The paper focuses on a method for assessing the dynamic loading of the frame of a special wheeled chassis when it moves on roads of various categories. Based on the developed finite element model of the frame, we obtained and analyzed full-size patterns of the stress-strain state of the frame and oscillograms of equivalent stresses in the most loaded zones of the frame.

The process of multi-wedge cross wedge rolling is an advanced precision technology for forming long shaft parts such as automobile semi-axes. Three-dimensional solid model and the finite element model of semi-axes on automobile and dies of its cross wedge rolling were established. The process of cross wedge rolling was simulated according to the actual dimension of semi-axes on automobile utilizing the finite element method (FEM)software ANSYS/LS-DYNA. The required force parameters for designing semi-axes mill are determined. The appropriate roller width was determined according to the length and diameter of semi-axes on automobile. The results have provided the basis for the design of specific structure of automobile semi-axes cross wedge rolling mill.

The research presented in this manuscript focuses on the development of an LS-DYNA finite element model to predict the dynamic shear strength of short riveted lap-spliced specimens. Using data collected from experimental testing at the U.S. Army Engineer Research and Development Center (ERDC), a finite element model was developed to replicate the behavior of A502 Grade short riveted connections under quasi-static loading. Subsequent analyses used published Cowper-Symonds constitutive model coefficients to replicate the behavior of these connections under dynamic loading. Computed results were then compared with available test data from ERDC. Given the challenges involved in creating physical models with riveted connections and the abundance of historical bridges constructed with rivets, the developed finite element analysis engineering solution can serve as a critical tool for researchers interested in predicting the response of short riveted connections to dynamic loading and those interested in developing strategies to mitigate against this loading.

The Que-Ti joint is the traditional beam–column connection in Tibetan heritage buildings and plays an important role in bearing and transferring load. The structure of the Que-Ti joint is very complicated, which makes it very difficult to build a refined solid model during the numerical simulation process. This means that a simplified model of the Que-Ti joint is required. In this article, we propose a finite-element model updating technique based on uniform design and apply this to the finite-element model updating of the Que-Ti joint. A simplified model of the joint was simulated using two uncertain parameters, and by constructing the uniform design matrix, the specific size of each component within the simplified model was then determined. The stress state of the simplified model was compared to the refined solid model, with results indicating that the stress and strain response of the simplified model had a small rate of error when compared with the refined solid model, which confirmed that the finite-element model updating based on the uniform design was effective and that the simplified model of the Que-Ti joint could be applied to the analysis of the structure as whole. A field measurement was also conducted to further verify the numerical simulation. This investigation provides essential information for the structural analysis of Tibetan heritage buildings.

In this paper the initial finite element model (IFEM) of the Jing Yue Yangtze River Highway Bridge was established and achieved the reasonable finished state of the bridge, which was the large-span, unequal height pylons and mixed beam cable-stayed bridge. The three-dimensional IFEM of the bridge accurately reflected its mechanical behavior under the static loading, and the structure physical parameters and stiffness of the IFEM didn’t need updating through the static loading test. The boundary condition parameters of the IFEM were updated through comparing the measured modal results of the dynamic loading test with the modal analysis results of the IFEM. The updated finite element model can truly reflect the dynamic characteristics of the bridge structure, and the model can be used as the benchmark finite element model, which can provide reliable calculation benchmark of the long term status assessment during the service stage.

Crankshaft is one of the important parts of reciprocating compressor. It takes a large reciprocating compressor crankshaft as the research object. First it establishes the three-dimensional solid model of the crankshaft by the software Pro/E. Then it contacts the Pro/E and ANSYS Workbench by the interface to establish the finite element model of the crankshaft. After taking the modal analysis and calculations of the crankshaft in the ANSYS Workbench module, it obtains the foundation for the design of the crankshaft structure.
