Helical Spring Testing Machine
Approx. component budget: Rs. 6,000 - 10,000
Objective
Measure spring stiffness for different wire diameters, coil diameters and materials and compare it with the design formula.
What you will build
A frame with a screw or lever loading arm, a load cell or calibrated weights, a dial gauge for deflection, and holders for springs of different wire sizes.
Results you can expect
- Load vs deflection curves
- Measured vs calculated stiffness
- Shear stress and Wahl factor check
- Effect of number of coils
What you will learn
Spring design, stiffness, stress and testing, used everywhere from vehicles to furniture.
Tools and notes
Dial gauge, load cell or weights, Excel. Stay within the elastic limit and hold springs so they cannot fly out.
Resume points from this project
- Built and tested Helical Spring Testing Machine; objective: measure spring stiffness for different wire diameters, coil diameters and materials and compare it with the design formula.
- Measured and analysed load vs deflection curves and measured vs calculated stiffness; wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
