摘　　要：该文以COMSOL Multiphysics仿真为基础,分别建立了不同几何形状的三维图像,在限制无关变量的情况下,探讨了不同形状的压电陶瓷材料发出电能的大小,为压电道路中压电单元的铺设做了辅助研究。并且做了相关的参数化分析,验证压电陶瓷发电规律随荷载的变化关系研究发现,正八棱柱体在限制其他无关变量的前提下,使用相同体积的压电材料和相同载荷的作用下发出的电能最多。In this paper,based on COMSOL Multiphysics simulation,3D images of different geometric shapes are established respectively.In the circumstance of limiting irrelevant variables,the magnitude of electric energy generated by piezoelectric ceramic materials with different shapes is discussed,which is an auxiliary study for the laying of piezoelectric units in piezoelectric roads.And the relevant parametric analysis was done to verify the relationship between the power generation law of piezoelectric ceramics and the load.The research found that the regular octagonal prism,under the premise of limiting other independent variables,uses the same volume of piezoelectric materials and the same load to generate the most electricity.
