Problems occur in automobiles when driving bumps on road and insufficient road conditions. This work aims at
improving the performance of the helical coil spring used in hatchback suspension cars via various spring parameters to make it
more powerful than the current hatchbacks. A helical coil spring is used by 4-wheel cars that are part of the Indian automotive
hatchback category. It is noted that due to heavy the weight of the springs and loads on it, the vehicle usually makes a drift over
one side of the road. To omit such problems, the method of redesigning and optimizing is utilized. An optimizing technique well
known as the design of experiments (DOE) is used for current work in ANSYS 18.1 workbench to optimize and omit the current
problems in the helical coil spring. Also, Different materials are being compared to check the suitability and the better material
for coil spring.
