Working principle of excavator solar container device complete design scheme

Why is the design process of excavators so complicated?

Owing to the symmetry of the working device structure and computational complexity, the lightweight design process was simplified by including only the thickness of the top plate, bottom plate, and left plate of the boom as design variables. The stress situation of excavators during actual operation is very complex.

What are the design principles for hydraulic excavator working device?

Design principles for hydraulic excavator working device In doing anything, it involves methodology. Similarly, there are certain principles and requirements in carrying out structural design. Because the hydraulic excavator often starts frequently, brakes, changes the shock, therefore has the high design request to the working device. 3.1.

What is a finite element model of excavator?

A finite element model of the whole excavator has been developed in this paper. A stress test experiment of excavator under the selected represent working condition has been conducted. Based on the validated model presented in this paper, the boom structure has been optimized.

What is a solid finite element model of an excavator bucket?

Sarkar et al. developed a solid finite element model (FEM) of an excavator bucket made of alloy by using the software CATIA v5 and ANSYS Workbench. Based on the assumptions that bush is defined as a fixed component and the load is applied on teeth, static analysis was carried out.

How to improve the structure of existing excavators?

To improve the structure of existing excavators, this paper focuses on the lightweight design of their working devices. Currently, structural size optimization mainly relies on two methods: one is based on high-precision simulation models.

How is the excavator model built in Dymola?

The excavator model, as shown in Fig. 1, is built in Dymola through mechanical-hydraulic integration modelling. The degrees of freedom, constraint, and mass properties are defined in the mechanical system. The bucket is operated by the movement of three hydraulic actuators, including arm, bucket, and boom cylinders.
