Optimization design of coal crusher based on biomechanics characteristics
Abstract
Background: With the increasing demand for equipment performance in the coal industry, traditional coal crushers face problems such as high vibration, high noise, insufficient wear resistance, and frequent mechanical failures during long-term operation. To this end, the study adopts a combination of biomimetic structural design and multi-layer composite material optimization to improve the performance of coal crushers. Method: Based on biomechanical characteristics, this method optimizes the design of the coal crusher from three aspects: overall results, crushing components, and shock absorption and noise reduction performance, in order to reduce its vibration and noise while maintaining or improving its mechanical strength and wear resistance. Result: The optimized support structure of the coal crusher improved its seismic performance by at least 20% when subjected to impact forces, effectively reducing the concentration of local stress and the occurrence of mechanical failures. The hammer crushing component made of multi-layer composite materials has an HRC hardness of about 67 and an impact toughness of about 15 J/cm3, significantly improving the crushing efficiency and service life of the coal crusher. Conclusion: The optimized coal crusher exhibits excellent performance in vibration control, noise reduction, and wear resistance, providing a more efficient and environmentally friendly coal crushing equipment for the coal mining industry.
