MODELING, SIMULATION AND OPTIMIZATION ANALYSIS OF STEERING KNUCKLE COMPONENT FOR RACE CAR
Light weight and low fuel consumption are the two main demands for a vehicle, particularly for a race car. Steering knuckle, as one of the critical components of a race car, is the main subject in the present study. A light weight and optimized design of steering knuckle is proposed to be used for an EIMARace race car; a small high-performance formula-style car, with suitable material selection as well as valid finite element analysis and optimization studies. First part of this study involves modeling of steering knuckles and analysis of the stresses and displacement under actual load conditions. A CAD and FEA software; SolidWorks, is applied for modeling as well as for static analysis studies. Shape optimization is the second part of this study, utilizing solid Thinking software from Altair Engineering packages. The improved design obtained had achieved 45.8% reduction of mass while meeting the strength requirement.
Design, analysis and optimization of steering knuckle for all terrain vehicles
The vehicle consists of various physical components which support smooth operation and ensure the safety running during off road conditions. Steering knuckle is one such component with an unconventional shape and it not only act as the connecting entity between steering, brake and suspension system, but also links chassis and wheel hub. Even it is the high stress bearing and critical component of an All-Terrain Vehicle (ATV). The component of knuckle experiences greater magnitude of forces amidst the automotive suspension elements such as shock absorber. Reduction of mass reduction is given a primordial focus in automotive manufacturing sector due to its direct influence on the overall performance and fuel efficiency of the vehicle. Minimization of mass renders least vertical and longitudinal roll motion of ATVs. It plays a crucial role in minimizing the vertical and roll motion of the vehicle. Current work focuses in designing and modifying the knuckle for achieving the same magnitude of forces with reduced mass and without compromising the strength as the component is primarily responsible for reduced fuel consumption and enhanced vehicle efficiency. Hence, the optimization in design of knuckleis to be carried out to render maximum performance coupled withhigh necessity of weight reduction. Shape optimization was carried over in ANSYS Workbench, whose objective function is to reduce weight, in order to save the material resource.The vehicle consists of various physical components which support smooth operation and ensure the safety running during off road conditions.

Suppressed Light Emission of the Reaction Zone in Detonation
THE detonation of high explosives in water can be photographed with an open camera and a flash light as the explosive gases do not emit light. The method has been used1 to investigate the spread of shock waves and explosive gases, and to investigate the initiation by shock waves2. We have found that it can be used also in certain gases such as butane and propane. The method is not suitable, on the other hand, for explosives with two levels of detonation velocity in the case of low velocity. A great part of the reaction then occurs after the reaction zone has passed and the expanding explosive gases are very luminous even in water.
