This study proposes a new correlation improvement technique for the optimum node removal location to get improved modal assurance criterion (MAC) matrix. The technique is applied to updating of the finite element model (FEM) of a structure. The developed routine is tried on a utility helicopter. It is proven that it is capable of showing better performance than the coordinate MAC (coMAC), commonly used in such analyses. Commercial software is utilized for the finite element analysis of the helicopter fuselage and tail. Experimental modal analyses are also performed for updating the model for t ...Daha fazlası
This material is designed to complement the course Reading and Writing at B1 and B2 levels. It not only provides numerous activities from simple to complex but also raises awareness for the morphological and syntactic aspects of English grammar. Therefore, the book may easily be regarded as a stand-alone source for those who begin to develop their writing abilities in English as a foreign language. However, it still assumes some background as almost all students who are enrolled at the Preparatory School are fresh graduates form high schools around the country. Finally, given the experience an ...Daha fazlası
This book is the first of four-series general English course designed for adult and young adult learners. Its syllabus is balanced in speaking, reading, writing and listening skills, providing ample means to learn vocabulary and grammar for the CEFR A1 level. It is built upon real-life needs keeping in mind pre-academic objectives for communication. To enhance communicative language education, pair work and group work activities are emphasized. The book also provides additional materials for self-study and practice. Progress English is based on: Integrated skills A balanced syllabus Extra reso ...Daha fazlası
In this study, modeling of a helicopter fuselage panel with active vibration control is carried out. In order to represent the helicopter body shell, a cabin panel clamped from four edges is designed. Piezoelectric patches are attached on the body according to the literature. The dynamic characteristics of the structure are obtained by finite element based modal analysis and exporting of state space matrices. The numerical model of the cabin panel is characterized with regard to active vibration control loop. Vibration data obtained from the helicopter operational tests is applied as a distort ...Daha fazlası
Failure of metallic structures operating under shock loading is a common occurrence in engineering applications. It is difficult to estimate the response of complicated systems analytically, due to structure's dynamic characteristics and varying loadings. Therefore, experimental, numerical, or a combination of both methods is used for evaluations. In this study, test pieces made of two different materials are subjected to shock loads stemming from firing of a Gatling gun. Strain measurements are made, and finite element analysis of the test piece is performed. As a result of this study, strain ...Daha fazlası
