“…Understanding the excavation process is a vital aspect and focus of excavator research. In a similar study, Mughal et al [66] performed finite element analysis on various excavator bucket models with different geometric parameters, including bucket curvature, using ANSYS. They determined the stresses and strains in their models and calculated the maximum values of Von Mises stress, principal stress, factor of safety, and total deformation.…”

Construction machinery, which is widely used in infrastructure construction, is growing rapidly all over the word. However, the complex working conditions of construction machinery lead to serious wear, particularly the wear of the bucket teeth on construction machinery. To control the wear procedure, it is essential to understand the wear mechanism and identify the wear form under variable working conditions. The modeling methods of bucket tooth wear with different wear mechanisms were reviewed. The modeling methods were divided into the analytical method and the numerical simulation method. The numerical simulation method included the discrete element method, finite element method, SPH method, and so on, which were used to simulate the bucket digging process and analyze the interaction between the material and bucket teeth during the working process. This enabled a force analysis of the bucket digging process and the identification of the location of maximum wear. By establishing a wear model, it is possible to better understand and address the wear problem in construction machinery. This article aims to summarize research methods concerning the wear of wear parts in construction machinery. It provides a theoretical foundation for future investigations in this area and aims to address challenges such as lengthy wear life testing, numerous interfering factors, and the difficulty of data collection pertaining to wear parts.

“…The 3D solid model of the working device of the hydraulic excavator was established in Solidworks software, which was imported into Ansys Workbench in the format of intermediate data.x_t to establish the finite element model [4]. Before the modal analysis, the model is simplified and cleaned to remove the geometric features such as threaded holes, rounded corners and chamferes, which have little influence on the analysis results, so as to increase the calculation accuracy and efficiency of the simulation [5].…”

For the sake of analyze the dynamic characteristics of the working device of the hydraulic excavator, a three-dimensional model of the working device of a certain type of hydraulic excavator is established, and its four typical working conditions are determined. The finite element model of the working device is established, and the first six natural frequencies and main modal forms of the working device of the hydraulic excavator under four working conditions are calculated, which provides a basis for optimizing the dynamic characteristics of the working device of the hydraulic excavator.
