摘要
The influence of taper contamination on the static and dynamic characteristics of a slider is studiedin detail. Two models of taper contamination, including the effect of skew angle and the number of the railwith taper contamination as well as the amount of contaminator on the taper,are investigated respectively. Anequivalent scheme is applied to evaluate the frequency responses with different flying attitudes in three de-grees of freedom. Ca1culations show that whether model is considered and how many tapers are contaminated,the static and dynamic characteristics of the slider change little in a very large contamination scale,but oncethe amount of contaminator exceeds some limit,the flying attitude of the slider is degraded catastrophically,which is easy to cause the slider crash. The skew angle,when it is large enough,may ameliorate or deterioratethe flying characteristics of the slider depending on the slider attitude when the transverse air flow passesthrough it.
