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 this paper, aiming at the bonding spot welding process for heterogeneous metal plates with different strength and thickness, a finite element simulation model for bonding spot welding was established. By using simufact-welding simulation software, the effects of different thickness of adhesive layers on contact resistance, welding heat and welding residual stress of welding process were revealed. The results show that the contact resistance of bonding spot welding process is increased and the heat production of welding joint is increased due to the existence of adhesive layer. The equivalent residual stress of joint has the same change trend in both radial and axial directions, and the minimum value is obtained when the thickness of adhesive layer is 0.05mm.

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.

For the vibration of boom system which caused by luffing system of aerial platform folding-jib in working condition, the dynamic differential equation of the boom system is established by using the flexible multibody dynamics theory and the Lagrange equations in this article. By deriving and solving the dynamics differential equation, the dynamic analysis of each boom and the dynamic relationship between the cylinder pressure and flow are carried out. The results show that the vibration of the boom during lifting is due to the interaction between the extending motion and the flexible elastic vibration. In addition, it is necessary to consider the effect of the elastic deformation of each boom. This paper also provides theoretical foundation for deep research on the hydraulic control system to control the vibration of the boom.

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.
