Summary.A detailed contact analysis of a large connecting rod was performed to evaluate the fretting risk in the big end. Simulation was carried out in Abaqus considering all relevant boundary conditions, such as assembly loads, housing machining and dynamics from a flexible multibody simulation with elastohydrodynamic bearings. Being one of the most important variables, the local coefficient of friction (COF) and its evolution is calculated during the solution by using a subroutine in Abaqus. The model is validated by strain gauge measurements in a running engine. The resulted friction coefficient distribution matches well with the findings from a laboratory engine. The described methodology increases the accuracy of the fretting damage prediction by using a more realistic friction coefficient definition.

“…The application uses substructures for the rest of the main components to generate a complete generator set model from a user-defined configuration. These substructures can be easily generated from virtual engine models used in multi body dynamic simulations [2,7,8] and added to the database the application uses. This database also contains response analysis Abaqus input files for different engine types.…”

Summary. The natural frequency and vibration response calculation process of a generator set was automatized so that it can be used in a generator set common base frame concept design. The implementation of automatization was to be done so that no profound knowledge about the finite element method is needed to execute calculations and that computation times are short. Substructuring is used for certain parts of the generator set model to reduce the computation times for more a efficient concept design process. The common base frame concept design is implemented to the process by using a design tool in which the finite element model generation from parametric geometry is automatized. Generator set finite element model generation, natural frequency and vibration response calculations and post-processing of analysis results were implemented by developing a calculation tool for this purpose. The calculation tool is an independent application that uses Abaqus simulation software to execute analyses.

“…Condensation, see Figure 2, is done by running Abaqus analysis using preferably the Craig-Chang or Craig-Bampton sub-structuring methods [7]. The condensation method is explained more detail in [6]. The MBD analysis is done with a suitable software package.…”

“…To ensure the reliable function of this critical component, multiple types of analysis are carried out. The most common types are the static concept analysis, the dynamics stress and fatigue analysis and the closely related bearing [2], connecting rod [6] and fretting analysis [9]. The virtual engine crankshaft simulation methodology is presented in [3].…”
