摘　　要：针对于内燃叉车工作中的噪声问题,通过分析内燃叉车噪声的组成部分和产生机理,提出了相应的降噪措施,特别针对于内燃叉车发动机的噪声进行了实验测试,提出了一种基于多种材料组合的降噪措施,并通过实验验证了该种材料组合降低发动机的噪声水平,实验结果表明,该种材料组合可以有效地降低内燃叉车发动机噪声的40%~50%,从而降低内燃叉车的整体噪声水平。Aiming at the noise problem in the operation of internal combustion forklift,the components and mechanism of the internal combustion forklift noise are analyzed,and the corresponding noise reduction measures are proposed.The noise of the internal combustion forklift engine is tested experimentally.The noise reduction method of the material combination is verified by experiments to reduce the noise level of the engine.The experimental results show that the material combination can effectively reduce the engine noise of the internal combustion forklift and reduce the overall noise level of the internal combustion forklift.
