Model of ultrasonic motor is the foundation of the design of ultrasonic motor's speed and position controller. A two-input and one-output dynamic Takagi-Sugeno model of ultrasonic motor driving system is worked out using fuzzy reasoning modeling method in this paper. Many fuzzy reasoning modeling methods are sensitive to the initial values and easy to fall into local minimum, and have a large amount of calculation. In order to overcome these defects, equalized universe method is used in this paper to get clusters centers and obtain fuzzy clustering membership functions, and then, the unknown parameters of the conclusions of fuzzy rules are identified using least-square method. Different experimental data that are tested with different operational conditions are used to examine the validity of the fuzzy model. Comparison between experimental data and calculated data of the model indicates that the model can well describe the nonlinear characteristics among the frequency, amplitude of driving voltage and rotating speed. The proposed fuzzy model can be used to analyze the performance of ultrasonic motor driving system, and also can be used to design the speed and position controller of ultrasonic motor.

The Relationship

This study aims to investigate the characteristics of adaptability to stratum for thrust system in tunneling machines in composite stratum. Initially, variation coefficient thrust model has been constructed on the basis of a mechanical model. By analyzing the variation coefficient thrust model, the variation coefficient surface can be discovered. Second, by analyzing the relationship between spaces of variation coefficient surface and adaptability to compound ground, the variation coefficient surface family which indicates the adaptive ability to stratum conditions for pushing system has been discovered. Eventually, applying variation coefficient adaptability model to the driving system of shield machine in engineering applications, adaptability for two layouts with the same number of hydraulic cylinders in thrust system has been discussed in detail through comparison of numerical analysis and simulation in ADAMS. The results could provide theoretical foundation and support for the design of an adaptability thrust system under composite stratum.

In order to investigate the material and lubrication of the moving parts of a space probe, a sliding frication tester was developed under vacuum and cryogenic environment. The tester includes the following four parts: driving system, loading system, measuring system and refrigerating system. A computer program was also developed to acquire and record the experimental data. Friction coefficients of component pairs of material GCr15-GCr15 were tested in different environments on the tester. The results show that in terms of the friction coefficient and life of the friction pair under vacuum and low temperature environment, the pairs with vacuum grease are far better than that without grease. The tester meets the design requirements.

Safety And Environment

Mechanized tunneling is characterized by high automation, efficiency, safety, and environment-friendly during tunnel construction progress. Studies to improve the force transmission performance of the thrust system playing an important role among all sub-systems in shield machine have been conducted recently. In this paper, a new nonequidistant arrangement with load-balancing-oriented ability has been proposed under complex ground. Firstly, the required mechanical functions are derived from the force transmission ellipse model. Secondly, the symmetrical uneven thrust system model has been set up to solve the mechanical functions. Then, all characteristics for the symmetrical shape driving system model have been investigated in detail. Finally, applying the solving model to the thrust system of a shield machine with a diameter 6.28 m, which has been used to construct some tunnels, the comparison of force transmission between the designed uneven thrust system and the even system manifests that the performance for nonuniform driving system is more uniform than the latter. The results also proved that nonequidistant thrust system with the better transmissibility in force can be preferred under some mixed ground.

A new hydraulic chassis of rice transplanter is designed based on the paddy machinery operation requirements. Driving system adopts single pump four-motor scheme, and the anti-slide valve group is used to prevent the slippage of the shunt-wound hydraulic motors. Hydraulic steering system adopts single-way stable diverter valve for ensuring its response in time. Then, hydraulic system and components parameters are designed and calculated. The driving resistance and average slip rate are measured in paddy field. The experimental data verifies the correctness of theoretical calculation. The designed hydraulic driving system and steering system are simulated in AMESim. The simulated data, including pressure, flow, and torque, basically conform to the design requirement. The results verify the feasibility and reliability of chassis hydraulic scheme. The proposed design scheme may be extended to other vehicles for improving chassis performance.
