【摘要】 针对皮带传动过程中平稳性较差及皮带容易磨损问题,在考虑皮带材料刚度和阻尼的条件下,利用数值分析方法,对皮带传动系统的动力学特性进行研究。分析结果表明:皮带在带轮表面上爬行时,会产生一定的角速度损失;皮带与带轮在考虑摩擦力时接触力呈现减小的趋势,随着摩擦因素的增加,接触力不断增加;不同摩擦因素下的接触力随着接触角增加呈现双峰趋势,峰值接触力在不同摩擦因素下出现位置不同。更多还原

【Abstract】 For the poor stability and easy to wear belts in the process of belt drive,in consideration of the belt material stiffness and damping conditions,by using of numerical methods,the belt drive system dynamics characteristic are studied.The analysis results show that a certain angular speed loss due to the belt creeping over the pulley surface,the contact force of belt and pulley display a decreasing trend in considering friction factors,with the increase of friction factor,the contact force increase,the contact force under different friction factor with the increase of contact angle shows a trend of twin peaks,at different friction factor,the peak contact force occurs at different location.更多还原
