3D Modeling Simulation and Innovative Design of a Saw Cutting Mechanism for a Movable Buckling Machine
Abstract
:1. Introduction
2. Materials and Methods
2.1. Materials
2.1.1. A36 Steel
- Strength Differential: While the yield and tensile strengths of A36 steel suffice for general structural requirements, they are comparatively lower than those of Q345. Under extreme cold conditions, the material’s properties may further deteriorate, leading to inadequate stability of the sawing mechanism under heavy loads and posing potential safety hazards.
- Toughness Issue: A36 steel exhibits poor impact toughness at low temperatures, rendering it more susceptible to brittle fracture. This is a non-negligible drawback for sawing mechanisms that frequently operate in cold environments. In contrast, Q345 maintains good toughness even at low temperatures, effectively preventing the occurrence of brittle fracture.
- Corrosion Resistance: A36 steel possesses relatively weak corrosion resistance, making it vulnerable to corrosion in wet or salty cold environments, which can subsequently shorten its service life. In contrast, Q345, with its superior corrosion resistance, is better suited to withstand harsh working conditions.
2.1.2. 6061-T6 Aluminum Alloy
- 4.
- Strength and Rigidity: While aluminum alloys exhibit a high specific strength (ratio of strength to weight), their absolute strength, such as yield strength and tensile strength, is generally lower than that of Q345. During sawing processes, particularly when dealing with hard materials or requiring high stability, aluminum alloys may not meet the necessary requirements.
- 5.
- Low-Temperature Performance: Although aluminum alloys do not become extremely brittle at low temperatures like some metals, they still exhibit a notable decrease in strength as the temperature drops. In contrast, Q345 maintains relatively high strength and toughness even at low temperatures, making it more suitable for operational demands in cold climates.
- 6.
- Wear Resistance: Sawing mechanisms frequently come into contact with materials during operation, leading to wear and tear. Aluminum alloys possess relatively poor wear resistance, which may result in faster wear and more frequent maintenance requirements. In contrast, Q345 exhibits better wear resistance, contributing to the extended service life of sawing mechanisms.
