【正文】 1 中英文翻譯 英文原文： Modern construction machinery industry of technical progress Largesize mechanical mining excavator is used widely in international and domestic engineering construction and mining performance, and its property defines the efficiency because the international market is opened step step, how to promote the quality of excavator is the key that a factory reinforces its peting force. In our country， the designing elevation and production quality on excavator can not keep up with international advanced technology applying on the advanced technology has already applied advanced designing method on excavator designing， such as electronic simulating theory， dynamic design， reliability design and so in our country ,the most excavator design has still applied the traditional design method ,the modern design method has not began to be actually applied .The prime display is that the capability of selfdesign is not enough and the basic work has not done perfectly especially the excavator kiics . The construct of excavator is very plex and the multiple movers often work the same time its working environment is very bad and the eternal load varies a result ,when designing the new product of excavator ,in order to ensure the performance safety， the designer not only has the basic theory analysis on static load puting ,but also do necessary work about the kiics of mechanism to qualify the dynamic reliability in the period of designing .Trough the kiic analysis ,the load property of all the elements in excavator can be decided so as to design reliable product . From the 1980s of the 20th century to the beginning of this century. Chinese and foreign engineering machinery technology products e from a maturity period of modernization along with a new technological revolution, Mechanical engineering products integrated technology to a new level. 2 Electronic technology, microputer, sensors, electrohydraulic 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 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 c
