The principle of compound bow energy storage

Do compound bows store the most energy?

Clearly there are many factors, bow design being dominant, but surely this value can be calculated. It appears that compound bows store the most energy, but how much is actually stored? You can draw the bow with force meter, noting the force at set intervals of distance.

How does a compound bow work?

The speed and power of the arrow are directly influenced by the efficiency of the bow’s mechanism, including the limbs, cams, and bowstring. A well-tuned compound bow can deliver exceptional energy transfer and impressive arrow velocity. Compound bows feature various types of cams, each offering distinct advantages.

How do bows work?

Basically, bows work like big, weirdly shaped springs, which are great devices for storing potential energy. When you pull back the bowstring, it bends the limbs of the bow, storing most of the energy your arm and back muscles produce in the limbs themselves. If you hold the bowstring drawn back, this energy remains stored in the limbs.

What are the limbs of a compound bow?

The limbs are the flexible part of the compound bow, which stores the energy of the bow. These limbs are often made from carbon fiber or other composite materials. When you draw back the bow, the limbs will compress, therefore all the draw weight comes from the limbs. Compound bows have 1 string and 2 cables.

How does a recurve bow work?

Recurve bows are relatively simple to understand. The limbs store the energy which is propelled into the arrow when you release the string. But how does a compound bow work? The let-off of a compound bow almost seems magical. How can the draw weight of a compound bow decrease at the near end?

What is the power stroke of a compound bow?

The power stroke of a compound bow refers to the distance the bowstring travels from its resting position to the point of full draw. It determines the energy stored in the bow and directly affects the arrow’s velocity. A longer power stroke allows for more energy storage and can result in increased arrow speed and impact.
