标准试验发动机燃烧时间的自动计算方法

The Automatic Calculation Method of the Burning Time in Standard Solid Testing Motor

为提高固体标准发动机试验数据处理的可靠性与效率,提出了一种燃烧时间的自动算法。该算法在曲率最大算法的基础上依托实际压强-时间曲线来确定标准Ф127 mm发动机燃烧时间。相比原有的双切线法,在参数设置不变的情况下,处理结果数据唯一,不受人为因素影响。在对该算法优化改进之后,与双切线法结果的平均时间差在5 ms之内,可在标准发动机实际数据处理中应用。

In order to improve the reliability and efficiency of the test data processing of standard solid testing motor,an automatic algorithm of the calculation on burning time is proposed in this paper.Based on the maximum curvature algorithm,the burning time is determined by the actual pressure-time curve of the standardФ127 mm solid testing motor.Compared with the bi-tangent method,the result data is unique and not affected by human factors under the condition of constant parameter setting.After the optimization and improvement of the algorithm,the average time difference between the two methods is within 5 ms,which can be used the actual data processing of standard solid motor.
