Studies on Dynamic Characteristics of Main Shaft for TM Electronic Jacquard Machine

摘要

The integrated transfer matrix method is brought forward on the basis of transfer matrix method and integrated transfer matrix theory is applied to the analysis on the dynamic characteristics of the main shaft for TM electronic jacquard machine.Through analysis on the dynamic model of the main shaft, the critical speed and the vibrating model of the main shaft for the high-speed electronic jacquard machine are derived theoretically and calculated and the first several order natural frequencies and the corresponding main vibration models of the main shaft are found.It is shown from the comparative analysis of the calculation results that the integrated transfer matrix method with higher computation accuracy can keep the characteristics of transfer matrix method such as simple programming, small computation amount and fast operation speed.This analysis and calculation method has higher reference value to the design of the main shaft of other types of jacquard machine and the dynamic analysis of similar complex rotor system.
