Introduction Lower extremity injuries, in particular the foot/ankle are one of the most common in automotive crashes.[1] Although not life threatening, they can lead to long term medical complications or permanent disability[2]. In most cases foot and/or ankle fractures are caused during frontal automotive crashes, while the driver attempts an emergency brake and the foot is subject to crash lo...

The aim of this study is to examine the effects wearing high-heeled shoes (HHS) by comparing flat on first metatarsal bone using finite element method. modeled from computerized tomography (CT) image as 3D and imported ANSYS Workbench Software. Body weight (BW) muscle forces were applied bone. was fixed at proximal region for boundary conditions. Three evaluation criteria examined results stres...

In this paper, a greenhouse tomato picking robot chassis that meets the path cruising and setpoint positioning requirements of robots engaged in operations China is designed. Based on trellis-cultivation growing environment tomatoes, basic parameters operating space are analyzed to determine during operations. According these requirements, kinematic model with front-wheel steering rear-wheel dr...

While the basic principles of thermodynamics have remained same, necessity for heat exchangers to good effectiveness in a small volume is constantly growing. Heat type Matrix Exchanger (MHE), which can meet these requirements, does not an optimal design variant its use. These been approached 60 years, by many researchers, currently offering only overview process. The mechanism transfer matrix e...

High voltage (HV) cables are widely used in the transmission and distribution of electrical energy. The design manufacture these with great precision importance for power systems. Mistakes made during manufacturing phase defects that may occur structure cable material can cause premature aging continuous malfunctions cables. Factors such as air gaps, foreign substances, moisture insulating punc...

The development of jet nebulizers for medical purposes is an important challenge of aerosol therapy. The performance of a nebulizer is characterized by its output rate of droplets with a diameter under 5 µm. However the optimization of this parameter through experiments has reached a plateau. The purpose of this study is to design a numerical model simulating the nebulization process and to com...

The rocket motor test stand is the equipment used to motor's performance under controlled conditions. This measure thrust of Dextrose and ability components such as tube, fuel, nozzle cap itself. Before flight carried out, it must go through this test. In study, variations in are 2000, 2250, 2500, 2750, 3000 N. stands Aluminum 6063-T6 which has light density medium strength. Numerical simulatio...

ABSTRACT Pelton turbines are hydraulic turbines which are widely used for large scale power generation. A micro hydelpelton turbine is miniature model of actual pelton turbine which can be used for small scale power generation. This type of turbines converts potential energy of water at height into kinetic energy by allowing the water to fall freely on the pelton runner. This water impact provi...

Composite materials are manufactured by the combination of two or more distinct materials. The different form characteristics composites. Solid and stiff reinforcement is often inserted into a ductile matrix in aluminium-reinforced composites, which aim to increase mechanical properties, particularly strength, strength-to-weight ratio, etc. This study was focused on preparation data tensile pro...

The reaction forces at the tungsten support probes of a platinum microwire are determined by numerical analysis for different push-pull sliding velocities and contact pressures. Finite Element Analysis (FEA) tool ANSYS Workbench is used to evaluate stresses, deformations microwire. nonlinear formulations implemented ensure that maintained with during motion, transfer frictional between surfaces...
