摘要: 在对原有系统结构加以改进和同步点速比变化率实施控制的基础上,建立了传动系统于混合无级变速、同步点转换和纯无级变速三种工况下的键合图仿真方程。仿真结果表明:新系统于同步点对车体的冲击度远小于标准规定的10m/s{sup}3。

Abstract: By controlling the rate of ratio changing and refining the design, a bond graph simulation model is established under the condition of hybrid CVT mode, synchronous mode and pure CVT mode, and the state space equations are derived for performance analysis, control strategy optimization, and design refinement. The simulation results indicate that the jerking motion of the improved transmission system is under the international criterion 10m/s3.
