Mechanical energy storage system

Figure 5. The table of the efficiency

Antons Prokopenko, Andrii Semenov, Ingmar Jans

Introduction

ASA 2014

Results

Conclusion

Due to the problems which were mentioned before we obtain the following result

The general target was to build a mechanical energy storage system.The challenge was to build the prototype based on the another group's design. The design could be improved, if it would follow certain criterions:

  • To increase efficiency level
  • To make easier for the consumer usage

The prototype is only a proof of concept. The efficiency is poor due to big losses in the transmission, and due to the multiple transitions of energy. Also, system's output is not regulated in a proper way to get a good level of efficiency.

Questions?

The original idea

Our design

The original design was based on a flywheel rotation and a linear spring compression. To compress spring the worm gear would be used.

Figure 4. The efficiency graph

For our design we used a clock spring that was directly connected to a motor. This improvement decreased energy loss in the system. The flywheel was changed on a rubber band, which gave us some advantages as well as disadvantages. We also came up with the efficient blocking system which was able to save collected energy .

Сontrolling process

During our project we faced the problem that we cannot control the speed of the energy release. This issue should be take into account.
