| Abstract: | The dynamical model of GA735-190 rapier loom principal axis was set up.The bearing was simulated by element Combi214,the finite element model of the principal axis was set up in ANSYS platform.Considering the gyroscopic effect modal analysis of principal axis in effect of more load steps was done,then top 5 complex modal were caculated.Campbell chart and tracing lmage were drawed,and critical speed of principal axis of 300-2 000 r/min was caculated,which provide reference to dynamical analysis and speed control. |
