How to Make A Spring Stronger or Weaker?

When designing the spring force, we often need to adjust the spring force to make the spring stronger or weaker. So how can I adjust the spring elements to achieve the desired elastic effect?

• Make the compression spring stronger

If you want to make the spring stronger by adjusting the outer diameter, you can make the outer diameter of the compression spring smaller when the wire diameter remains the same. If you want to weaken the spring force, you must make the outer diameter or inner diameter of the spring larger. If the coil is tighter, you will have a smaller index, which will give you more power. If the coil diameter becomes larger, the spring index becomes larger, which makes the spring weaker. This caused by the elasticity of the spring. A spring with a smaller spring coefficient can withstａnd more stress than a spring with a larger spring coefficient. Therefore, if the diameter of the spring is reduced or the wire diameter of the spring is increased, the spring will be stronger, and the compression force borne by the spring will become greater.

If you want to make your spring more applicable, you need to adjust it in various places, so that you can not only get the right force, but also get the right travel. You can also change the spring force by increasing or decreasing the coil. When you increase the coil, the pitch of the compression spring becomes smaller. If you reduce the coil, the pitch of the spring becomes larger, which means that the coil compression stroke becomes longer. For tension springs and torsion springs, if the coil is reduced, the spring will also be stronger, but it will bear greater stress. If the coil is added, the tension and torsion springs will have more coils working together to provide the appropriate spring force.

• Make the tension spring stronger

You can get the correct spring through these adjustments. For compression springs, it must be ensured that the actual maximum travel of the spring is higher than the maximum travel considering the height of the body. This will increase the spring length, so the compressed stroke becomes longer to meet the required load height. If it is a tension spring, the length of the pull hook must be shortened, which will also affect the length of the spring. Therefore, be very careful when taking out the coil. For torsion springs, the free position must be adjusted further away from the direction of travel in order to produce greater torque through greater travel.
