从金刚石砂轮在磨削过程中,磨损颗粒脱落时结合剂桥破坏面的强度极限与磨削力的关系出发,推导了金刚石砂轮磨损颗粒脱落的自砺条件公式,并分析研究了金刚石砂轮磨损颗粒脱落的自砺条件因素。根据磨削不同的工件材料及所要求的磨削用量,自砺条件公式为生产具备良好自砺性能的金刚石砂轮提供理论依据。 相似文献

A neuron proportion integration (PI) control strategy for semi-active suspension system of tracked vehicle was proposed based
on its unique structure and the multiple and complex environment of the driving traffic. An adaptive genetic algorithm is
used to optimize the parameters of the neuron PI controller. The simulation result of the neuron PI control for semi-active
suspension system of tracked vehicle indicates that the vertical amplitude, pitch angle and vertical acceleration of the vehicle
are well controlled. The root mean square (RMS) of the vertical amplitude decreases by 37.2%, and 45.2% for the pitch angle,
38.6% for the vertical acceleration. The research of neuron PI control experiment for the semi-active suspension system of
the tracked vehicle model mining in benthal indicates that the RMS of the weight acceleration vibrating along the vertical
direction decreases by 29.5%, the power spectral density resonance peak of the acceleration of the car body decreases by 23.8%. 相似文献
