【摘要】：为了解决有轨起重机在转弯时,出现的啃轨问题。提出先修正内侧轨道再修正外侧轨道的方法。对于内侧轨道,在直线段和圆弧段轨道加入一段缓和曲线,使曲率半径从无穷大逐渐过渡到圆弧曲率半径;对于外侧轨道,通过四角门框计算出外侧两角点的轨迹。通过求两角点轨迹的中线,即四角门框的外侧轨道,再叠加多轮修正值δ进一步修正外侧轨道。应用Adams进行动态仿真,验证修正轨道是否可以安全通过,并用Adams仿真优化起重机基距、平衡梁尺寸。结果表明,加入的回旋线长度Ls越大,有轨起重机大车在转弯时,出现的偏移量越小。同时,得出有轨起重机平衡梁和基距最优解。
[Abstract]:In order to solve the problem of gnawing the rail when the rail crane turns, the method of correcting the inner track and then the outer track is put forward. For the inner track, a relaxation curve is added to the line and arc track. The curvature radius is gradually transferred from infinity to arc curvature radius; for the outer orbit, the trajectory of the outer two corners is calculated by the quadrangular door frame, and the outer orbit of the quadrangular door frame is obtained by finding the central line of the trajectory of the two corners, that is, the outer orbit of the quadrangular door frame. The lateral track is further modified by superposition of multi-wheel correction value 未. The dynamic simulation with Adams is carried out to verify whether the modified track can pass safely. The base distance of crane is optimized by Adams simulation and the size of the balance beam is optimized. The results show that, The greater the raceway length of the rail crane is, the smaller the deviation will be. At the same time, the optimal solution of the equilibrium beam and the base distance of the rail crane can be obtained.
