In order to meet the requirements of high precision and rigidity of the two-dimensional turntable, it is necessary to carry out the structural design and position accuracy analysis of the two-dimensional turntable. The study found that the structure of the turntable, the resistance torque, the shaft structure, and the selection and design of the motor and sensor are all key factors affecting the performance of the two-dimensional turntable. In this paper, a method for structural design and simulation of a two-dimensional space turntable is proposed. In the process of structural design, these key factors are analyzed in detail, and the statics, modal and dynamic simulation analysis of the two-dimensional turntable are carried out using ANSYS Workbench software. Through simulation analysis, various indicators of the turntable are checked. Finally, it is concluded that the simulation results fully meet the requirements of the design indicators, which verifies the rationality of the design method and provides a strong basis for the structural design of the two-dimensional space turntable.

Augmented reality (AR) technology has been a rapidly developing research hotspot in the past ten years. AR combines computer-generated virtual scenes with the real world to achieve sensory enhancements beyond reality. As the middleware between the operating system layer and the application layer, the AR engine is a platform-based underlying technology and the cornerstone of building an augmented reality ecosystem. In this paper, a new AR engine architecture is proposed, and the core modules such as architecture composition, data management, algorithm integration, and multi-platform support interfaces are described in detail. Also, Nanhu AR engine (NHAR) is developed based on the new architecture. And an application is developed using NHAR to test marker-based tracking and marker-less tracking function of the developed engine.

This article is concerned with the robust control of a class of uncertain systems with linear nominal part and perturbations which are of two kinds: matched and unmatched. A specific variant of Integral Sliding Mode Control (iSMC) is employed to systematically derive robust controllers for the specific class of systems for both stabilization and setpoint tracking objectives. The linear part of the composite controller employs mature linear control tools, while its nonlinear part is a nonlinear state feedback with “unit control” structure depending on the sliding surface and the uncertainty bounds. It is shown that an optimal selection of the sliding surface and the consequent selection of the nonlinear gain multiplying the “unit control” action, guarantee that sliding mode is achieved after a finite time interval despite the presence of unmatched perturbation. After entering sliding mode, the matched perturbations are fully rejected while the unmatched ones are non amplified. The numerical examples demonstrate the proposed methodologies on a single input nominally unstable plant.

With the deepening of the development and application of Internet of Things technology in the medical field, product design and interaction design have developed greatly. The market demand of the medical industry continues to expand, and the use environment of medical equipment has expanded from hospitals to families, and users' requirements for medical rehabilitation equipment have also increased, forming higher emotional needs. The Kano evaluation method was used to obtain the needs of autistic patients for transcranial electromagnetic therapy equipment, and the questionnaire survey screened and sorted out the perceptual vocabulary, established a sample bank, selected typical samples, and analyzed the semantic evaluation method to obtain the data to vaguely interpret the patient's perceptual intention. There are different opinions between doctors and patients on design requirements, many differences in functional requirements, and similar opinions on modeling and interaction requirements. Through the Kano model to investigate the needs of both doctors and patients and perceptual engineering, the patient's perceptual needs are transformed into the design elements of the product into usable data, which provides a method for extracting the design elements and transforming them into applications, and realizes the appearance of transcranial electromagnetic therapy device for optimal design.

To study the distribution law of the internal flow field and temperature field of permanent magnet synchronous motor (PMSM) for special vehicles, this paper takes a PMSM with a rated power of 300KW as an example, which adopts the cooling structure combined with the spiral channel of the housing and the fan of the rotating shaft. Based on computational fluid dynamics (CFD) and heat transfer theory, a three-dimensional full-domain simulation model of the motor was established. The finite volume method was used for numerical calculation and analysis of the motor's flow field and temperature field, and the fluid flow characteristics of the spiral channel and the air in the motor and the temperature distribution characteristics of each component were analyzed. The wind resistance moment of the rotor surface was calculated based on CFD, and the wind friction loss was obtained according to the relationship between the wind resistance moment and the wind friction loss. Finally, experimental tests were conducted on the prototype, and the experimental results data were compared with CFD simulation calculation results to further calibrate the PMSM flow field and temperature field simulation calculation model, which provides some reference and practical engineering value for wind friction loss calculation, cooling system design and temperature field simulation calculation of PMSM for special vehicles.
