Modal analysis of polymer composite based leaf spring by additive layer manufacturing using FEA method

Leaf spring is a basic type of spring, often used for suspension in wheelchairs. In addition it is probably the most established form of spring, going back to the past. In this worksheet, the spring of CAD depicts the development of a solid edge system and the re production carried out in the ANSYS systems through continuous testing and similar investigations. Spring E-Glass - the mean direction of the spring-blade of the expert leaf at 4000 N is 14.85 mm. The maximum frequency is 548.97 Hz. The reason for the vibration from the recurrence level is therefore significantly comparing to the carbon fiber properties. The avoidance of the avoidance is 13.48 mm which is very low with a recurrence decrease 538.32 Hz. which is also very low and this item can support a lot like traditional spring materials but the thing is good in terms of weight because Carbon fiber does not weigh to him iron 35% weight is reduced by E - Glass materials. This work revolves around the use of polymer composite based leaf spring by additive layer manufacturing using FEA method bases on thermoplastic polyimide with 30% carbon fiber reinforced (composite material) by removing the En 45 metal from the common leaf sources of the suspension system to reduce the weight of the object, improve safety, comfort and durability.
