【摘要】：挖掘装载机是一种既能完成挖掘作业又能完成装载作业的工程机械。它能实现一机多用，应用前景比较广泛，随着发达国家对工程机械安全性能要求的不断提高，进入欧美市场的工程机械必须配备翻车保护装置。这就要求生产厂家设计的驾驶室必须带有翻车保护结构，并且通过试验获取CE认证证书，，为挖掘装载机出口欧美铺平道路。在此要求下本文针对公司的挖掘装载机ROPS进行了设计、计算机仿真和试验，主要内容如下：（1）.依据挖掘装载机敞篷驾驶室ROPS设计原则，结合之前设计驾驶室ROPS的成功经验，设计了一款挖掘装载机四立柱敞篷驾驶室的翻车保护装置（ROPS）。（2）.应用HYPERMESH软件对此结构进行网格划分，用ANSYS有限元分析软件对挖掘装载机敞篷驾驶室ROPS的侧向、垂直和纵向承载能力以及最小能量吸收能力进行了有限元分析。（3）.按国际标准要求，对本公司生产的A系列挖掘装载机敞篷驾驶室的ROPS进行了试验且一次性顺利通过，对其产品的合格性作出了科学的认证，并获得证实，为公司产品顺利出口欧美等需满足CE要求的地区提供了有力的保障。并将试验结果与仿真分析结果进行比较，比较结果表明ROPS仿真分析方法具有一定的实际应用价值，为今后合理的设计驾驶室提供了理论基础。
[Abstract]:Excavating loader is a kind of construction machinery which can finish both excavating and loading.It can realize a multi-purpose and has a wide application prospect. With the increasing requirements of the developed countries for the safety performance of construction machinery, the construction machinery entering the European and American markets must be equipped with a turning over protection device.This requires that the driver's cab designed by the manufacturer must have a capsize protection structure, and obtain CE certification through tests, paving the way for excavating loaders to export to Europe and the United States.Under this request, this paper has carried on the design, the computer simulation and the experiment to the excavating loader ROPS of the company, the main content is as follows:There is no such thing as a bird.According to the principle of ROPS design for the cab of excavating loader, combining with the successful experience of designing cab ROPS before, this paper designs an overturning protection device for the cab of excavating loader with four columns.There are two pieces of water.The HYPERMESH software is used to mesh the structure, and the ANSYS finite element analysis software is used to analyze the lateral, vertical and longitudinal load-carrying capacity and the minimum energy absorption capacity of the excavated loader cab ROPS.3.According to the requirements of international standards, the ROPS of the A series excavating loader cabs produced by our company has been tested and passed successfully at one time, and the conformity of its products has been scientifically certified and verified.For the company to export products to Europe and the United States to meet the CE requirements of the region to provide a strong guarantee.The comparison between the test results and the simulation results shows that the ROPS simulation analysis method has some practical application value and provides a theoretical basis for the reasonable design of cab in the future.
