摘　　要：针对用传统的一次二阶矩法分析可靠性时,由于所取的极限状态方程不同,造成所求的可靠性指标有较大差别的问题,提出改进的一次二阶矩方法,即:验算点法。并以圆弧齿轮为例进行了分析,通过与MonteCarlo数值模拟结果的对比表明,改进的一次二阶矩法能有效改善计算精度。Different limit state function can be used to calculate the reliability, however with a greater distinctness between the results calculated. So the advance LOSM method is proposed, namely the designing check point. The Circular arc gear example was employed to demonstrate this modified method. Comparing with the results of Monte Carlo simulation, this modified method can effectively improve the precision of reliability calculation.
