摘要
本文对曲柄连杆往复式切割器工作特性进行了分析,利用傅里叶级数将切割器周期激励分解为简谐收敛级数,以特征值为插值结点对傅里叶级数的待定系数进行了求解,并利用叠加原理求出切割器振动系统的稳态响应。
This paper analyzed the characteristics of the crank and connecting rod reciprocating cutter, decomposed the cutter periodic excitation into the harmonic convergenc series using the Fourier series, undetermined coefficients of Fourier series are solved with the eigenvalues for the interpolation nodes, and by using the principle of superposition to calculate the steady-state vibration response of system.
