Abstract In our project we want to create an

umbrella which can automatically (close ,open) by a hydraullic system that depends on solar energy and this system can help to shading a huge area ,and it can help to collect the rain water

The umbrella surface has a special rain water collection the shape slope down toward the center allowing rain water to be naturally collected the water flow down through the umbrella column

Aims of project It’s a shading system that dramatically

lower a temperature

protection from sun radiation

protection of rain water and help in water harvesting .

Mechanism of umbrella :

Steps of project

Position analysis for all links.

Velocity analysis

acceleration analysis

dynamic analysis for all links

Analysis for all forces that acts at links

Analysis for shear stresses

Analysis the bending moments

Selection for the material ,cross section and thickness

SUMMARY

It is the main object of the

present project to provide an

automatic umbrella control

mechanism, which open at

the day and close at night

by a light sensors.
