Acoustic Analysis in Abaqus声学仿真
Based on a strategic co-operation with the company ABAQUS, AVL has implemented a seamless acoustic analysis, which is outlined in this paper. The complete workflow is demonstrated on an inline 4 cylinder gasoline engine and compared with the traditional MSC.Nastran-oriented approach. This new ...

Advanced linear dynamics and substructuring capabilities in Abaqus with applications in noise and vibration analysis Linear dynamic simulations with Abaqus can capture nonlinear effects of pre-loading, unsymmetric effects (for example, from rolling tiers), acoustic-structural coupling, and frequency-dependent...
Although finite element software like ANSYS, ABAQUS and COMSOL has been well developed to analyze these complex shells, FEM has obvious disadvantages in computational efficiency due to the complexity involved in modeling and solution. Furthermore, to meet the requirements of convergence, a huge number...
With the increase in the analysis frequency, the mass of added water is characterized by first decreasing rapidly and then decreasing gradually and smoothly. The contained water between the double hulls is distributed to the pressure hull and the light shell based on the ratio of the impedances ...
The paper is organized as follows: Section 1 provides an introduction to the study's focus. Section2presents the geometry, vibration damping performance, and coupling analysis of the PABH-DVA. In Section3, the mechanism behind the enhanced damping effect is discussed. Section4examines the influenc...
