Dynamic Performances

The comprehensive performance test of motorized spindle will contribute to improve the machining quality of machine tool. But existing standards for testing the performance of motorized spindle are limited to test its partial static and dynamic performances. Meantime, most of the researches only focus on the vibration, thermal deformation, and rotary accuracy of motorized spindle. Consequently, how to accurately and comprehensively test the performance of motorized spindle is the key problem. For solving this problem, a comprehensive testing technology is presented in this article. In detail, some principles for establishing a test index system are proposed. And, by synthetically and systematically analyzing the process of structural design, manufacturing and assembly, use, and service, an index system for characterizing the comprehensive performance of motorized spindle is built. Then, some operational test methods are provided to evaluate the selected indexes. Finally, the proposed technology is taken to test a motorized spindle. In brief, the proposed technology will make the performance test of motorized spindle more comprehensive and operational and can provide support for improving the comprehensive performance of the motorized spindle.

Corrosion Defects

Small-diameter tubes that are widely used in petroleum industries and power plants experience corrosion during long-term services. In this paper, a compact inserted guided-wave EMAT with a pulsed electromagnet is proposed for small-diameter tube inspection. The proposed transducer is noncontact, compact with high signal-to-noise ratio and unattractive to ferromagnetic tubes. The proposed EMAT is designed with coils-only configuration, which consists of a pulsed electromagnet and a meander pulser/receiver coil. Both the numerical simulation and experimental results validate its feasibility on generating and receiving L(0,2) mode guided wave. The parameters for driving the proposed EMAT are optimized by performance testing. Finally, feasibility on quantification evaluation for corrosion defects was verified by experiments.

The inheritance and innovation of ancient architecture decoration art is an important way for the development of the construction industry. The data process of traditional ancient architecture decoration art is relatively backward, which leads to the obvious distortion of the digitalization of ancient architecture decoration art. In order to improve the digital effect of ancient architecture decoration art, based on neural network, this paper combines the image features to construct a neural network-based ancient architecture decoration art data system model, and graphically expresses the static construction mode and dynamic construction process of the architecture group. Based on this, three-dimensional model reconstruction and scene simulation experiments of architecture groups are realized. In order to verify the performance effect of the system proposed in this paper, it is verified through simulation and performance testing, and data visualization is performed through statistical methods. The result of the study shows that the digitalization effect of the ancient architecture decoration art proposed in this paper is good.
