Tiivistelmä
The purpose of the master's thesis is to build a simulation model that combines hydraulic and mechanical systems for a semi-autonomous electric excavator. The model's mechanical section includes important parts, for example the Main Boom, Dipper Arm, Bucket, and Dozer Blade, all of which are connected to different cylinders in a proper way. The hydraulic circuit, which is essential to the functioning of the excavator, has been particularly made in the Mevea environment, integrating hydraulic elements for making systematic modeling.
Starting with the specific electric VOLVO ECR 25 model, the work begins with Computer-Aided Design (CAD) modeling of the excavator using SolidWorks. By providing a user-friendly interface and a mate controller function that makes it easier to understand the excavator's kinematic model, SolidWorks plays an important role in making the CAD modeling process. SolidWorks' Assembly section is used to well-construct each carefully developed component of the excavator one at a time.
Moreover, the platform used to create the excavator simulation model is Mevea, which is well-known for its real-time physics-based simulation capabilities. The simulation model is carefully created in the Mevea Modeler environment by utilizing helpful CAD model data. The Mevea solver is used to simulate the model thoroughly after the hydraulic circuit design.
This thesis highlights how to build a comprehensive simulation model for a semi-autonomous electric excavator by combining CAD modeling in SolidWorks with simulation development in Mevea. By means of complex design and simulation procedures, this study advances the technology of excavators and opens the door to increased productivity and efficacy in excavation work.
