工程中的振动同步与控制同步

章节摘录

插图：There is a variety of plane motion self synchronous vibrating machinesbeing widely used in industry for material feeding, conveying, screening,cooling, drying, forming and casting, such as the self synchronous vibratingfeeder, the self synchronous vibrating conveyor,  the self synchronousvibrating cooler, the self synchronous vibrating probability screen, the selfsynchronous vibrating dryer, the self synchronous vibrating sand-droppingmachine, the self synchronous straight line vibrating screen,  the selfsynchronous cold and the hot ore vibrating screen, etc. These machines havethe following advantages.（1）The drive system is much simpler than a forced synchronous systemwith a mechanical transmission chain due to that there is not a gearbox in aself synchronous system.（2）Easy for lubrication, maintenance and service without gearboxes.（3）The amplitude of resonant vibration can be significantly reduced forsome of self synchronous vibrating machines during the starting or thestopping process.（4）Most self synchronous vibrating machines used in industry aredirectly driven by exciting motors, which make the drive systems evensimpler and easily installed, and offer a significant cost savings.（5）Easy to realize a seriation, generalization and standardization.

前言

A synchronous phenomenon is a form of movement naturally existing innature as well as in human society and production.  Most synchronousphenomena are naturally formed during the evolution process of the naturalworld and the human society. However, in engineering and technology, it isoften created artificially to satisfy people's needs.  In most cases, thesynchronous phenomena are beneficial to human beings, but are harmful inother cases.  For  example,  synchronous  satellites  in  space  orbit  insynchronization about the earth. Another example of the synchronizationphenomena is in radiobroadcast, one of the most common ways to transmitinformation in human lives. In order to receive the expected sounds fromradio stations, the receiving frequency of the radios must match the sendingfrequency from the radio stations, which is so-called sending-receivingsynchronization. But in other circumstances, the synchronization phenomenamay be unwanted as they may be hazardous and harmful.  For example,soldiers are forbidden from marching synchronously in a group on a wirebridge, because the resonant forces produced by the synchronized runningmay cause a disaster.The synchronous phenomena and their issues can be found anywhere inthe natural world and fields of engineering and technology.
