  伸缩臂挖掘机是工程呆板中从事土方工程施工的紧张呆板装备之一,普及运用于筑路工程、房屋配置、水利配置等范围。今天南方双彩网就来为大家讲授伸缩臂挖掘机载荷谱实行实际意义以供大家参考。
  Telescopic arm excavator is one of the main mechanical equipment in construction machinery, which is widely used in road construction, housing construction, water conservancy construction and other fields. Today we will explain the practical significance of load spectrum test of telescopic excavator for your reference.
  伸缩臂挖掘机的变乱载荷庞大多变,在交变载荷的作用下,各关键构件容易孕育发生委顿失效。实际工程中,委顿粉碎的发生占全部力学粉碎环境的50~90,是呆板、布局失效有数的情势之一
  The working load of telescopic boom excavator is complex and changeable. Under the action of alternating load, fatigue failure of key components is easy to occur. In practical engineering, the occurrence of fatigue failure accounts for 50-90% of all mechanical failure, which is one of the common forms of mechanical and structural failure.
  日本对中型液压伸缩臂挖掘机拦阻环境观察统计的结果是,金属质料拦阻占总拦阻的35%,而变乱装置拦阻约占金属质料拦阻的60(包括委顿、脆性、磨损及变形)。由此可见,布局件的委顿是影响南方双彩网产品运用结实性的关键标题之一。为了深化相识委顿失效并研讨技巧的临时性与结实性,需要为呆板关键零部件变乱装置载荷谱的征求和室内委顿结实性实行提供典范工况,即在实行进程中模拟并再志向际工况下的载荷,并在该工况下测定载荷数据信息,工况包括作业模范、作业介质等。因此,展开伸缩臂挖掘机紧张作业介质及所占比例和紧张作业模范及所占比例的观察研讨变乱,对载荷谱实行及载荷谱整理至关告急。

  According to the investigation and statistics of the faults of medium-sized hydraulic telescopic boom excavators in Japan, the metal material faults account for 35% of the total faults, while the working device faults account for about 60% of the metal material faults (including fatigue, brittleness, wear and deformation). Thus, the fatigue of structural parts is one of the key issues affecting the reliability of products. In order to deeply understand fatigue failure and study the durability and reliability of techniques, it is necessary to provide typical working conditions for the collection of load spectra of key parts of machines and the indoor fatigue reliability test, that is, to simulate and reproduce the loads under actual working conditions during the test process, and to measure the load data information under such conditions, including the type of operation, working medium, etc. Therefore, it is very important for load spectrum test and load spectrum arrangement to carry out investigation and Research on the main working medium and proportion, main working types and proportion of telescopic boom excavator.
  依据载荷谱实行的实际需求颠末对伸缩臂挖掘机紧张作业介质及所占比例、紧张作业模范及所占比例等关键标题举行了观察统计和阐发,区分失失大型和中型伸缩臂挖掘机的紧张作业介质和每种介质所占比例;同时失失伸缩臂挖掘机紧张作业模范及所占比例,为载荷谱实行的展开和数据整理提供了依据,具有告急实践意义。
  According to the actual demand of load spectrum test, the main working medium and its proportion, main working type and proportion of telescopic boom excavator are investigated and analyzed, and the main working medium and the proportion of each medium of large and medium telescopic boom excavator are obtained respectively. At the same time, the main working type and proportion of telescopic boom excavator are obtained as load. The development of charge spectrum test and data collation provide a basis and have important practical significance.
