滑移现象 meaning in Chinese
slip phenomenon
Examples
- At last , in according to the experiment results , the interpretation of the mechanism of the slip phenomenon of prepressing - contact spring - damping system was given in this dissertation . further more , the relationship among the limit frequency , the value of prepressing , excitation frequency , the amplitude of excitation and the materiel parameter was analyzed . base on the theory analysis the limit frequency formula was given , and the contact - slip condition for engineering application was concluded
最后根据理论研究与试验分析的结果，分析预紧接触式弹簧阻尼系统产生滑移现象的机理以及共振峰值漂移现象的理论解释，并通过定性分析接触分离时的频率与预紧量、激励频率、激励力幅值以及垫层的材料参数之间的关系，提出能定量描述系统出现滑移现象的极限频率公式，总结了预紧接触式结构始终保持接触的条件。 - Because of the former anchorage systems designed according to matching 1860mpa strength strands in the beginning of 90 " , they can not be suitable any more for the super strength strands with 2000mpa . therefore , some accidents occurred such as strands sliding and broken when tensioning . in addition , the advantages of the new materials as their high mechanics performance are not be used completely as the prestressing structures was designed as per the 1860mpa strands , which will result in the waste of materials , in view of the above - mentioned facts , by means of analyzing the development of anchorage systems home and abroad , in connection with the characteristics of the super strength strands ( 2000mpa ) , this topic made a research on hvm15 anchorages by theoretical calculation and finite element analysis , and also on the manufacturing process and test
随着预应力技术的发展和冶金工业冶炼技术的不断进步，预应力钢绞线的强度不断提高，由原来1470mpa提高到1860mpa ， 90年代末期已出现了2000mpa超高强钢绞线，而原来的是在90年代初期按抗拉强度为1860mpa的钢绞线标准设计的，因此，原有的锚具已不能适应现有超高强度2000mpa的钢绞线强度要求，在工程中出现了断丝滑移现象，同时，在使用和设计时仍按1860mpa钢绞线的指标进行设计应用，没能充分发挥材料的力学性能，造成材料浪费。
