摘要
为了研究链条抽油机链板结构可靠性,以LCJ12-5-14型号气动平衡链条抽油机链条链板为研究对象,进行了有限元分析,利用ANSYS可靠性分析功能,研究了链板尺寸变量、材料属性变量及载荷变量对其结构可靠性的影响。分析结果表明:链板承受的载荷对链板可靠性影响最大,其次为链板厚度,第三为链板孔内径,而链板所用材料泊松比和弹性模量对可靠性影响相对较小;减小链条抽油机载荷波动、增大链板厚度及链板孔内径可以提高链板的结构可靠性。
In order to study the structure reliability of the chain drive pumping unit chain plate,the chain plate of the type of LCJ12-5-14 chain drive pumping unit as an example,the analysis is carried out by ANSYS software.On the basis of the reliability analysis function of ANSYS,the chain plate structure reliability influencing factors such as the chain plate size variables,material attribute variables and load variables are researched.The analysis result shows that the maximum influencing factor is the load of chain plate,follows by the chain plate thickness,the third is the diameter of chain plate hole,and the Poisson ratio and elastic modulus have less effect for the reliability.Reducing the load fluctuation of chain drive pumping unit,increasing the thickness of chain plate and the diameter of chain plate hole,the chain plate structure reliability can be improved.
