在多原动机驱动的机械系统（简称多机系统）中，常常要求它们能实现同步运行，为了达到这一目的，以往多数采用齿轮传动等进行强迫同步，这样会使系统变得相当复杂，而目前也有不少多机系统单一采用自同步、振动同步或控制同步原理使系统实现同步运行，但对不少多机系统，采用单一同步难以获得所要求的同步运行状态。本文提出根据具体情况和条件及合理性等要求，采用自同步、振动同步与控制同步的复合形式，实现所要求的同步运动。该项申请将通过理论分析、数值计算和试验研究,首先 对多机机械系统同步的深层次问题进行研究；在自同步方面将研究原动机特性与外载荷相互协调来实现系统的自同步，在振动同步方面将研究双质体非线性近共振的振动同步，在控制同步方面将研究无线智能遥控的的控制同步；在此基础上，研究以无线智能遥控的同步为基础的复合同步，并将研究结果应用于工程实际中。上述研究在理论上有重大意义和在工程应用上均有重要的实用价值。

In the mechanical system with multiple dirvers (may call it multi-motor system in simply), the sub-systems are required with synchronous angular velocity and required phases when they operate together. Foremerly, in order to relize sychronization the stiff drives, such as gear drives and so on are adopted to reach forced synchronization, so the complexity of their construction is increased. In present, self-synchronization, vibratory synchronization and controlled synchronization are used to realize synchronization of the multi-motor system, but somtimes it is very diffcult to obtain the required synchronous state. According to the requirement of the specific circumstance, condition and design rationality in engineering, several deep-level problems in synchronous theory and complex synchronization combined by self-synchroniztion, vibratory synchronization and controlled synchroniztion should be investigated by the analysis of the theory, numerical and experiment investigation. These deep-level problems are as follows: for the self-synchronization theory of multiple motors system the harmonious relationship between the driver's characteristcs and external lood property should be studied; for the vibratory synchronization in multiple motors system the synchronous theory of multiple exciters rotors system with nonlinearity and working at near-resunant states should be investigated and for the synchronization theory of multiple motors system the wireless and far-distance intelligent controll method also should be studeid. Based on these methods mentioned above, the complex synchronization combined by self-synchronization, vibratory synchronization and controlled synchronization should be analysed thoroughly. After that the research results will be applied in engineering. It can bring the huge economic and society benefits.
