摘  要:以乘用车205/55R16轮胎为研究对象,通过试验研究轮胎力传递率与轮胎空腔共振噪声关联关系。提出用轮胎力传递率幅值高低表征轮胎共振空腔噪声强弱;采用有限元方法建立轮胎力传递率仿真模型,指出多孔吸声材料的力学参数比其自身吸声系数对降噪效果影响更为显著;进而采用最优拉丁超立方试验方法、Kriging近似模型,探究多孔吸声材料的密度、弹性模量、宽度和厚度等4个参数对轮胎力传递率幅值的影响规律,借助多岛遗传优化算法获得多孔吸声材料最优设计参数,通过对多孔吸声材料宽度的轮胎力传递试验和跌落噪声试验验证了宽度参数影响规律的准确性。研究结果表明,相比于原始轮胎,带有优化后的多孔吸声材料的轮胎力传递率幅值明显降低,意味着轮胎空腔共振噪声也会得到有效改善。A passenger car tire 205/55R16 is taken as the research object,and the relationship between tire force transmissibility and tire cavity resonance noise is studied through experiments.It is proposed that the amplitude of tire force transmissibility has the ability of representing the level of tire resonance cavity noise.A tire force transmissibility simulation model with sound-absorbing material is established using finite element method,and it is found that the mechanical parameters of porous sound-absorbing material have more significant influence on the noise reduction effect than the sound absorption coefficient.The optimal Latin hypercube test method and the Kriging approximate model are selected to explore the influences of the density,elastic modulus,width and thickness of the porous material's on the amplitude of the tire force transmissibility,and the multi-island genetic optimization algorithm is chosen to optimize the above four parameters of the porous material.By changing the single width parameter of the porous material,the accuracy of the simulation results is verified through the tire force transmission test and the falling noise test.The results show that compared with the original tire,the amplitude of tire force transmissibility of the optimized tire is significantly reduced,and the cavity resonance noise of the tire is also effectively improved.
