摘要
依据赫兹接触理论建立了角接触球轴承分析模型。通过改进的遗传算法对分析模型的非线性方程组进行求解,并通过算例验证了该方法的有效性。结果证明,采用改进的遗传算法对角接触球轴承分析模型进行数值求解,可以有效解决Newton-Raphson法求解方程需要设定初值且易出现不收敛的问题。
In this paper, an angular contact ball bearing analysis model has been established based on Hertz contact theory. Solving nonlinear equations by improved genetic algorithm and verified the effectiveness of the method through numerical experiment. The results proved that the adoption of improved genetic algorithm to solve the analysis model of angular contact ball bearing, can effectively resolve the problem of the Newton-Raphson method such as no convergence and need initial value, the calculation results is satisfying.
