摘要

为了对非线性弹性支架支撑的发动机(或动力系统)进行高效建模，提出了一种特殊的建模方法。在此基础上，开发了刚体和弹性支架运动分析软件工具，包括三个模块:•非线性静力分析;•模态分析(无阻尼和阻尼);•强制响应(在频域)。某大型V12船用发动机的应用实例说明了所建议的工作流程。结果与其他软件工具进行了验证，并通过测量进行了验证。

Powertrain Resilient Mounting Design Analysis

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.
