摘要： 针对在路面激励，系统阻尼以及惯性负载作用下，纯电动汽车（Electric vehicle，EV）动力传动系统呈现复杂的非线性扭转振动特性，造成EV动力传动系统失稳的问题，考虑永磁同步电机（Permanent magnet synchronous motor，PMSM）制造和安装引起的静态偏心和路面激励引起的动态偏心的影响，建立EV动力传动系统非线性扭振模型，求解并分析无扰动Hamilton系统的平衡点，采用控制变量法分别研究路面激励波动，系统阻尼渐变以及惯性负载跃变对EV动力传动系统非线性扭振特性的影响，得到EV动力传动系统失稳的具体途径和机理。研究表明：分别取路面激励f₁、系统阻尼μ₁及惯性负载m₁作为单一变量，当f₁ < 0.23，μ₁ > 0.2或0 < m₁ < 0.3时，EV动力传动系统表现为稳定的一周期运动；当0.23 < f₁ < 0.52，0 < μ₁ < 0.2或0.3 < m₁ < 0.5时，EV动力传动系统由倍周期分岔通往混沌运动；当0.52 < f₁ < 0.62或0.5 < m₁ < 0.6时，EV动力传动系统由混沌运动转变为三周期运动；随着路面激励f₁或惯性负载m₁的进一步增大，即0.62 < f₁ < 0.8或0.6 < m₁ < 0.85时，EV动力传动系统表现为倍周期运动与混沌运动交替的运动状态，而随着系统阻尼μ₁进一步增大，即μ₁ > 0.2时，系统始终表现为稳定的一周期运动。

Abstract: The effect of the road excitation, the damping and inertia resistance causes nonlinear torsional vibration and leads to instability of EV powertrain. Nonlinear torsional vibration model is established considering the effect of rotor eccentricity. The equilibrium points of non-disturbed Hamilton system are solved. The influence of road excitation, damping and inertia resistance on the nonlinear vibration of EV transmission system respectively is studied. Moreover, the approach from periodic motion to chaotic motion is analyzed as well. The results show that EV powertrain makes one period motion when f₁ < 0.23,μ₁ > 0.2 or 0 < m₁ < 0.3 respectively. When 0.23 < f₁ < 0.5, 0 < μ₁ < 0.2 or 0.3 < m₁ < 0.5, EV powertrain transforms from stable periodic motion to chaotic motion through periodic bifurcation. When 0.52 < f₁ < 0.62 or 0.5 < m₁ < 0.6, EV transmission system transforms from chaos to three periods motion. EV powertrain is characterized by the alternation between the periodic motion and the chaotic motion with the increase of f₁ and m₁. When μ₁ > 0.2, the system always makes one period motion as the parameter μ₁ increases.
