Abstract Scheme design is an important creative stage of product design. How to analyze, compare and evaluate different design schemes qualitatively and quantitatively is an open problem to be solved in the field of design. This paper presents a quantitative analysis and calculation method for analyzing, comparing and evaluating the different design schemes of backhoe devices. The method consists of defining three kinds of different spaces for the description of backhoe devices' workspace, establishing the kinematics model of backhoe devices in joint space and solving the kinematics model to obtain the workspace by using the Monte Carlo method, and it can select the optimal design scheme from various scheme designs of backhoe devices. Then taking a backhoe device for the XG809F excavator as a case study, the design scheme selected by our method is the optimal scheme. It is verified by simulation methods and experiments, which demonstrates that the proposed method is an effective and practical quantitative analysis method for analyzing, comparing and evaluating the different design schemes of backhoe devices. Finally, it is pointed out that the distribution of excavation force of backhoe devices in their workspace is the direction for follow-up research at the end of the paper.

液压挖掘机反铲装置的工作空间描述与仿真

摘要 方案设计是产品设计的一个重要创意阶段。如何定性和定量地分析、比较和评价不同的设计方案,是设计领域亟待解决的一个开放性问题。本文提出了一种定量分析计算方法,用于分析、比较和评价不同的反铲装置设计方案。该方法包括定义三种不同的空间来描述挖掘装置的工作空间,在关节空间建立挖掘装置的运动学模型,并利用蒙特卡罗方法求解运动学模型获得工作空间,并且可以选择从反铲装置的各种方案设计中优化设计方案。然后以XG809F挖掘机的反铲装置为例,我们的方法选择的设计方案是最优方案。通过仿真方法和实验验证,表明该方法是一种有效且实用的定量分析方法,可用于分析、比较和评价不同的反铲装置设计方案。最后指出反铲装置在其工作空间内的挖掘力分布是论文最后的后续研究方向。
