Human power generation in space Rutgers symposium on lunar settlement

Introduction

Assuming 40% of a 2000 Calorie/day diet is used for physical activity, 
3.35 MJ of energy/day is used to perform activities.
Approximate mechanical energy performed during some physical activities:
Walking/Running (0.49 J/kg*step)
Stair climbing (1.96 J/kg*step)
Cycling (88.2 J/rev)
Lifting (9.8 J/kg*m) ....etc

In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers in the present scenario. Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The suspension leaf spring is one of the potential items for weight reduction in automobiles as it accounts for 10% - 20% of the unsprung weight. This achieves the vehicle with more fuel efficiency and improved riding qualities.

Optimizing design of spring using genetic algorithm

Abstract:
This paper deals with the elaborate designed optimization technique
of coil spring sets. Attention is focused reducing the weight and
stresses are calculated keeping in to considerations the various
critical points. Graphical optimization the various critical points
graphical optimization technique is used for non-linear programming
.Maximum endurance shear stresses spring constant etc.. are taken as
the objective function also we have mainly ....etc

Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

ABSTRACT

The holddown Spring is one of the major components of a fuel assembly for PWR. It holds the fuel assembly firmly seated down on the lower core plate and allows the FA axial movement caused from the irradiation growth of guide thimbles. Depending on the up-lift force of a fuel assembly, from 2 to 4 leaves are assembled to be a set of a spring pack and it is fixed on the frame of the top end piece by screw. The spring can deflect so greatly during operat ....etc

ABSTRACT
The subject gives a brief look on the suitability of composite leaf spring on vehicles and their advantages. Efforts have been made to reduce the cost of composite leaf spring to that of steel leaf spring. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very replacement material for convectional steel. Material and manufacturing process are selected upon on the cost and strength factor. The design method is selected on the basis of mass production.
