Isolation Performance

A linear dashpot is a common equipment used in shock and vibration isolation. It has been shown theoretically that the vibration isolation performance can be significantly improved by a damping profile that depends on the piston relative position. In this study, a position-dependent damping profile is realized by using electromagnetic principles. The idea is to have multiple coil windings on the outer cylinder and to use a magnet as a piston. The damping profile is tuned by changing the number of turns at each coil. As a result of the magnet-coil arrangement, the architecture also has the capability of being regenerative. A unique experimental setup is constructed that measures damping electrically in a multiple coil arrangement. Least-squares optimization method is used to tune the number of turns. It is shown that the coil turns can be successfully tailored to realize a desired damping profile. The position-dependent damping architecture has the potential to be used in future regenerative dampers.

In this paper, vibration characteristics of super-heavy vibrating shaker were simulated by using MATLAB based on the developed analytical models. The important stiffness test experiment of elastic component-shaker rubber spring in compression, shear stiffness and experimental verification of mechanical models were made. Results show that the test data was consistent with simulation data, which verified the correctness of design and analysis.

Modal Curvature

Sifat dinamik adalah fungsi bagi ciri-ciri fizikal. Sejak 20 tahun yang lalu, banyak usaha telah dibuat dalam menyiasat hubungan antara kerosakan struktur dan parameter modal. Banyak kaedah telah diperkenalkan dari kaedah langsung hingga penggunaan algoritma optimuman. Kebanyakan penulis membuat kesimpulan bahawa sifat-sifat dinamik boleh digunakan sebagai penunjuk kerosakan. Walau bagaimanapun, kebanyakan kerja tersebut telah disahkan melalui model simulasi dan bukannya pengesahan uji kaji. Oleh itu, kajian ini bertujuan untuk menyiasat kecekapan kelengkungan mod dan frekuensi tabii dalam pengesanan kerosakan melalui contoh uji kaji rasuk keluli keratan segi empat berongga. Tujuh senario kerosakan disimulasikan pada spesimen dengan menggunakan potongan giling bagi lokasi kerosakan dan keterukan yang berbeza. Kajian kepekaan kepada indeks kerosakan kelengkungan modal dilakukan dan isu-isu yang berkaitan dengan penggunaan data modal dibincangkan. Keputusan menunjukkan bahawa frekuensi tabii adalah penunjuk kewujudan kerosakan yang sensitif. Sementara, kebolehpercayaan kelengkungan modal pula adalah agak terhad dan amat bergantung kepada ketepatan pengukuran. Kata kunci: Pemantauan kesihatan struktur; ujian modal; data modal Dynamic properties are the functions of physical properties. Over the past 20 years, considerable efforts have been made in investigating the relationship between structural damage and modal parameters. Many methods have been introduced ranging from direct methods to application of optimization algorithms. Most of the authors concluded that the dynamic properties are feasible as damage indicators. However, most of the works are validated through analytical models instead of experimental verification. Thus, this study aims to investigate the efficiency of modal curvature and natural frequencies in damage detection through an experimental example of a rectangular hollow section steel beam. Seven damage scenarios are simulated on the specimen using grinder cuts for different damage location and severity. Sensitivity study on the damage index of modal curvature is performed and issues related to the application using modal data are discussed. The results show that natural frequency is a sensitive damage existence indicator. While, the reliability of modal curvature is quite limited and very much depending on the accuracy and precision of measurements. Key words: Structural health monitoring; modal testing; modal data
