For efficient modeling of engine (or powertrain) supported by non-linear elastic mounts, a special methodology has been elaborated. Based on it, software tool has been developed to analyze the motion of rigid body and elastic mounts, which comprises of three modules:
• Non-linear static analysis;
• Modal analysis (undamped and damped);
• Forced response (in frequency domain).
Application example of a large V12 marine engine illustrates the suggested workflow.
The results are verified against other software tools and validated by measurements.
