中文摘要:为方便有轨起重机轨道修正方案的可行性验证,基于AutoLISP对修正轨道进行仿真。仿真模型使内侧车轮与内侧轨道完全重合,利用几何关系绘制外侧车轮轨迹。外侧车轮与外侧轨道的偏移量小于2倍轮轨中心距,说明小车可以顺利通过修正轨道,否则会出现卡轨。某型号起重机实际参数验证本文方法的可行性。

Dynamic simulation on no-circular rail of rail crane based on AutoLISP
Abstract:In order to verify the feasibility of the rail correction scheme for rail crane, the modified rail is simulated based on AutoLISP. The inner wheel fully coincides with the inner rail in the simulation model. The outer wheel trajectory is drawn by geometric relationship. The deviation between the outer wheel and the outer rail is less than 2 times the center distance between the wheels and tracks, and it shows that the trolley can pass the track smoothly. Otherwise, the trolley would gnaw rail. The feasibility of the method is verified by the actual parameters of some type of crane.
keywords:rail crane  gnaw rail  rail correction  simulation verification  deviation
