【正文】 draulic servo control system integration and transformation of the traditional mechanical engineering products, Computeraided design and puteraided manufacturing and puteraided management of construction machinery and equipment manufacturing, IT work technology equipment, construction machinery sales and information transfer systems, thus enabling people to see a brand new construction machinery industry. New construction machinery products in the efficiency and operational quality, environmental protection, performance and automation are many areas due to the past. and toward the further robotic and intelligent direction. operating principles of Innovation : groundbreaking new law with the highfrequency vibration With scientific and technological research in the development, engineering machinery operating theory is constantly innovating. Operating mechanical engineering principles, including the cutting of earth, broken ground on the screen geotextile material, mixed with heating, right mixture of paving, leveling and paction, etc.. These operations Jimmy initially bionics and Newtonian mechanicsbased, Modern science and the development of engineering machinery operating principle of laying the foundation for innovation. For example, mechanical vibration and pulse jet, the photoelectric effect and thermal physics, the application of mechanical engineering to save resources and improve the quality of construction improve production efficiency, reliability and driving fort and a degree of automation to create conditions. Excavators, bulldozers, loaders, and other earthmoving machinery cutting groundbreaking project, we had no struggle milling, highfrequency vibration, Liquid gas jet method and porous ground breaking law. Groundbreaking use of the new operating principle of transformation to a bucket, can loosen the soil excavation for the highintensity rock, Under normal circumstances can reduce the unit cost of earthwork and improve production efficiency, and the soil near the building when substitute 邵陽學院畢業(yè)設計（論文） 3 boredblasting method. Vibratory Roller is a mechanical vibration and have reached a sluggish vibration to operational effectiveness of the most powerful note. Highfrequency vibration paction technology is the application of modern dynamics in the mechanical engineering important research results, In vibratory roller simultaneously with the application of vibration isolation theory. 90s of the 20th century, there have been a level of vibration (vibration) and vertical vibration directional vibration paction method, and an AMvibration and different from the harmonic vibration of chaotic vibration vibratory paction operating principle, and the formation of the corresponding series of vibratory roller. Impact Roller broke the existing traditional cylindrical roller structure, Use 35 edge with the pressure roller polygon dragged by a tractor, 23 times per second in order to impact on the ground. This has dramatic impact on the seismic wave propagation characteristics, the depth of paction several times with the RCC and incremental, 5m in the depths of the degree of paction of up 90%92%. Impact Roller is static shock, vibration and rub it smashes the prehensive role for large fill, Collapse dry sand and soil filling the paction. Asphalt paver Weiping equipment is operating principles of mechanical engineering innovation typical example. Fung plate diesel, liquefied petroleum gas or electric heating and 60 Hz frequency of vibration, and using infrared, ultrasonic or laser leveling, is a multidisciplinary hightech applications. This leveling the technology can be applied to the ground plane, as amlodipine or fine leveling the slope. Transfer frequency mechanical vibration is also monly used for drilling, stone crushing and sieving and Shen pulling piling works. The stone drying can use diesel, fuel oil and coal bustion of various fuels on the asphalt from the barrel, heating and asphalt mixture, stirring and insulation process is the full use of thermal theory of physics. Asphalt emulsion and some are modified chemical reaction physical specific application. drive innovation : universal hydraulic and electric drive 邵陽學院畢業(yè)設計（論文） 4 Hydraulic drive in the 20th century, the 1960s applied to the roller, only 10 years on the time has been spread and popularize. Now roller travel, vibration, steering and braking systems has achieved the full hydraulic drive. Hydraulic drive greatly simplified the roller drive and control system design, hydraulic drive a smooth, convenient manipulation effort, easy to achie
