摘要
针对矿用溜槽的振动及噪声剧烈、使用寿命低等问题,设计一种钢‑泡沫铝‑钢层合结构矿用溜槽。采用参数优化理论,结合ANSYS Workbench软件对其结构参数进行优化设计。分析了优化后的钢‑泡沫铝‑钢层合结构矿用溜槽的抗冲击性能、谐响应性能及声学性能。结果表明:钢‑泡沫铝‑钢层合结构矿用溜槽不仅质量降低11.4%,而且最大冲击应力降低15%、最大谐响应振幅降低90%以上,同时溜槽的降噪性能也得到显著提升。证明了钢‑泡沫铝‑钢层合结构矿用溜槽不仅能够减轻溜槽的质量而且具有优越的抗冲击和减振降噪性能。
A kind of mine chute with steel-aluminum foam-steel laminated structure is designed to solve the problems of severe vibration and noise and low service life.The structural parameters of the aluminum foam mine chute are optimized using parameter optimization theory and ANSYS Workbench software.The impact properties,harmonic response performance and acoustic performance of the optimized aluminum foam mine chute are analyzed.The results show that the aluminum foam mine chute not only reduces the mass by 11.4%,but also reduces the maximum impact stress by 15%and the maximum harmonic response amplitude by more than 90%,and the noise reduction performance of the mine chute is also significantly improved.
