Brief introduction to Spring design

Hooke's Law is a fundamental principle in mechanics.
However, it is important to note that there are non-linear springs, where the resisting force is not linearly proportional to the displacement.
There are various types of springs, and the most abundant ones are illustrated below.
Circular cross section springs are depicted in the illustration.
Leaf springs, as shown in the diagram below in a common wheeled-vehicle scenario, can be engineered to possess progressive spring rates.
The history of springs dates back to the Bronze Age, where metal springs were already in existence.

A team from West Lake University has prepared a new type of fiber optic spring sensor that may be used to discover microphysical phenomena

A spring balance is a macro-scale dynamometer, which is often used by people to weigh various fruits, vegetables, commodities, etc. If the size is reduced to the micro-nano scale, is it possible to "weigh" tiny forces in a calibrated way like a spring balance?



This requires significantly reducing the detection limit of the sensor, which places extremely high requirements on the precision of the device. In previous studies, scientists often solved this problem by optimizing the mechanical properties of the structure
Recently, a team from West Lake University and the Hangzhou Institute of Advanced Studies of the National University of Science and Technology of China collaborated to create a new type of optical fiber spring sensor from the perspective of optimizing the processing technology.

In-depth research on the automotive air suspension industry: Suspension technology innovation, air suspension is in the ascendant

The automobile suspension is an important force transmission connection device between the body and the wheels.



Car suspension is the connection device between the car body (frame) and the wheels. Its main function is to transmit the torque between the car body and the wheels, such as support force, braking force and steering force, and to reduce the impact of rough roads on the car body. Absorbs vibrations caused by wheel movement, ensuring car riding comfort and reducing losses in cargo transportation. Usually the automobile suspension structure consists of elastic elements, shock absorbers and guide mechanisms. These three parts play the roles of buffering vibration, absorbing vibration and transmitting torque respectively.



Elastic elements and shock absorbers together constitute the suspension damping system and are the most important components in the automobile suspension system. The elastic element has a certain buffering effect, which can extend the impact time, reduce the force per unit time, and achieve a buffering effect. The shock absorber can absorb energy, convert the kinetic energy of the impact into heat energy, and consume the excess vibration, thereby achieving the vibration reduction effect. The elastic element and the shock absorber are generally placed in parallel. During the compression and rebound process of the elastic element, the shock absorber absorbs energy at the same time. After that, the elastic element returns to its original length and supports the vehicle to its normal height.

The magical spring suspension phenomenon reveals the secret of "anti-gravity" hidden in springs



The spring levitation phenomenon is a magical physical phenomenon. Its appearance seems to challenge the law of gravity and has attracted widespread attention from scientists and physicists. This phenomenon allows us to re-examine the properties of springs, a common object, and reveals the surprising "anti-gravity" secrets they contain. In this article, we’ll delve into the fundamentals of spring levitation, explain how it works, and explore its applications in a variety of fields. Through clear organization and detailed information, we will reveal the inner workings of this wonderful phenomenon and its potential for scientific research and real life.





A spring, usually a wire made of metal or plastic, has excellent elastic properties. When an external force acts on the spring, it can store elastic potential energy, and when the external force stops acting, the spring returns to its original state. This elastic property is at the heart of the spring suspension phenomenon.



In the following sections, we will explore the basic principles of springs, reveal the working mechanism of the spring levitation phenomenon, and delve into its wide range of applications in maglev trains, high-precision experiments, audio equipment, and industrial production.





Most importantly, we'll explain how spring levitation is related to gravity, providing a thorough explanation of why it doesn't really violate Newton's universal law of gravity. Finally, we will look to the future and demonstrate the future potential and development direction of spring suspension technology.

Wavy springs

Have you ever come across wave springs? Also referred to as coiled wave springs, they are characterized by their unique wavy design. Unlike traditional springs, wave springs do not lie flat when placed on a surface. Instead, their wavy structure causes certain parts of the spring to lift up. Here are five interesting facts about wave springs:

Ceramic springs

Ceramic springs are manufactured using advanced ceramic materials as their primary components. By carefully controlling the composition and structure, these ceramic materials exhibit elasticity, challenging the conventional perception of ceramics as "brittle" and "hard" materials. In addition to meeting the standards of metal springs in terms of compression cycle performance, ceramic springs possess exceptional properties such as high temperature resistance, corrosion resistance, and resistance to water and oxygen.

​

In comparison to metal springs, ceramic springs offer several advantages. While metal springs can only withstand temperatures up to 700°C and cannot operate for extended periods under such conditions, ceramic springs can easily surpass this temperature limit and endure high temperatures exceeding 1400°C. This makes them suitable for applications in aerospace and new energy batteries, where they can bear significant responsibilities in extreme environments characterized by high temperatures, water, oxygen, and corrosive elements. Furthermore, ceramic springs have successfully withstood numerous compression fatigue tests.



Ceramics encompass not only the renowned porcelain that symbolizes traditional Chinese cultural heritage, but also ceramic springs, which introduce elasticity to ceramics. Currently, the highest known record for elastic compression in ceramics stands at 20%.
