چکیده
Dynamic characteristics of a prototype AEM, designed based on a hydraulic engine mount, has been investigated and an adaptive controller for the AEM has been designed. An equivalent mass-spring-damper AEM model is proposed, and the transfer function that describes dynamic characteristics of the AEM is deduced from mathematical analysis on the model. The damping coefficient of the model is derived by considering nonlinear flow effect in the inertia track. Experiments confirmed that the model precisely describes dynamic characteristics of the AEM. An adaptive controller using the filtered-X LMS algorithm is designed to cancel the force transmitted through the AEM. The stability of the LMS algorithm is guaranteed by using the secondary path transfer function derived based on the dynamic model of the AEM. The performance test in the laboratory shows that the AEM system is capable of significantly reducing the force transmitted through the AEM.

The invisible hands of peer reviewers play a determining role in the eventual fate of submissions to international English-medium journals. This study builds on the assumption that non-native researchers and prospective academic authors may find the whole strive for publication, and more specifically, the tough review process, less threatening if they are aware of journal reviewers’ expectation...
متن کاملFinite Element Analysis of Different Hip Implant Designs along with Femur under Static Loading Conditions
Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...
متن کاملIdentifying and classifying the factors affecting risk in automobile hull insurance in Iran using fuzzy Delphi method and factor analysis
Automobile hull insurance has attracted much attention due to the high rate of vehicle applications in daily lives. Since purchasing these policies is optional in Iran and their premium rates are set competitively, a competition is formed among the insurance companies for attracting low risk drivers. However, most of the insurers still use comparative rates and pay no or less attention to the f...
متن کاملAssessing Prevalence of Musculoskeletal Disorders in Women Workers in an Automobile Manufacturing Assembly Line
Background: Work-related musculoskeletal disorders (WMSDs) may involve all parts of the body, and have been a worldwide problem. Employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more WMSDs because of high rate of repetitive motions. Methods: The aim of this study to determine the prevalence of WMSDs in women workers of an automobi...
