Abstract: The performance and efficiency of hydraulic excavators heavily depend on the design and optimization of their working devices. The working device, which consists of the boom, arm, and bucket, plays a crucial role in determining the machine's digging capacity, stability, and overall operational efficiency. This paper presents a comprehensive study on the dynamics simulation and optimization of hydraulic excavator working devices. The paper outlines the fundamental principles of dynamic modeling, incorporating multi-body dynamics and hydraulic system analysis. It further explores various simulation techniques to evaluate the performance of the working device under varying operational conditions, including load and hydraulic system effects. The study also addresses performance optimization, focusing on multi-objective optimization methods that balance multiple factors such as energy efficiency, speed, and load capacity. Additionally, the paper discusses key factors influencing performance, such as mechanical design, material properties, and operational conditions. The results of the dynamic simulations and optimization analyses demonstrate potential improvements in operational efficiency and system stability, providing a valuable framework for the design and enhancement of hydraulic excavator working devices.
