中文摘要: |
为了在保证失重称的计量精度的前提下,提高失重称的计量速度,笔者将称重过程中的失重称简化成基本的力学模型,运用数学计算对称体的动态特性进行分析,研究了称体阻尼μ、称体的弹性特性k以及阻尼平衡时间tp等参数,并得出他们之间的关系式。通过研究提出:阻尼平衡时间tp是失重称动态性能的重要参数,他的大小直接关系到称重速度和精度。以此理论分析为前提,可对后续失重称的参数设计提供方法。 |

Under the premise of ensuring the measurement accuracy of loss in weight feeder, to increase the measurement speed of loss in weight feeder, this paper simplified the loss in weight feeder into a basic mechanical model, adopted the mathematical calculation to analyze the dynamic characteristics, studied the damping μ, elastic properties k, damping balance time tp and obtained the relationship between them. Through the research, it is put forward that damping balance time tp is an important parameter of loss in weight feeder, its value is directly related to the weighing speed and accuracy. And based on the theoretical analysis,the method can be used for the parameter design of loss in weight feeder. |
