基于ANSYS-WORKBENCH的绞车卷筒受力分析与试验研究

ANSYS-WORKBENCH Based Load Analysis and Experimental Study of Winch Drum

根据液压张力/锚泊绞车的实际使用工况,采用ANSYS-WORKBENCH对液压张力/锚泊绞车的卷筒建立有限元模型,并对制动力和支持负载2种使用工况下的应力应变进行分析。分析结果表明:卷筒最大综合应力均小于材料的许用应力,满足强度要求。同时,采用油缸加载的方式对液压张力/锚泊绞车的制动力和支持负载进行试验,验证绞车卷筒的强度和刚度是否满足使用要求。试验结果表明:卷筒无明显变形,试验完成后绞车运行无卡滞,绞车卷筒的强度和刚度满足使用要求。

According to the actual working conditions of hydraulic tension/anchorage winch,the finite element model ofthe hydraulic tension/anchorage winch drum is established with ANSYS-WORKBENCH,and the stress-strain isanalyzed for two loading conditions,i.e.braking force condition and sustaining load condition.The maximum overallstresses obtained are smaller than the allowed stress of the material,which meets the strength requirement.Meanwhile,the braking force and the sustaining load of the hydraulic tension/anchorage winch are tested with the hydro-cylinderloading method to see if the winch strength and stiffness comply with the requirement.The experiment result shows thatthe winch drum hasn’t obvious deformation,and there isn’t clamping stagnation in the experiment,so both the strengthand stiffness of the winch drum meet the application requirement.
