查询词典 string block

Analysis is made on block effect to cutters of PDC bit with 3 factors: different top shape,cutter-distributing and wearing degree.By the interaction(radial range and altitude difference of each cutter) of three adjacent cutters,the cutter block is further analyzed with these factors,but wearing degree is simplified to be considered as the cutters vertical to the assembling plane.

中文摘要：对PDC钻头冠部形状及不同的布齿密度和切削齿在不同的磨损状态下对PDC钻头切削齿受力的影响进行了分析；用相邻的3个切削齿之间的关系（不同的切削齿与切削齿之间的径向距离和切削齿之间的高度差）来分析PDC钻头冠部形状和切削齿布齿密度对切削齿受力的影响，以及将切削齿的磨损状态简化成与切削齿在钻头上装配方向垂直的平面来分析切削齿磨损状态对切削齿受力的影响。
