About HM Tracker Design

What is this app about? Short introduction

This app presented a new progressive and revolutionary way for optimizing trackers with arbitrary design and geometry. It is based on linear optimization and implemented as a custom-built finite element library. Stress and buckling (lateral and local) validations are performed in conformity to Eurocode EN 1993-1-1 - Design of steel structures. Wind load assumptions are taken from the wind tunnel studies of Peterka and Derickson and applied as non uniform load distributions on the tracker surface. Additional national standards can be considered by setting appropriate safety factors for wind and dead load.

The results of the performed finite element analysis can be used to determine the weight of a heliostat or solar tracker for a given geometrical and environmental boundary condition.

It can assist the work of researchers, design engineers and renewable energy investors or can be used as a convenient and quick-reference manual.
