【摘要】 通过 WS-005挖掘机的试验及计算分析,提出了挖掘机在一次挖掘过程中斗齿尖的挖掘轨迹,可用对数螺旋线予以描述,确定了在该轨迹条件下,提升速度对推压速度的比值和斗齿切削角的变化规律,以及用等速比挖掘可实现对数螺旋线轨迹。更多还原

【Abstract】 By the experiments and analyses of model WS-005 excauator,the fact that the diggingtrack can be described as logarithm spiral curve is proved,the changes of the ratio of the hoist velocity to thecrowd velocity and the cutting angle are discussed,the logarithm sprial curve track can be realized while theexcavator digging with a constant velocity ratio.The digging irack is the basis of deteriming the excavator’s loads and some important parameters in thedigging process.更多还原
