AB  - This study delves deeply into the dynamic performance of modular dobby systems used in the textile industry,
underscoring the pivotal role of assembly errors in high-speed environments. It uncovers that such errors significantly
escalate the vibration of follower components at elevated speeds, with the impact becoming more pronounced as speed
increases. Whether employing interference or clearance fits, discrepancies between the cam and roller substantially
influence the mechanism’s dynamic behaviour. Although interference fits can partially mitigate vibration, they may
intensify during high-speed operations. In contrast, clearance fits not only heighten vibration but also reduce contact
stiffness, thereby affecting the mechanism’s precision and longevity. Drawing from these findings, the study advocates
for the preferential use of ideal or interference fits during design and assembly to minimise or eliminate the need for
clearance fits. Ideal fits are conducive to maintaining low vibration levels, while interference fits bolster contact stiffness
and diminish vibration. Additionally, maintaining optimal lubrication is imperative for curbing friction, wear, and vibration,
thereby directly enhancing system performance and stability. In conclusion, a comprehensive grasp of how assembly
errors affect modular dobby machines is of paramount theoretical and practical significance, facilitating design
optimisation and bolstering the mechanism’s performance and reliability.
