| 摘 要： | 能量解耦率直接影响到动力总成悬置系统的隔振性能。先以悬置位置参数和刚度参数为设计变量对系统的能量解耦率进行了优化设计,然后分析了悬置元件安装位置约束范围对系统优化解耦率的影响。结果表明:优化设计提高了系统能量解耦率,可以通过加大悬置位置约束范围来获得更高的解耦率,而系统的紧凑性损失不大。

| Abstract: | The energy decoupling has directly effects on the vibration isolation of the powertrain mounting system.Taking mounting position and stiffness as parameters,the energy decoupling was optimized.The impact of constrained range of mounting position on optimized system’s energy decoupling was analyzed.The result indicates that the decoupling of main vibration direction is improved.It also shows that a higher system’s energy decoupling can be obtained by increasing the constrained range of mounting position at a less price of vehicle’s compactness. |
