Introduction

Design analysis of pancanaka 2000 tooth bucket structure using finite element method. FEM analysis of Pancanaka 2000 tooth bucket structure. Identifies critical stress, displacement, safety factors. Links failure causes to material, wear, and assembly tolerances, crucial for excavator design.

Abstract

This study tests the structural performance of the Pancanaka 2000 tooth bucket, a common heavy-duty excavation component. The goals are to determine the component testing method, analyze the findings of finite element simulation sub-modeling, and identify the causes of structural failure. Shining 3D scanning created a detailed model of the Pancanaka 2000 tooth bucket. ANSYS simulation software performed a Finite Element Analysis on this model. A 10-ton static force was applied to imitate working circumstances on the bucket teeth tip. The simulation monitored mechanical reactions, including total displacement, von Mises stress, and safety factors, which indicate structural reliability. The study found numerous noteworthy findings. First, the computerized model of the bucket teeth allowed for an exact analysis of loading stress. The simulation revealed a region susceptible to failure under high loads, characterized by a maximum total displacement of 0.38883 mm, a maximum von Mises stress of 321.5 MPa, and a minimum safety factor of 1.328. Qualitative analysis identified material as the leading cause of fracture. Wear and scraping were noticed at the bucket tooth-adapter interface. Mechanical failure was also linked to component gaps exceeding design tolerance. These flaws lead to inappropriate load distribution and stress concentration, resulting in structural failure during operation. According to this study, the durability and performance of excavator components, such as the Pancanaka 2000 teeth bucket, depend on correct design, strict material selection, and precise assembly tolerances.

Review

This study presents a practical and relevant analysis of the Pancanaka 2000 tooth bucket's structural performance, employing the Finite Element Method (FEM) to diagnose potential failure mechanisms. The clear objectives, encompassing component testing methodology, FEM sub-modeling analysis, and failure identification, are well-articulated in the abstract. The integration of Shining 3D scanning for accurate model generation before subjecting it to ANSYS FEM with a simulated 10-ton static load demonstrates a robust approach to evaluating a critical heavy-duty excavation component. This work holds significant industrial relevance, offering insights crucial for improving the durability and operational reliability of such equipment. The abstract effectively highlights several key strengths and findings. The FEM analysis successfully identified a critical region of failure characterized by quantitative metrics: a maximum total displacement of 0.38883 mm, a maximum von Mises stress of 321.5 MPa, and a minimum safety factor of 1.328. Furthermore, the qualitative analysis points to specific root causes of failure, including material deficiencies, wear/scraping at interfaces, and component gaps exceeding design tolerances, leading to poor load distribution and stress concentration. These detailed findings provide valuable actionable intelligence for manufacturers and operators alike, offering a foundation for targeted improvements in design and manufacturing processes. While the abstract provides a strong overview, a few areas could enhance the full paper's impact and comprehensive nature. The abstract mentions "material as the leading cause of fracture," but specific details about the material properties used in the FEM simulation, or suggestions for improved material selection, are not elaborated upon, which would be crucial for a "design analysis." Additionally, the absence of any mention of experimental validation for the simulation results is a notable point; correlating simulation findings with physical tests, even destructive ones on failed components, would significantly bolster the confidence in the identified failure mechanisms. Finally, while the analysis identifies flaws, the "Design Analysis" aspect implied by the title could be further strengthened by discussing how these findings could specifically inform new design iterations or optimization strategies, moving beyond general conclusions about "correct design, strict material selection, and precise assembly tolerances."
