[ 1 ] - Dynamic Stability Analysis of a Beam Excited by a Sequence of Moving Mass Particles
In this paper, the dynamic stability analysis of a simply supported beam carrying a sequence of moving masses is investigated. Many applications such as motion of vehicles or trains on bridges, cranes transporting loads along their span, fluid transfer pipe systems and the barrel of different weapons can be represented as a flexible beam carrying moving masses. The periodical traverse of masses...
[ 2 ] - تحلیل پایداری ارتعاشات عرضی ورق‌های مستطیلی شکل تحت عبور متناوب جرم‌های متحرک
در این پژوهش، پایداری ارتعاشات عرضی ورق مستطیلی شکل نازک با شرایط مرزی تکیه گاه های ساده که تحت عبور متناوب جرم های متحرک یکسان قرار دارد، با در نظر گرفتن تمامی ترم های اینرسی جرم های متحرک در تحلیل، مورد بررسی قرار گرفته است. در اثر عبور متناوب جرم ها از روی سطح ورق، یک مسأله ی پریودیک خطی حاصل می شود. از روش گالرکین، برای تبدیل معادله دیفرانسیل پاره ای ارتعاشات عرضی ورق به مجموعه ای از معادلا...
[ 3 ] - Optimizing the Torque of Knee Movements of a Rehabilitation Robot
The aim of this study is to employ the novel Adaptive Network-based Fuzzy Inference System to optimize the torque applied on the knee link of a rehabilitation robot. Given the special conditions of stroke or spinal cord injury patients, devices with minimum error are required for performing the rehabilitation exercises. After examining the anthropometric data tables of human body, parameters su...
[ 4 ] - Efficient Higher-Order Shear Deformation Theories for Instability Analysis of Plates Carrying a Mass Moving on an Elliptical Path
The dynamic performance of structures under traveling loads should be exactly analyzed to have a safe and reasonable structural design. Different higher-order shear deformation theories are proposed in this paper to analyze the dynamic stability of thick elastic plates carrying a moving mass. The displacement fields of different theories are chosen based upon variations along the thickness as c...
[ 5 ] - Designing and Creating a Virtual Reality Environment and a Wearable Glove with Control and Evaluation Capability to Rehabilitate Patients
Introduction: Using modern technologies like virtual reality in rehabilitation can promise a great movement in medical sciences as sometimes, these technologies shorten the path of reaching the goal. In the present study, a virtual reality environment with the ability of physical interaction was designed to test and measure the hand motion, and a sample of electronic equipment was presented alo...
