臂架驱动双纽线型起重机变幅特性分析的解析方法

Analytical Method of Luffing Character of Lemniscate Type Crane with Boom-Driving

国外某公司研制的双纽线型起重机的变幅机构设计巧妙,并已经申请了专利,以其臂架活动范围大、外观和几何形态、整机重心高度低最具特色。本文运用机构学和逆向工程原理来分析该双纽线型变幅机构的变幅特性,经一实例研究验证,表明该双纽线型起重机变幅机构具有优良的变幅运动特性和变幅工作性能。

The luffing mechanism of a foreign company’s crane is designed elaborately and patent is accredit-ed. There are great differences in outward appearance, geometric shape, luffing performance of lemniscate type crane. Based on theory of mechanism and inverse engineering, luffing mechanism characters of lemniscate type crane are studied, luffing moment is analyzed. By sample analysis, the luffing mechanism of lemniscate type crane has good kinematic characteristic and luffing operation.
