This paper studies the force and deformation of the connecting channel in Ningbo rail transit construction, which firstly used the mechanical shield method. Steel-concrete composite structural segments are used in the T-joint of connecting channel. The cutting part of the segments are replaced by the concrete and fiberglass instead of reinforced concrete. Basing on a variety of three-dimensional design software and ABAQUS finite element analysis software, a refined finite element analysis model of the special segments is established. By considering the influence of curved joint bolts, the force analysis of the special segments under the structural state before and after construction is performed. According to the analysis and comparison of the deformation of the segments with and without the bolts, it is concluded that the steel-concrete segments can withstand the pressure of the soil before and after the construction. Suggestions for the safety of the design and construction of the segments are put forward.

The purpose of cogging in open-die press forging is to maximize the internal deformation for better structural homogeneity and centre-line consolidation in the core of the ingot. A three-dimensional thermo-viscoplastic finite element analysis is carried out for the non-isothermal cogging process in order to study the distribution of hydrostatic stresses, effective strains and temperature of the ingot and the die during the process. In the simulation, V-die and flat-die are employed for computation. A circular ingot of body weight 160 ton is subjected to cogging simulation and the effects of cogging parameters, such as die configuration, die width, temperature gradient, height reduction and draft design, are compared between two types of dies. Thus favourable working conditions are suggested for better and more desirable product quality.

It was incomplete and may have missed some dangerous working conditions to select several typical working conditions only in traditional strength analysis of hydraulic excavator. Therefore, the paper proposes a strategy that takes the working conditions when the load at each hinge of working device reaches largest into account. The working device of a 21t hydraulic excavator was analyzed with finite element analysis method when comparing these working conditions with the traditional typical ones. The results come out that the largest stress of boom, arm and bucket under these conditions increased respectively by 4.6%, 5.6% and 19.1% compared with the traditional most dangerous conditions. Consequently, in addition to the traditional typical conditions, it will be more safe and reliable to analyze the strength with the largest hinge loads conditions.
