ANALYSIS ON THE VIBRATION OF NEEDLE BAR TAKE-UP MECHANISM IN HIGH-SPEED AND TWIN-NEEDLE HIGH SPEED LOCKSTITCHER BASED ON MULTI-BODY DYNAMICS
The needle bar mechanism in high-speed and Twin-needle High Speed Lockstitcher is one of the main reasons that cause vibration and noises. The needle bar is required to move reciprocating in vertical direction to stab fabric and wave back and forth in horizontal direction to push fabric. Then it is compound with take-up mechanism, which formats the multi-body system. The multi-body dynamics model of system is built. Its vibration response is researched by using ADMS which is a dynamic system simulation software. The impact on the basis amplitude and the fuselage amplitude, which is caused by vibration system parameters at different frequency, is analyzed. The research work provides theoretical basis for optimal design, vibration isolation design and noise reduction in Twin-needle High Speed Lockstitcher.
