新型液粘绞车软启动过程动力学分析

摘要

将行星差动轮系与液粘制动器相结合设计了1种新型的液粘绞车,对液粘绞车软启动过程进行分析,建立了软启动过程的动力学模型.已知绞车卷筒输出转速时,通过求解动力学模型得到液粘制动器的输出力矩曲线.当绞车启动曲线为Harrision曲线时,液粘制动器的输出力矩按照特定曲线先增大后减小.%The paper describes a new hydro-viscous winch which incorporates differential planet gear train and hydroviscous brake. It analyzes the soft starting process of the hydro-viscous winch and establishes a dynamic model. When output speed of winch pulley is known, the output torque curve of hydro-viscous brake can be obtained from solving the dynamic model. When the start-up curve is Harrision curve, the output torque increases and then reduces.
