摘要
根据输油臂的结构及操作条件 ,对回转接头进行受力分析和力学模型的进一步简化 ,将原来的静不定问题转化为静定问题 ,从而大大简化了回转接头的设计计算。对回转接头的寿命检验借鉴了关节轴承的计算方法 ,使计算结果更为合理。
Structure and operation conditions of loading arm are described,force exerted on the swivel joints is analyzed and the mechanics model of the joints is further simplified.Therefore,the previous statically indeterminate problem is changed into statically determinate one,resulting in significantly simplified swivel joint design and calculation.Also,the lives of the swivel joints are verified using the calculation method for the life of knuckle bearing.
