Autodesk Moldflow is a simulation package for plastic injection molding. As part of the solutions for Digital prototyping, it helps CAE analysts and manufacturers optimize the design of plastic parts and injection molds. In general, models of the plastic parts are created at the first stage of product optimization and the major concern is the manufactured quality of the parts. Once the product ...

Hybrid control system composed of a base isolation system and a magneto-rheological damper so-called smart base isolation is one of effective semi-active control system in controlling the seismic response of structures. In this paper, a design method is proposed for designing the smart base isolation system in order to achieve an effective performance under multiple earthquakes. The base mass, ...

A new robustness evaluation method based on the specified story ductility ratio is proposed for a building model with uncertain oil dampers. Since influence of input motion uncertainty response variation can be simply taken into account, critical double impulse used instead ground motions. In method, function derived as velocity amplitude ratio. This procedure suitable performance-based design....

An integrated approach for all necessary variations within direct analysis, variational design sensitivity analysis and shakedown analysis based on Melan’s static shakedown theorem for linear unlimited kinematic hardening material behavior is formulated. Remarks on the computer implementation and numerical examples show the efficiency of the proposed formulation. Important effects of shakedown ...

This paper describes design and analysis of Spur gear. In the present work, it is proposed to substitute the metallic gear of sugarcane juice machine with plastic gears to reduce the weight and noise. For the purpose of two different types of plastic materials were considered namely Nylon and Polycarbonate and their viability are checked with their counterpart metallic gear (Cast iron). Based o...
