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.

Using Data

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.

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.
