Abstract

Although a shock absorber in automotive application consists of several parts, there are only a few most relevant for handling axial misuse and extreme loads. Among these, the lower connection to the steering knuckle, often referred to as the yoke or clevis, offers significant design freedom but presents challenges in terms of structural integrity. This presentation focuses on an iterative topology optimization approach utilizing Tosca Structure’s controller-based optimality criteria approach in combination with Abaqus’s capabilities to determine nonlinear buckling loads. The study examines an exemplary design space for a damper yoke, limited on a forged steel or aluminum design and therefore addresses appropriate manufacturing restrictions. The demonstrated workflow provides a fast way of obtaining an initial design, enabling informed decisions regarding weight and cost considerations, material selection, and laying a foundation for subsequent CAD processing or further CAE-based development steps.
