Review of the Modeling Methods of Bucket Tooth Wear for Construction Machinery

Abstract

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.

Machine Learning-Based Shoveling Trajectory Optimization of Wheel Loader for Fuel Consumption Reduction

“…For the age of the wheel loader, it is sure that with the increase in use time, there will be different degrees of wear between the mechanisms, and fuel efficiency will be reduced. In particular, the bucket tip of the bucket, as the part that contacts the pile, suffers the most wear during the long-term shoveling process [46]. Timely replacement or repair of bucket tips is an effective way to reduce fuel consumption.…”

Abrasive Wear Properties of Wear-Resistant Coating on Bucket Teeth Assessed Using a Dry Sand Rubber Wheel Tester

“…Bucket teeth, which are typically positioned at the forefront of an excavator, are highly susceptible to significant and intricate wear because of the direct contact with ores, gravel, and other materials [1][2][3][4]. Their wear failure will reduce productivity and increase equipment downtime, resulting in considerable economic costs [3].…”

“…Their wear failure will reduce productivity and increase equipment downtime, resulting in considerable economic costs [3]. The usual wear failure forms of bucket teeth include impact, abrasion, chemical action, and fretting [1]. The most common type of wear in bucket teeth is considered to be abrasive wear, which occupies a significant portion of overall wear.…”
