摘要

针对某柴油EFEADS多楔带有效长度偏差动态性能的影响，建立了多楔带-自动张紧器系统平衡方程及带轮-多楔带耦合振动模型，得出了横振方程；对标测试、修正了仿真模型，以此分析了不同极限偏差对EFEADS动态性能的影响。结果表明，极限偏差增加，张紧臂摆幅最大值减小；但在中高转速下，较大的极限偏差会引起系统不稳定，张紧臂摆幅增大，且带段横振整体增加；但不同转速的张力变化会导致带段共振频率变化，引起横振峰值对应转速漂移，而较小的极限偏差所引起的张力较大、带段横振较小。

Abstract

The transverse vibration equation is obtained by establishing the balance equation of poly-V belt and tensioner and coupling vibration model of pulley and poly-V belt. The influence of different extreme deviations on the dynamic performance of EFEADS is analyzed by calibrating and modifying the simulation model. Result shows that the maximum swing of tensioning arm reduced under the increasing of extreme deviation. At medium and high speed，the larger extreme deviation caused EFEADS instability and the swing of tensioning arm increasing. In addition，it caused the entire increasing of transverse vibration. But，the changing tension force lead to variation of resonance frequency and caused corresponding rotary speed by transverse vibration peak drifted at different speed. The smaller the extreme deviation caused the greater the belt tension and the lesser transverse vibration.
