针对同步带传动印刷机启动中的扭振问题，建立了传动带系统的数学模型，通过分析模型找出引起扭振的主要原因，且搭建同步带传动试验平台对扭振现象进行研究。采用五阶段S曲线加减速方法对电机启动输入信号进行规划来抑制系统扭振，并提出运用粒子群优化算法，解决了规划五阶段S曲线参数选取困难的问题。通过仿真试验和试验平台验证可行性，证明了优化后的五阶段S曲线输入信号避开了谐振频率，在较小的牺牲同步带系统动态性能的同时大幅度抑制扭振。

To solve the problem of the torsional vibration that the startup of synchronous belt transmission printers, a mathematical model of the belt system was established, the main cause of torsional vibration through the analysis of model was found, and the phenomenon of torsional vibration through the synchronous belt transmission test platform that has been established was studied. To suppress the system torsional vibration, five-phase S-curve acceleration and deceleration method was used to plan input signals in the motor starting, and the difficult problem of S-curve parameters selection was solved by using of particle swarm optimization algorithm. The feasibility of the algorithm were verified through the simulation test and the test platform. Results show that the optimized S-curve avoids resonance frequency of the input signal that is close to resonant frequency, and losses the dynamic performance of synchronous belt system, meanwhile suppress torsional vibration significantly.
