Modern construction machinery industry of technical progress
章子怡 英语>jlc
Large-size mechanical mining excavator is ud widely in international and domestic engineering construction and mining performance, and its property defines the efficiency becau the international market is opened step step, how to promote the quality of excavator is the key that a factory reinforces its competing 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 lf-design is not enough and the basic work has not done perfectly especially the excavator kinetics .
The construct of excavator is very complex 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 computing ,but also do necessary work about the kinetics of mechanism to qualify the dynamic reliability in the period of designing .Trough the kinetic 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. Chine and foreign engineering machinery technology products come from a maturity period of modernization along with a new technological revolution, Mechanical engineering products integrated technology to a new level. Electronic technology, micro-computer, nsors, electro-hydraulic rvo control system integration and transformation of the traditional mechanical engineering products, Computer-aided design and computer-aided manufacturing and computer-aided management of construction machinery and equipment manufacturing, IT network technology equipment, construction machinery sale
s and information transfer systems, thus enabling people to e 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. 申请美国大学
1、allege operating principles of Innovation : groundbreaking new law with the high-frequency vibration
With scientific and technological rearch 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 compaction, etc.. The operations Jimmy initially bionics and Newtonian mechanics-bad, Modern science and the development of engineering machinery operating principle of laying the foundation for innovation. For example, mechanical vibration and pul jet, the photoelectric effect and thermal physics, the application of mechanical engineering to save resources and improve the quality of c

powersupplyonstruction improve production efficiency, reliability and driving comfort and a degree of automation to create conditions.
Excavators, bulldozers, loaders, and other earthmoving machinery cutting groundbreaking project, we had no struggle milling, high-frequency vibration, Liquid gas jet method and porous ground breaking law. Groundbreaking u of the new operating principle of transformation to a bucket, can loon the soil excavation for the high-intensity rock, Under normal circumstances can reduce the unit cost of earthwork and improve production efficiency, and the soil near the building when substitute bored-blasting method.
Vibratory Roller is a mechanical vibration and have reached a "sluggish vibration to" operational effectiveness of the most powerful note. High-frequency vibration compaction technology is the application of modern dynamics in the mechanical engineering important rearch results, In vibratory roller simultaneously with the application of vibration isolation theory. 90s of the 20th century, there have been a level of vibration (vib
celebratedbunchration) and vertical vibration directional vibration compaction method, and an AM-vibration and different from the harmonic vibration of chaotic vibration vibratory compaction operating principle, and the formation of the corresponding ries of vibratory roller. Impact Roller broke the existing traditional cylindrical roller structure, U 3-5 edge with the pressure roller polygon dragged by a tractor, 2-3 times per cond in order to impact on the ground. This has dramatic impact on the ismic wave propagation characteristics, the depth of compaction veral times with the RCC and incremental, 5m in the depths of the degree of compaction of up 90%-92%. Impact Roller is static shock, vibration and rub it smashes the comprehensive role for large fill, Collap dry sand and soil filling the compaction.
Asphalt paver Weiping equipment is operating principles of mechanical engineering innovation typical example. Fung plate diel, liquefied petroleum gas or electric heating and 60 Hz frequency of vibration, and using infrared, ultrasonic or lar leveling, is a multidisciplinary high-tech 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 commonly ud for drilling, stone crushing and sieving and Shen pulling piling works. The stone drying can u diel, fuel oil and coal combustion of various fuels on the asphalt from the barrel, heating and asphalt mixture, stirring and insulation process is the full u of thermal theory of physics. Asphalt emulsion and some are modified chemical reaction physical specific application. 韩文翻译器在线翻译
