Abstract:

A general dynamic balancing method was proposed for high speed mechanism based on vibration response. Unlike the traditional approaches, this method aimed at reducing vibration response directly. By analyzing the vibration response in frequency domain, and forming generalized exciting load vector and generalized vibrational characteristic matrix, a dynamic balancing optimization model was established, where the mass parameter of mechanism and the vibration response of ground were employed as its design variable and objective function, respectively.

Key words: dynamic balancing, vibration response, generalized exciting load vector, generalized vibrational characteristic matrix

摘要：

针对一般高速机构的动平衡问题，提出了一种普遍适用的基于振动响应的动平衡优化方法。与传统动平衡方法不同，该方法直接以降低振动响应为目标。通过频域内的振动响应分析，构造了系统的广义激振载荷向量和广义振动特征矩阵，建立了一个以构件质量参数为设计参数、以机座振动响应为目标函数的动平衡优化模型。
