This project presents a comprehensive design of a hydraulic actuator system, addressing specific requirements and guidelines. The report begins with an introduction to hydraulic actuators, their applications in various industries, and the overall arrangement of the actuator components, including the cylinder, piston, spring, and hydraulic lines. Key design features are discussed, emphasizing factors like cylinder selection, material choices (Titanium, Ductile Iron), and the importance of considering operational conditions. The project includes detailed calculations for loading and performance, alongside a one-page summary and a 2D drawing of the actuator design. The conclusion highlights the successful development of the initial design, the design calculations, material selection, and the inclusion of a 2D design drawing. The project also includes references to support the design choices and analysis.
