Investigation of Impact Properties of Wave Springs Designed for Additive Manufacturing /

By Ahmed, Faizan . . 119p. , Innovation continues to transform various fields, including the design of springs. Initially helical springs were used as compression springs for most of the applications. However, the design innovation has led to the introduction of a new type of compression spring which is the wave spring. At the same time the advancements in manufacturing technologies are reshaping the production methods. Traditional manufacturing methods are gradually being replaced with additive manufacturing. Because AM has the ability to fabricate complex geometries with high precision and minimal material waste. These advantages make AM a key driver of innovation in modern design and engineering. Wave springs possess better mechanical properties as compared to helical springs, as highlighted by previous studies. But previous studies are limited to only compression analysis of wave springs at slow speeds. The behavior of this newly developed spring is unknown for sudden high speed impact loadings. This research involves the experimental and computational analysis of six different geometries of wave spring under the high speed loading conditions of 17mm/sec. The six geometries of wave springs are fabricated using FDM technology. PLA material was considered for the fabrication due to its availability and compatibility with the FDM. The other 2 materials including spring steel, and TPU (Thermoplastic Polyurethane) were used in computational modelling only. The results mainly showed that the material properties had a greater influence over the geometric parameters. PLA due to its brittle nature resulted in formation of local stresses that minimized the performance parameters of all geometries of wave springs. Spring steel having high elasticity and compressive strength showed better impact properties unlike PLA. TPU although elastic but moderate compressive strength was not able to show impact properties like spring steel, but due to its elasticity, it was a better choice over PLA. Each of the 6 geometries had different configurations that resulted in different local stress formations and thus different energy absorption, stiffness, and load-bearing capacity. To apply the concept of wave spring to real-engineering world, multiple wave spring designs were integrated in the car suspension system and analyzed on MSC Adams (Automated Dynamic Analysis of Mechanical Systems) for their energy absorption, stiffness, and maximum load bearing capacity. This analysis further validated the initial results and provided a gateway to the innovation in the car suspension system design and analysis. 30cm.
