In order to establish the electro-hydraulic proportional system model of the robotic excavator quickly and accurately, an identification algorithm based on recursive least squares algorithm with forgetting factor is proposed. The basic the mathematical model of the electro-hydraulic proportional system are analyzed. Based on the theoretical models, the transfer function of the control system is obtained by recursive least square identification method. The improved recursive least squares algorithm with forgetting factor method overcomes the contradiction between the steady-state accuracy and tracking ability of the fixed forgetting factor algorithm, and makes the identification process have both higher dynamic response and higher identification accuracy. The experimental results show that the identification results are credible, which lays a foundation for system design, control characteristic analysis and intelligent control algorithm research.

In this paper, taking the plug valve as the research object, the deformation coupling model between the set screw and the cock is established by analyzing the structure and the mechanics of the plug valve. A leakage identification algorithm for the plug valve's sealing surface is established by analyzing contact stress of the plug valve's sealing contact surfaces which are constructed by auto-correlation function. Taking plug valve F-2 ISO-STANDARD as the research object, the variation of contact stress of the sealing surfaces is numerically studied with change of the number of tightening cycles of the set screw in the installing process, and then the sealing performance of the plug valve is studied numerically. Results of numerical study show that with the increase of the number of tightening cycles of the set screw, the contact area of the sealing surfaces increases, while the area of the leakage path gradually decreases, and the maximum contact stress of sealing surfaces increases at the stage of the initial sealing with the increase of sealing surfaces' roughness. With the increase of the fluid pressure in the plug valve pipe, the minimum cycle number of tightening, cock compression force and the maximum contact stress of the sealing surface increase at the stage of the initial seal contact. This research provides a new method for the study and application of the plug valve sealing.

In order to alleviate the freight pressure of the terminal, improve the operational efficiency of the terminal, find out and cope with the adverse effects brought by various uncertain factors on berth and quay cranes allocation, a scenario-based stochastic programming model with uncertain arrival time and container handling volume is formulated. Based on the actual operations of the terminal, the relevant numerical experiments were designed, and they were solved by CPLEX. The experimental results showed that the proposed integrated optimization model is valid in dealing with uncertainties. Meanwhile, it is found that the greater the arrival time fluctuation or the container volume fluctuation, the greater the impact on the plan. And the impact of time fluctuation is greater than that of container volume fluctuation. The relevant study results have practical significance in guiding the integrated optimization of berth and quay cranes allocation under uncertainty.

The calculation method of maglev car-body strength has not been unified yet, and the calculation of strength refers mainly to standards of conventional wheel-rail technology, which cannot meet the requirement of maglev technology development. This paper aims mainly at Shanghai high-speed maglev, and refers to other standards to establish the car-body strength analysis and calculation system for Shanghai high-speed maglev. To be specific, normal load conditions and special load conditions are created by linear superposition and combination of single operation conditions. In order to analyze the car-body strength, relevant researches have been carried out in the field of maglev aerodynamics, vehicle system dynamics and finite element strength analysis. In the process of theoretical analysis, actual measurements and test verification have been added. Finally, car-body analysis conditions and load conditions have been created; the car-body strength has been checked; the car-body strength analysis process frame of high-speed maglev has been developed. The results show that the theoretical analysis results are in good agreement with the experimental results, and the working load of maglev vehicle is defined.

In order to accurately evaluate the vehicle shift quality, the response model of the shifting process to the complex random uman body is established. The random vector composed of the human body model parameters corresponds to the random human body, and the distribution of the human is represented by the probability density of the human body model parameters. The concept of stochastic receptor response spectrum was introduced from the seismic response spectrum. The stochastic receptor response spectrum of the evaluation index with the parameters of the human body model was calculated and simulated for the known shift process. Based on the random receptor response spectrum, the research on the acceleration and annoyance rate was introduced. The shift quality was evaluated from single index and multiple indicators. The evaluation results reflected the feelings of all possible people on the shifting process and the distribution of people. It has solved the problem that the previous shift quality evaluation can not evaluate the random human body's feelings about the shifting process. This study provides a theoretical basis for the quality evaluation of shifting machinery for mobile machinery.

To get the inverse solution of the manipulator efficiently, a new method combining Analytic Method and Genetic Algorithm is proposed. The simulation results obtained by the MATLAB software show that the optimal inverse kinematics solution of the manipulator can be obtained by this new method, and the convergence speed is better than that of the traditional Genetic Algorithm.

When a robotic excavator is controlled by a human operator, it must comply with the intention of the operator. Besides, it must meet the safety and operational quality of construction indicators. Coordinating the relationship between the active decision of the operator and the accurate control of the machine system is the key issue of this paper. Flexible virtual fixtures are proposed to control trajectory of the robotic excavator, the input signal of the restricted motion direction is weakened by introducing the flexibility coefficient kτ. In this way, a human-robot shared control system for the robotic excavator is built. Trajectories are designed to validate the performances of the flexible virtual fixtures, and experiments are performed on the trajectory control and motion visualization system which is built based on virtual instrument. The results show that the flexible virtual fixtures reduce the tracking errors and the operator can avoid the obstacle on the trajectory.

The multi-section telescopic boom is widely used in truck crane as its working boom. At present, the design of telescopic booms relies on experience and lacks the theory and method of custom design. The design difficulty of the telescopic boom is reasonably determined in the section parameters, which determines the performance and self-weight of the telescopic boom. Based on the similarity theory, this paper uses the dimensional analysis method to derive the similarity criterion of the telescopic boom model and the ratio of similitude between the design model and the prototype physical quantity. Considering the actual processing rationality requirements, the equivalent moment of the custom model's section moment of inertia is calculated and the model section size parameters are determined according to the section design law. Finally, a cross-shaped parameter of a 50-ton telescopic boom model was custom designed with a hexagonal section telescopic boom of a 25-ton truck crane as a similar prototype. The results show that the custom model and the existing 50 tons of products have similar performance in terms of strength, stiffness and stability, which provides a feasible method for the customized and serial design of the telescopic boom of the truck crane.
