In the last issue of《Dimensional classroom》Li，Xiaowei takes you to understand the working principle and maintenance method of the pneumatic cutter head extractor of Wittgen milling machine.，From the current period《Dimensional classroom》Start，Xiaowei will bring a series of videos explaining vibration compaction technology to his fans.，The first phase will start with the working principle of vibratory compaction technology.，Through this series of videos,，What parameters are believed to be important to the Uyghur fans in similar compaction processes?、How does the setting of these parameters affect the construction effect?、We will have a deeper understanding of which performance parameters are critical in choosing the right roller.。As the saying goes, know what it is and know why it is.，Click on the video link to see the training teacher explain it to you.。

From the birth of compaction machinery，Especially the appearance of vibratory roller.，How to improve the compaction quality and operation efficiency has always been the main research direction.，An effective compaction process can solve this problem.。

The traditional vibratory roller usually has a vibrator with circular motion inside the steel wheel.，The vibrator makes the drum vibrate by rotating at high speed.，Transmitting a vertical downward force to the compacted material，O as to achieve the compaction effect.。Under the action of vibration force，A series of pressures generated by the machine are transmitted to the material being pressed.，Thereby reducing the friction force between the pressed material particles.、Reduction of air between aggregates，Achieve the purpose of compaction。The exciting force is one of the important indexes to measure the compaction ability of a road roller.，Low frequency and large amplitude are suitable for thick layers and compacted materials with small bearing capacity.；High frequency and small amplitude are more suitable for surface layering。For more information，Please check the expert explanation for a detailed understanding.。

《Dimensional classroom》It is a video column in which experts from Wittgen China Technology and Training Center give lectures on equipment operation and precautions.，Launch on a regular basis，I hope you will continue to pay attention.。In addition，If you have any questions you want to know, you can also send us a bullet screen or leave a message.。
