Abstract:
The dynamics model of the transmission system of the internal grinder is established on the bases of Riccati transfer matrix. The dynamic characteristics of the internal grinder are obtained by analyzing the relationship between dynamic modal flexibility and modal flexibility, which is used to find out the dangerous model of the transmission system and its weak areas. Then design parameters of weak areas are modified, the new one from the old structure is put forward, and the dynamic characteristics of new structure are forecast through the calculations of the modal flexibility and elasticity distribution rate. This method is applied successfully in designing the transmission system of the internal grinder.
基于Riccati传递矩阵法建立了内圆磨床传动系统的动力学模型.由模态柔度和弹性分布率的计算, 分析了原内圆磨床传动系统的动态特性, 应用动柔度与模态柔度的关系, 找出传动系统的危险模态及其该模态上的薄弱环节, 提出了结构修改方案, 避免了参数调整的盲目性, 并预测了其动态性能, 在内圆磨床传动系统设计中得到了有效的应用.
