How to Choose the Right Spring? Comprehensive Guide
Which Spring Type Do You Need?
Choosing the right spring in engineering projects is the first step for the efficient operation of the mechanism. Here are selection criteria according to spring types:
- Compression Springs: Resist compressive force. They are the most common type. Used in shock absorbers, valves, and buttons.
- Extension Springs: Resist stretching. They have hooks at their ends. Seen in trampolines and garage doors.
- Torsion Springs: Store rotational force (torque). Latches and door handles are examples.
Parameters to Consider
- Spring Diameter (D): The outer diameter of the spring must be suitable for the mounting slot.
- Wire Diameter (d): As wire thickness increases, the stiffness (rate) of the spring increases.
- Free Length (L0): The length of the spring without load.
