摘要
光伏组件安装设备作为新型特种设备,为减小系统振动、保证光伏组件稳定精确安装,针对动力传动系统中行星轮系双功率输入的微调工况,采用集中质量法,考虑时变啮合刚度、齿侧间隙等非线性因素,建立平移-扭转非线性动力学模型,在此基础上研究各轮齿的制造、安装误差对轮系的振动及均载特性影响。研究表明:当存在制造安装误差时,太阳轮浮动可自动定心适应误差影响,在行星架误差下太阳轮偏离理论原点最远;行星轮误差对系统响应影响最为显著,相较于其他部件误差产生的振动位移存在量级差异;所有行星轮均产生相同误差时系统的均载特性优于仅有单一行星轮误差。
Photovoltaic module installation equipment is a new type of special equipment.In order to reduce the vibration of the system and ensure the stable and accurate installation of the photovoltaic module,aiming at the fine-tuning condition of the dual power input of the planetary gear train in the power transmission system,this paper adopts the lumped mass method,considering the time-varying meshing stiffness,tooth side clearance and other nonlinear factors,a translation-torsion nonlinear dynamic model is established.On this basis,the influence of manufacturing and installation errors of each gear tooth on the vibration and load sharing characteristics of the gear train is studied.The research shows that when there are manufacturing and installation errors,the floating sun gear can automatically center to adapt to the influence of errors,and the sun gear deviates the farthest from the theoretical origin under the planet carrier error.Planetary gear error has the most significant impact on the system response,compared with other parts of the vibration displacement generated by the error magnitude difference.When all planetary gears produce the same error,the load sharing characteristics of the system will be better than that of a single planetary gear error.
