在波纹管的应用中,需正确了解其自振频率,特别是当与其连接的构件存在振动情况时,尤其要正确计算其自振频率。 对于均匀波形的通常情况、已有频率计算公式[1];近些年来,已有文章报导对其进行的较为深入的研究情况[2]。对于非均匀波形的特殊情况,已提出了自振频率计算的离散模型[3]。 本文提出了波纹管轴向自报频率计算的连续体模型。这一模型既适用于均匀波形情况,也适用于非均匀波形、有附加质量等特殊情况,并给出了自振频率求解所需方程。为设计计算提供了方便。
In the application of corrugated pipe, it is necessary to correctly understand its natural frequency, especially when connected with the components there is vibration, in particular, to correctly calculate the natural frequency. In the usual case of uniform waveforms, there is a formula for frequency calculation [1]. In recent years, more studies have been reported on it [2]. For the special cases of non-uniform waveforms, a discrete model of natural frequency calculation has been proposed [3]. In this paper, a continuum model for calculating the axial self-reported frequency of bellows is presented. This model is suitable for both uniform waveforms and non-uniform waveforms, with additional qualities and other special cases. The equations needed to solve natural frequency are given. For the design and calculation provides a convenient.
