“…In fact, those existing methods to measure the contact force, such as displacement approach, acceleration approach and so on can not be used to obtain reliable results. During the last two decades, Laser Doppler Anemometry (LDA) technique, which is used in measuring fluid field in fluid mechanics, has been successfully developed to the velocity measurement of solid bodies [7][8][9][10]. Wu and his cooperators [11] successfully expanded LDA technique to monitor the velocity variation for a projectile impacting on a clamped beam or a clamped circular plate, thus the impact force history can be recorded much more precisely than before, and this method has been called as velocity approach.…”

A new elastic-plastic impact-contact model is proposed in this paper. By adopting the principle of minimum acceleration for elastic-plastic continue at finite deformation, and with the aid of finite difference method, the proposed model is applied in the problem of dynamic response of a clamped thin circular plate subjected to a projectile impact centrally. The impact force history and response characteristics of the target plate is studied in detail. The theoretical predictions of the impact force and plate deflection are in good agreements with those of LDA experimental data. Linear expressions of the maximum impact force/transverse deflection versus impact velocity are given on the basis of the theoretical results.

“…Previous studies [10][11][12][13] showed the effect of cage slip on the defect frequency response, bearing stiffness, and bearing damage. Markho et al 14 and Chen et al 15 observed a constant cage slip but a substantial, skewsymmetric variation in roller slip for different angular positions of rollers. In experimental investigations of the cage slip, how to measure the cage slip is a significant problem.…”

Although the cage slip of cylindrical roller bearings has been measured and studied experimentally, it is difficult to use current experimental measurement to detect the cage slip of the bearing in actual service or engineering environment. The problem is attributed to the limit on the space for current test instruments that can be installed arbitrarily in laboratory, but not in actual environment. A novel measurement based on strain detection is presented. This measurement can be used to obtain the cage slip of the bearing in service or large bench test. The technique is demonstrated and validated in principle by an experimental system. The system is developed to obtain the strain signal of the outer ring in loaded zone as well as the speed signal of the cage and the inner ring at the same time. Under given test load–speed conditions, the cage slip based on strain detection was compared with the cage slip based on speed detection. Experimental results showed that cage slip ratio curves based on strain responses agreed very well with those based on speed signals. In this way, it is revealed that frequency characteristics of strain signals can be used to obtain internal cage slip of cylindrical roller bearings.

“…Laser-Doppler Anemometry (LDA) technique has been successfully developed to the velocity measurement of solid bodies [8][9][10][11], especially as a non-contact measurement of the velocity history during the penetration process. Since a transient recorder was used to measure the instant velocity change of the striker during impact, merely a single differentiation was needed to obtain the acceleration history, for which errors incurred in the process are much reduced.…”

A Laser-Doppler Anemometry (LDA) was adopted to measure the velocity history of a projectile striking on an elastic-plastic clamped beam of rectangular crosssection. The acceleration history was obtained by differentiating the polynomial with respect to time and therefore the contact force history was obtained by multiplying the acceleration and the projectile mass [1]. In order to estimate the impact-contact process, a theoretical model is proposed, in which the indentation process, recovery process and separation process during the elastic-plastic contact history between the beam and the projectile are carefully considered. The experimental results are then compared with the estimates from the theoretical model. It is demonstrated that the theoretical model is capable of providing a good estimate to the contact force history for a beam subjected to a projectile impact. IntroductionIn study of impact on elastic-plastic structures, the impact force history is one of the most important objectives for researchers to achieve, because the force history is usually vital in evaluating the dynamic response and failure behavior of those structures such as pipes in nuclear power plant, helicopters and vehicles etc. However, unlike the displacement measurement, the impact-contact force history is difficult to be measured since the acceleration of the projectile is the double differentiation of the displacement with respect to time. Even a very small error in the displacement measurement may result in a significant difference of the Engineering Plasticity and Impact Dynamics Downloaded from www.worldscientific.com by MONASH UNIVERSITY on 04/23/17.
