Abstract

This thesis focuses on the structural optimization of DHIL actuators using topology method. Structural optimization aims to enhance the performance and efficiency of structures by refining the shapes and materials. The primary goal is to determine the best possible configuration that minimizes the objective function and satisfies a set of constraints. This study employs an evolutionary structural optimization method, improving the solution quality by avoiding potential kinematic instabilities and including local error estimators. The research involves a detailed analysis of various types of structural optimization, including topology optimization, which is particularly emphasized. The topology optimization technique used in this study intelligently distributes material within a design domain to achieve optimal structural performance under specified load conditions and constraints. Applications of this optimization method span across industries such as automotive, aerospace, and civil engineering. This thesis presents the design, analysis, and optimization processes, culminating in a structurally optimized DHIL actuator model that demonstrates significant performance improvements and material efficiency.
