Can mechanical spring systems be used for energy storage in elastic deformations?

Energy storage in elastic deformations in the mechanical domain offers an alternative to the electrical, electrochemical, chemical, and thermal energy storage approaches studied in the recent years. The present paper aims at giving an overview of mechanical spring systems’ potential for energy storage applications.

Can a spring-based mechanical energy storage system be used as a power supply?

However, the spring-based mechanical energy storage system has been rarely used as an active power supply for mechanical systems, largely due to its low energy density (around 0.14 kJ kg −1 or 0.04 Wh kg −1 for steel spring [ 19]) and the additional conversion from mechanical energy to electricity.

Can mechanical spring systems store macroscopic energy?

Mechanical spring systems’ benefits and limits for storing macroscopic amounts of energy will be assessed and their integration with mechanical and electrical power devices will be discussed. 1876-6102 © 2015 The Authors.

Can mechanical springs be used for energy storage?

As far as mechanical energy storage is concerned, in addition to pumped hydroelectric power plants, compressed air energy storage and flywheels which are suitable for large-size and medium-size applications, the latest research has demonstrated that also mechanical springs have potential for energy storage application .

What determines the mechanical energy storage capacity of a spring?

The mechanical energy storage capacity of the spring depends on the elastic deformation of the materials that is correlated with their modulus and yielding strain.

How does a mechanical energy storage device work?

Since the coil spring in the mechanical energy storage device has a certain working limit, and the purpose of using the mechanical energy storage method is to provide an applied torque for starting, as well as playing an auxiliary starting effect, the stored energy is sufficient to assist the vehicle to complete the start.
