Direct-Inverse Fourier Transformation Technique for Responses of Non-Linear Torsional Vibration of Diesel Shafting

本文提出了一种用Fourier正逆变换对非线性扭振系统进行数值求解的方法,并用派生响应的新概念分析与解释非线性振动响应的机理.文中介绍了该方法的理论基础,并用实例作了计算与分析,证明运用此法是可行的和成功的.

Direct-inverse Fourier transformation for numerical solutions of nonlinear torsional vibration system were proposed in this paper. A new concept of derivative responses was introduced to explain the fundamental principle of responses of non-linear vibration. A practical calculation example was given and satisfactory results were obtained.
