Variable Force Spring: Features, Working Principle and Advantages

source:Qianye Precision time:2024-8-24

1. Unique Features of Variable Force Spring

Variable force spring, as a type of spring that adjusts its own shape and elastic characteristics according to the change of external force applied, has the remarkable characteristic of its stiffness variability. This spring adapts to different load conditions by deformation, thereby providing appropriate force output under different working conditions. The design of the variable force spring is based on the openness of its coil over its entire length, so that the change in diameter can directly reflect the change in force. When the product is loaded into the display device, the spring will increase its stiffness accordingly, and when the product is removed and pushed forward, the stiffness of the spring will decrease. This characteristic enables the variable force spring to show excellent performance in many occasions.

2. Working Principle of Variable Force Spring

The working principle of the variable force spring mainly involves the relationship between the deformation and force of the spring and the elastic return force. When an external force is applied to the spring, the spring will deform, and the amount of deformation is proportional to the amount of force. This deformation is due to the change in the atomic structure inside the spring, which causes the atomic spacing to change, thereby changing the stiffness of the spring. When the external force is removed, the spring returns to its original state and generates a reaction force equal to the external force but in the opposite direction, which is the elastic restoring force. The elastic return force of the spring is an important basis for its operation and the key to achieving force control.

In addition, the dynamic characteristics of the variable force spring are also an important part of its working principle. When the frequency of the external force is high, the vibration frequency of the spring also increases correspondingly due to the influence of the mass and stiffness of the spring on the vibration frequency. This characteristic enables the variable force spring to maintain stable performance under dynamic load conditions.

3. Advantages of Variable Force Spring

Strong adaptability: The variable force spring can adjust its stiffness according to the changes in external force, so it can adapt to the needs under different working conditions. This adaptability enables the variable force spring to achieve excellent performance in various mechanical devices.

Precise control: Through precise design and manufacturing, the variable force spring can achieve precise control of the spring stiffness to meet the requirements of specific applications. For example, in electric roller blinds, the precise control of the variable force spring allows the curtain to stop and hover at any position, achieving the effect of free positioning and free pause.

High flexibility: Variable force springs can provide different force outputs under different working conditions, making the equipment more flexible when dealing with different loads or working environments. This flexibility allows variable force springs to show their unique advantages in a variety of situations.

In summary, variable force springs play an important role in machinery and engineering with their unique characteristics, operating principles and advantages. Through continuous research and innovation, the performance of variable force springs will be further improved to provide more excellent solutions for various mechanical equipment.
