Design and Analysis of Wave Spring and compared with Coiled Spring for same Parameter

Mechanical Engineering

The Spring which is one of the part of Suspension systems, Which is designed mechanically to handle shock impulse and dissipate kinetic energy. It decrease the amplitude of disturbances leading to increase in comfort and improved ride quality. The spring is compressed rapidly when the load impacting on it. The compressed spring rebound to its normal dimension or normal loaded length. The spring get compressed below its normal height when the load pushes the spring down. This causes the spring to rebound again. The spring bouncing process occurs over and over every less each time, until the up-and- down movement finally stops or the disturbance can be neglected. The system handling becomes very difficult and leads to uncomfortable operation when vibration become uncontrolled. Hence, the designing of spring in a suspension system is very crucial. The analysis is done by considering bike mass, loads, and no of persons seated on bike. Comparison is done by substituting coil spring by wave spring to verify the best dimension for the wave spring in shock absorber. Modeling and Analysis is done using Pro/ENGINEER and ANSYS respectively.
