【正文】 s a thinking mind (microputer) sensorium (sensors), neural work (electronic transmission). Derrnatopathy (power and transmission), and hand, foot bones (work with devices running) for telemunications systems integration. Machine is not electromechanical integration of telemunications and information technology with a simple, it poses the system must have five functions : ① detection and identification with the objects of their work and working conditions of the function。s stability。s major panies have attached great importance to the products of industrial design, and a specialized research and design. A world leader left the pactor manufacturers BMW, his third of the mechanical paction machine modeling experts from the industrial design design, have a good overall result. The series dismounting replacement filter, transmission pieces, hoses and routine maintenance is very convenient. Adopt modern arcshaped dip in the cab and the engine hood broadminded, fluent lines, with the flavor of the times. Driving the steering wheel height and angle adjustable, choose a fortable high back seats adjustable damping. Drivers prepare for a good operating environment. Instrumentation site design, easier to observe and control, tilt hood of the driver to provide a good perspective. Hydraulic steering gear shifted to the cab, driving to reduce indoor heat and noise. Arcshaped windscreen of the cab and four SUPPORT able to isolate noise and vibration. indoor noise below 70dB (A). Many other engineering machinery are also different degrees of emphasis on industrial design, layout ponents such as depression, to reduce the center of gravity of the aircraft。 with the acoustic interference, This antinoise and the engine exhaust noise offset, which over the purpose of the muffler. Such a muffler can be used to eliminate the basic engine noise and the noise indoor driving. Muffler and isolation through the engineering machinery driving indoor noise can be reduced to 70dB (A) below. In addition, by concentrating on lubrication, automatic lubrication and fault alarm, greatly reducing the engineering and mechanical maintenance workload. Dreiser panies axis articulated loader lubrication cycle extended to 2020h. oil and filter replacement cycle extended to 250h。s operational procedures and to the machine39。s largest engineering machinery manufacturing pany has invested considerable human and financial resources for modern design methodology of the research and used. Ergonomics is a peopleoriented design, with emphasis on the machines mutual coordination and crew safety, driving fort, convenience in the driver39。邵陽學院畢業(yè)設計（論文） 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. 邵陽學院畢業(yè)設計（論文） 2 Electronic technology, microputer, sensors, electrohy
