振动碗式给料系统的建模可分为两部分，即模拟（a）碗式给料机结构振动和（B）在给料条件下部件的行为。本文用集中参数法处理前一个问题，即用三组柔性板簧将刚性碗和刚性底座隔开。从该模型计算的固有频率和振型进行了比较与实验模态分析的零件送料机。该模型可以很容易地实现在数字计算机上使用标准的NAG例程的矩阵操作和计算的特征值和特征向量。
The modelling of vibratory bowl feed systems can be considered in two parts, namely the simulation of (a) the bowl feeder structure vibrations and (b) the behaviour of the components under feed conditions. This paper deals with the former problem using a lumped parameter approach, whereby a rigid bowl and rigid base are separated by three banks of flexible leaf springs. Natural frequencies and mode shapes computed from the model are compared with those obtained by experimental modal analysis of a parts feeder. The model can be easily implemented on a digital computer using standard NAG routines for matrix manipulation and computation of eigenvalues and eigenvectors.
