【摘要】 针对液压悬置复杂的动态特性,运用流体动力学理论及液压原理,建立了某轿车动力总成液压悬置的非线性数学模型,提出了模拟液压悬置动态特性的一种数值分析方法,并对目标液压悬置的动态特性进行了多工况仿真实验对比。研究结果表明所建模型是正确的、实用的,而且其通用性较强,能为下一步更精确的汽车动力总成悬置系统匹配选型、优化分析、隔振特性研究提供基础。更多还原

【Abstract】 Aimed at the complicated dynamic characteristics of hydraulic mount,an automobile powertrain hydraulic mount’s non-linear mathematics model was created with the hydrodynamics theory and hydraulic principle.A numerical analysis method for simulating the dynamic characteristics of hydraulic mount was put out,and the characteristics was studied by contrasting simulations and experiments under a few working conditions.The results show the model is correct,practical and universal,which can provide a foundation for more precise automobile powertrain mount system matching,optimizing analysis and vibration isolating research.更多还原
