摘　　要：参照一种飞虱若虫后腿锯齿形状,基于傅里叶函数对锯齿齿廓形状进行曲线拟合,设计出一种飞虱仿生齿廓,根据该齿廓设计了仿生齿轮传动机构。利用有限元分析软件对新型仿生齿轮传动机构进行接触应力和传动误差分析,与标准的采用渐开线齿廓的齿轮传动机构进行对比,仿真结果表明:相同载荷前提下,相比渐开线齿廓,该新型仿生齿廓接触强度更好;误差分析表明,采用仿生齿廓传动误差不大于渐开线齿廓。Referring to the sawtooth shape of the hind leg of a planthopper nymph,a kind of simulated tooth profile of the planthopper was designed based on the curve fitting of the serrated tooth profile using Fourier function,and the bionic gear transmission mechanism was designed according to the tooth profile.The kinematics analysis and the finite element analysis of the new bionic gear transmission mechanism were carried out using the finite element analysis software,and the comparative analysis was conducted with the standard involute gear simulation results.The results show that the contact strength of the new bionic tooth profile is better than that of the involute tooth profile under the same load.The error analysis shows that the transmission error of the bionic tooth profile is not greater than that of the involute tooth profile.
