Free vibration of a sagged cable with attached discrete elements
《Applied Mathematics and Mechanics(English Edition)》2019年第5期631-648,共18页W.PAKOS 
An algorithm is presented to analyze the free vibration in a system composed of a cable with discrete elements, e.g., a concentrated mass, a translational spring, and a harmonic oscillator. The vibrations in the cable...
