为论证某型飞机起动机轴承座修复方法的可行性和修复衬套过盈联接结构参数的合理性,对修复衬套过盈联接的可靠性进行研究.将导致修复衬套松动和轴承座胀裂的因素作为随机变量,建立修复衬套过盈联接的可靠度模型.基于ANSYS对修复衬套过盈联接进行了有限元计算,并对有限元计算结果进行了实验验证.根据修复衬套过盈联接的可靠度模型和有限元计算结果,计算得出修复衬套过盈联接的可靠度.计算结果和实际应用情况表明,修复衬套过盈联接结构参数设计合理,修复方法可行、有效,且具有高可靠性.
In order to demonstrate the feasibility of repairing the bearing block of a certain type of aircraft starter and the rationality of repairing the structural parameters of the interference fit of the bushing, the reliability of the interference fit of the repaired bushing is studied, which will lead to the looseness of the repaired bushing and the bearing expansion As a random variable, establish the reliability model of repairing the interference connection of the bushing.Finally, the finite element calculation of the interference connection of the repairing bushing is made based on ANSYS, and the experimental results of the finite element calculation are validated.According to the repairing bushing The reliability model of interconnected joints and the results of finite element analysis are used to calculate the reliability of the repaired bushing’s interference connection.The calculation results and practical applications show that the parameters of the repaired bushing’s interference joint design are reasonable and the repairing method is feasible and effective, And with high reliability.
