【正文】 為電動機的能容量小，一臺電動機與同功率的液壓馬達(dá)相比，其重量和體積要大好多倍，這給機器的空間布置帶來了很大困難。 迪爾公司、卡特彼勒公司、德國利渤海爾公司及日本小松制作所都生產(chǎn)和銷售全液壓推寺機與裝載機。 調(diào)頻率機械振動還通常用于鑿巖、石料破碎與篩分及沉拔樁等工程施工。高頻振動壓實技術(shù)的應(yīng)用是近代動力學(xué)在工程機械上的重要科研成果，在振動壓路機上同時應(yīng)用了振動與隔振理論。新的工程機械產(chǎn)品在工作效率、作業(yè)質(zhì)量、環(huán)境保護、操作性能及自動化程度諸多方面都是以往所不可比擬的，并且在向著進(jìn)一步的智能化和機器人化方向邁進(jìn) 。 ⑤ z own selfprotection and security troubleshooting functions. This is the Intelligent Engineering Machinery some specific goals. In mechanical engineering intelligent process, from beginning to end, filled with selflearning technology and the use of adaptive technology. Now for the integration of telemunications technology for the engine and hydraulic system and electrical system of full control machines are being given various feelings and wisdom. In the process with the state of realtime 9 monitoring on the basis of mechanical engineering from the partial automation of the transition to full automation, and toward unmanned remote control and the trend of development. With the intervention of artificial intelligence, engineering machinery will accelerate its modern fast process, Gradual transition to a fully operational wisdom of the target robot. At that time, some new robotic operating procedures will e into being. 10 譯文： 現(xiàn)代工程機械行業(yè)的技術(shù)進(jìn)步 大型機械式挖掘機在目前國際國內(nèi)在礦山開采及工程施工中有著廣泛的應(yīng)用，其性能的優(yōu)劣對生產(chǎn)率有很大的影響 .在國際市場竟?fàn)幦遮吋ち业慕裉?，如何提高產(chǎn)品的質(zhì)量是提高其市場競爭力的關(guān)鍵。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。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
