Aircraft’s constant operation in tough conditions necessitates the need for structural components of high strength yet low weight. Composite materials are being used as an alternative to conventional aluminum alloys because their competitive strength-to-weight and stiffness-to-weight ratios. In this paper, detailed design procedure a light-aircraft composite material fuselage tooling three dime...
Design and analysis of propellant grain configurations for determination of the grain geometry which is an important and critical step in the design of solid propellant rocket motors, because accurate calculation of grain geometrical properties plays a vital role in performance prediction. The performance prediction of the solid rocket motor can be achieved easily if the burn back steps of the ...
Purpose – The purpose of this paper is to propose two simple tools for the kinematic characterization of hexapods. The paper also aims to share the experience of converting a popular commercial motion base (Stewart-Gough platform, hexapod) to an industrial robot for use in heavy duty aerospace manufacturing processes. Design/methodology/approach – The complete workspace of a hexapod is a six-di...
Within the computer aided design (CAD) teaching framework, new information and communication technologies (ICT’s) are being set through new tools and methodological changes: multimedia applications in different formats and mediums, specific software packages, virtual lecture rooms and campus, internet and its different resources, e-mail, etc. The aim of this article is to build a bridge between...
The present paper deals with design, construction and working of Accelerator and Brake operated by one pedal, which may be a technique for reducing road accidents. The main objective of this innovation is to eliminate the operator’s risk of pressing the wrong pedal at the time of emergency as well as reduction in the driver’s reaction time to switch from accelerator to brakes or vice versa. Thi...
In this paper we will present a mechanical study made on the design of thermal conductive plastic parts. Out our derived new rules that are useful for engineers have to create parts built from type materials. We used Catia V6 software modelling and ANSYS Moldflow simulate behaviour real components. The solutions resulted trials improving quality plastics. test simulation results lead us designi...
مقدمه: روش های متعددی برای ارزیابی ارگونومیکی عوامل خطرکمردرد در محیط کار وجود دارد که شامل روش های بیومکانیکی، فیزیولوژیکی و فیزیکی-روانی می باشند. مدل سازی دیجیتالی انسان(dhm) نیز ابزاری مبتنی بر کامپیوتر جهت ارزیابی ارگونومیکی بوده که دارای مزایایی هم چون صرفه جویی در وقت و زمان در ارزیابی ها و نیز ارزیابی فعالانه راهکارهای ارگونومی در محیط دیجیتالی می باشد. این مطالعه با هدف ارزیابی علل کمر...
