Hilbert-Huang Transform (HHT) causes modal aliasing and false modes in identifying modal frequencies of structures, thus a power spectrum modal frequency identification method based on Empirical Mode Decomposition (EMD) is proposed. The paper chooses quayside container crane (QCC) as the object of research. Firstly, the finite element model of QCC is established to identify the modal frequencies by modal analysis. Secondly, EMD is applied to the monitoring signals of QCC. According to the principle of correlation, the effective Intrinsic Mode Function (IMF) components are screened to identify the modal frequencies by power spectrum. The experimental results show that the method of frequency identification is close to the results of finite element frequency identification, and can effectively eliminate the false modes, improving the efficiency of frequency identification. The results of identification are more intuitive.

In this paper, hypermesh software and ansys software are used to carry out finite element modeling and structural strength analysis of the longitudinal beam of the maglev vehicle. According to the actual situation, the load of eight working conditions is applied to the longitudinal beam, and the strength under each load is calculated. The calculation results show that the main part of the longitudinal beam meets the static strength requirement, and the stress is less than the material yield strength limit. However, the stress concentration is likely to occur at the bolt hole of the push rod bracket base. The problem of stress concentration can be improved by increasing the thickness of the plate and changing material.

In order to meet the requirements of the water purification equipment with floating body and improve its operation stability and comprehensive performance, the design and research of floating body and height self-adjusting mechanism are carried out, and the comprehensive operation characteristics of spherical and regular tetrahedral floating body are compared and analyzed. Based on the simulation study, an analysis model of floating body regulating mechanism is established, and its dynamic performance optimization analysis based on parametric adjustment is carried out. The position of key hinge points of the mechanism and the theoretical basis of self-adjusting cylinder selection are determined. The results show that the mass of spherical floating body is about 30% less than that of tetrahedron with the same buoyancy.

In this paper, a hydraulic flexible joint for legged robots is presented to meet the requirements of flexible control and variable stiffness in varies of conditions. A proportional flow valve for closed-loop position control and an inverse proportional pressure valve for output force regulation are combined in series in the hydraulic joint, and force-position hybrid control is adopted for this joint. The detailed design and control method are proposed and analyzed. The experiment results show that the hydraulic flexible joint not only can realize the high accurate position control, but also can proportionally adjust the stiffness in a wide range. When the force and displacement constraints are applied, the performance of hydraulic flexible joint is good under the force-position hybrid control.

As a major machine parts of tunnel boring machine(TBM), the segment erector were payed attention. To make supporting beam of segment erector have sufficient strength and stiffness, the paper established in a three-dimensional model of segment erector using SOLIDWORKS. The model were imported in ANSYS, and simulated in the two extreme working conditions. The stress and displacement contours were obtained, and it is shown that the stress and displacement are more than criterion. After the height of supporting beam are increased by 500mm, and the thickness of supporting beam are increased by 10mm, stress is reduced by 30%, the displacement is reduced by 21%. The optimized design goal was gained.

To design container cranes with reliable performance levels under multiple seismic hazards, an approach is developed for performance-based design optimization (PBDO) of container cranes. First a simplified planar finite element model is built for container cranes. In order to mitigate the seismic responses, buckling restrained braces (BRB), instead of ordinary braces, are used in the model. Two performance criteria are considered and the deformations of structural elements are selected to define the performance criteria. The pattern search method is employed to efficiently solve the optimization task. The result indicates that the structural weight of container cranes can be remarkably reduced while satisfying multiple performance requirements. Conclusion can be drawn that the proposed approach is an efficient method for PBDO of container cranes.
