For the sake of realizing the structural lightweighting design on ball cage patterned constant speed universal joint , taking the maximum contact stress of ball cage patterned constant speed universal joint , overall contacting deformation and plastic deformation as foundations , a preliminary study was carried out respectively on two kinds of ball cage patterned constant speed universal joints with their number of balls as 6 and 8 摘要为了实现球笼式等速万向节的结构轻量化设计,以球笼式等速万向节最大接触应力、接触总变形和塑性变形为依据,分别对钢球数量为6和8的两种结构的球笼式等速万向节进行了初步研究。
Based on a large numbers of model / simulation test of the intermittent cracked rock - like samples , fatigue strength , fatigue deformation and crack appear in preexisting cracks tips , the growth of crack , the pattern of crack coalescence are studied / analysed systemically by means of cyclic load and static load , in the course of the model test , the difference between cyclic load and static load of crack appear in preexisting cracks tips , the growth of crack and the pattern of crack coalescence are observed and analysed 在试验过程中,观察并分析了循环加载方式下,预置裂隙端部裂纹萌生、扩展、岩桥贯通模式与静载方式下的差异;探讨了疲劳裂纹萌生、扩展的机理,分析了加载频率、荷载水平对裂隙试样疲劳强度、疲劳变形(总变形和不可逆变形)的影响规律。
