Spring life suggestion design concept

Under normal use conditions, the spring can still maintain its basic functions after a certain load of the specified number of times under a certain load. The length of the spring life depends on multiple factors, including materials, shapes, size, manufacturing process, conditions of use.

Material

The strength, plasticity, and fatigue strength of the spring material is an important factor affecting the life of the spring. Generally speaking, the higher the strength, the better the plasticity, and the higher the fatigue strength, the longer the life of the spring.

shape

The shape of the spring also has a certain impact on its life. Generally speaking, the more coils, the longer the coil, the longer the life.

size

Manufacturing process

The manufacturing process of spring also affects its life span. Generally speaking, the longer the spring of the manufacturing process and the good surface quality, the longer the life span.

Conditions of Use

The use of spring also affects its life span. Generally speaking, the higher the spring temperature, the greater the vibration, and the stronger the impact, the shorter the life.

Calculation of spring life

There are many calculation methods for spring life, and the commonly used are:

• Standard life method: The number of cycles that spring can be completed under a certain load based on the fatigue intensity of the spring material can be completed.
• Fatigue Life Law: The number of cycles that can be completed according to the actual working conditions of the spring can be completed.

Extension of spring life

The life of the spring can be extended by the following methods:

• Use the appropriate material.
• Reasonably design the shape and size of the spring.
• Improve the level of manufacturing technology.
• Improve the conditions of use.

The life of the spring is an important consideration in the spring design and use. In the process of spring design and use, pay attention to selecting appropriate materials, reasonable design shapes and sizes, improve the manufacturing process level, and improve the conditions of use to extend the life of the spring.
