针对连杆小头衬套孔位置综合误差,提出一种基于镗削衬套孔的纠正方法。为论证纠正方法的可行性,在ANSYS中建立4种分析模型,对衬套过盈联接进行有限元计算。通过与试验结果的比较,验证了有限元计算结果的准确性。研究结果和实际应用表明,纠正方法可行、有效。
Aiming at the error of the position of the small head bushing of the connecting rod, a correction method based on boring bushing hole is proposed. In order to demonstrate the feasibility of correcting the method, four kinds of analysis models were established in ANSYS, and the finite element method was used to calculate the interference connection of bushing. By comparing with the experimental results, the accuracy of the finite element calculation results is verified. The research results and practical applications show that the correction method is feasible and effective.
