摘　　要：多楔带传动系统带横向振动的计算和控制是研究的难点。文中分别将带简化为弦线模型和梁模型,计算了典型三带轮多楔带传动系统中带横向振动的幅值;将基于弦线模型的带横向振动求解结果与梁模型结果对比分析,探讨在带横向振动的计算中用弦线模型替代梁模型的可行性;并以稳定状态下带横向振动幅值最小和弦线模型与梁模型结果之间相对误差最小为目标,通过优化带的各设计参数,实现对带横向振动的控制。The calculation and control method of transverse deflection in serpentine belt drive system is a challenging subject.In this paper,the amplitude of transverse deflection in a prototypical serpentine belt system is calculated with the belt modeled as string and beam respectively.A comparison was made between the calculation result of string and beam,and investigated the replacing ability of string and beam.An optimization method to minimize the amplitude of transverse deflection and relative error between string and beam was presented.The result shows that span transverse deflection is under control ultimately.
