation and experimental results show that the acceleration sensor can effectively detect the fault characteristic signal, which provides a basis for further quality grading for HDM

A New Stream of Spiritual Literature: Bei Cun’s The Baptizing River
No full textThis essay traces the emergence of new categories of “spiritual writing” in Chinese literature, before offering an interpretation of Bei Cun’s 1992 novel The Baptizing River (Shixi de he 施洗的河) as an exemplar. Bei Cun’s first novel as a “Christian author” attracted much critical attention, given the contrast with the author’s prior works and its message of spiritual salvation at a time of political change and metaphysical searching. A psychosocial biography of its anti-hero Liu Lang, set in wartime China, the novel charts the protagonist’s criminal livelihood, descent into moral depravity, and gradual questioning of life and purpose. This essay foregrounds the structure of the novel and explores how narrative form and theological meaning interact. To do this, it traces the course of the river journeys that mark the different stages of Liu Lang’s life and which culminate in his unorthodox baptismal rebirth
Torsional Vibration of a Shafting System under Electrical Disturbances
No full textTorsional vibration responses of a nonlinear shafting system are studied by a modified Riccati torsional transfer matrix combining with the Newmark-β method. Firstly, the system is modeled as a chain consisting of an elastic spring with concentrated mass points, from which a multi-segment lumped mass model is established. Secondly, accumulated errors are eliminated from the eigenfrequencies and responses of the system's torsional vibration by this newly developed procedure. The incremental transfer matrix method, combining the modified Riccati torsional transfer matrix with Newmark-β method, is further applied to solve the dynamical equations for the torsional vibration of the nonlinear shafting system. Lastly, the shafting system of a turbine-generator is employed as an illustrating example, and simulation analysis has been performed on the transient responses of the shaft's torsional vibrations during typical power network disturbances, such as three-phase short circuit, two-phase short circuit and asynchronous juxtaposition. The results validate the present method and are instructive for the design of a turbo-generator shaft
A novel laser ultrasonic thickness measurement method for metal plate based on spectral analysis
No full textTheoretical Insights into Dual-Atomic Catalysts for Electrochemical CO<sub>2</sub> Reduction
No full textElectrochemical reduction of carbon dioxide into value-added
products
is expected to be a promising approach to mitigate climate and energy
crises. However, the inert nature of CO2 molecules and
the lack of effective electrocatalysts pose fundamental challenges
that hinder electrochemical CO2 reduction. In this work,
density functional theory was employed to explore a series of dual-atom
catalysts (DACs) supported on four-type nitrogen-doped graphene for
the CO2 reduction reaction (CO2RR). Based on
the correlation between the adsorption free energies of the reaction
intermediates, we find that the scaling relations in the multi-intermediate
reactions still persist, which distinguishes them from previous studies.
In addition, we construct a universal descriptor based on the intrinsic
properties of catalysts, which can well assess the catalytic activity
of different transition metal dual-atoms on different supports for
the CO2RR. Finally, the constant potential calculation
reveals that the adsorption of *CO2– exhibits
insensitivity toward changes in applied potential for CoCo-3A DACs.
The thermochemical step was found to be the limiting step at a low
electrode potential. This research elucidates the underlying principles
of reaction mechanisms and simultaneously furnishes a systematic framework
for expedited exploration of proficient catalysts
