为了使挖掘机发挥最大能力,满足铲斗机构设计要求的基础上,以总传动比为优化目标,建立了一系列的约束条件,并运用ADAMS技术对其参数进行优化设计。通过对比设计原始值和优化值,结果表明优化后的铲斗机构能发挥更大的挖掘力,对挖掘机后续结构设计有一定的参考价值。 In order to maximize the excavator capacity and meet the design requirements of the bucket mechanism, a series of constraints were established with the total transmission ratio as the optimization objective. The parameters of the excavator were optimized by ADAMS technology. By comparing the original design value and the optimized value, the result shows that the optimized bucket mechanism can exert more digging force and has certain reference value to the subsequent structural design of the excavator.
