磨损过程 meaning in English
wear process
Examples
- On the one hand , there is grea t influence of temperature field factor and reliability theory on the wear process of parts , which cannot be ignored ; on the other hand , because of the uncertainties of outer circumstances were longevity should adopt the expression form of probability longevity
一方面,温度和应力一样对零件的磨损过程影响很大,都应纳入磨损的计算过程中;另一方面,外界环境的不确定因素很多,磨损寿命应该采用概率寿命的表述形式。 - In this study , based on bispectrum and bicoherence extraction of vibration acceleration signals at spindle end of a vertical machining center while milling operation , change rules of bispectrum and bicoherence of the signals were analyzed for the progressive wearing process of the flank wear land of the milling cutters
通过提取铣削加工过程中机床主轴端振动加速度信号的双谱及其双相干系数,分析了铣刀后刀面渐进磨损过程双谱及其双相干系数的变化规律。 - On the basis of the theory of fractal geometry , the fractal dimension characters of ae signal at different tool wear states were analyzed , an algorithm was provided to decide the scale range which is necessary to calculate the dimension of non - fully - fractal form . the experiments showed that the fractal dimension of ae signal is slightly effected by the changes of cutting parameters ; the variance of the fractal dimensions , which reflects the geometric characters of ae signals , has the same tendency as that of the flank wear , the monitoring system , which takes the fractal dimension of the ae signal as the feature , can identify the different tool wear states more correctly under different cutting conditions
以分形几何理论为基础,对刀具不同磨损阶段声发射信号的分形特征进行分析.提出了计算非完全分形体信号波形的关联维数时尺度范围的确定方法,分析了声发射信号在刀具磨损过程中分形维数的变化特性.刀具磨损切削实验数据表明,声发射信号的分形维数受切削参数变化影响较小;分形维数反映了声发射信号的几何特征,其大小能较好地反映刀具的不同磨损状态.实验结果表明,该方法能正确地实时在线监测刀具的不同磨损状态 - A series of tests were performed on the self - made fretting wear test rig to examine the fretting wear of steels , by taking the wear depth of steel wires as a characterization parameter describing the fretting wear in relation to contact load and fretting time . the results demonstrates that the fretting wear depth increases with the increasing of the contact load and fretting time
结果表明,钢丝试样的微动磨损深度随着接触载荷和微动时间的增加而呈增长趋势,但由于接触面积和接触应力在微动磨损过程中随着接触载荷和微动时间的变化而变化,使磨损深度在不同磨损工况下增长趋势不同。 - The results show that : the whole bit wear process can be divided into three phases ; the regularity of the machining time per hole with the number of holes machined is close to a periodic variation ; higher machining efficiency or working life can be obtained when the drilling pressure and the wall thickness of the bit are advisable
发现钻头的整个磨损过程可分为3个阶段;孔加工时间随孔数近似呈周期性变化;钻压和钻头壁厚适当时,可获得更高的加工效率或者工具寿命。
