The traditional Paris formula ignores the influence of various uncertain factors in the crack growth process,which leads to a big difference between the predicted crack growth process and the real crack growth process. In order to improve the prediction accuracy of fatigue crack growth, a fatigue crack growth prediction method based on the improved particle swarm optimization particle filtering (IPSO-PF) algorithm was proposed. Firstly, based on the framework of the particle filtering (PF) algorithm, the particle swarm optimization (PSO) algorithm was used to optimize some particles based on the updated observation information,keeping the state of particles with large weights unchanged, and particles with small weights tend to high likelihood region, and IPSO-PF algorithm was designed. Then,combining IPSO-PF algorithm with Paris formula, a fatigue crack growth prediction model based on Paris formula and IPSO-PF algorithm was constructed. Finally, the validity of the model was verified by using the open 2024-T351 aluminum alloy data set. The results show that compared with the traditional PF algorithm, IPSO-PF algorithm can improve the diversity of particles. The prediction error of the crack growth prediction model based on IPSO-PF algorithm is 2.6%, which is better than 9.2% based on PF algorithm.

传统Paris公式预测裂纹扩展时忽略了裂纹扩展过程中各种不确定因素的影响,导致预测的裂纹扩展过程与真实的裂纹扩展过程相差较大。为提高疲劳裂纹扩展预测的精度,提出了一种基于改进粒子群优化粒子滤波(Improved Particle Swarm Optimization-Particle Filtering, IPSO-PF)算法的疲劳裂纹扩展预测方法。首先,在粒子滤波(Particle Filtering, PF)算法的框架上,利用粒子群优化(Particle Swarm Optimization, PSO)算法对基于观测信息更新后的部分粒子进行优化,保持大权值的粒子状态不变,将小权值的粒子趋向于高似然区域,设计了IPSO-PF算法;然后,将IPSO-PF算法与Paris公式结合,构建了基于Paris公式和IPSO-PF算法的疲劳裂纹扩展预测模型;最后,使用公开的2024-T351铝合金数据集对该模型的有效性进行了验证。结果表明,与传统PF算法相比,IPSO-PF算法能够提高粒子的多样性,使用IPSO-PF算法构建的裂纹扩展预测模型的预测误差为2.6%,优于基于PF算法的9.2%。

传统Paris公式预测裂纹扩展时忽略了裂纹扩展过程中各种不确定因素的影响,导致预测的裂纹扩展过程与真实的裂纹扩展过程相差较大。为提高疲劳裂纹扩展预测的精度,提出了一种基于改进粒子群优化粒子滤波(Improved Particle Swarm Optimization-Particle Filtering, IPSO-PF)算法的疲劳裂纹扩展预测方法。首先,在粒子滤波(Particle Filtering, PF)算法的框架上,利用粒子群优化(Particle Swarm Optimization, PSO)算法对基于观测信息更新后的部分粒子进行优化,保持大权值的粒子状态不变,将小权值的粒子趋向于高似然区域,设计了IPSO-PF算法;然后,将IPSO-PF算法与Paris公式结合,构建了基于Paris公式和IPSO-PF算法的疲劳裂纹扩展预测模型;最后,使用公开的2024-T351铝合金数据集对该模型的有效性进行了验证。结果表明,与传统PF算法相比,IPSO-PF算法能够提高粒子的多样性,使用IPSO-PF算法构建的裂纹扩展预测模型的预测误差为2.6%,优于基于PF算法的9.2%。

The traditional Paris formula ignores the influence of various uncertain factors in the crack growth process,which leads to a big difference between the predicted crack growth process and the real crack growth process. In order to improve the prediction accuracy of fatigue crack growth, a fatigue crack growth prediction method based on the improved particle swarm optimization particle filtering (IPSO-PF) algorithm was proposed. Firstly, based on the framework of the particle filtering (PF) algorithm, the particle swarm optimization (PSO) algorithm was used to optimize some particles based on the updated observation information,keeping the state of particles with large weights unchanged, and particles with small weights tend to high likelihood region, and IPSO-PF algorithm was designed. Then,combining IPSO-PF algorithm with Paris formula, a fatigue crack growth prediction model based on Paris formula and IPSO-PF algorithm was constructed. Finally, the validity of the model was verified by using the open 2024-T351 aluminum alloy data set. The results show that compared with the traditional PF algorithm, IPSO-PF algorithm can improve the diversity of particles. The prediction error of the crack growth prediction model based on IPSO-PF algorithm is 2.6%, which is better than 9.2% based on PF algorithm.

疲劳裂纹作为机械结构的常见损伤类型,广泛存在于各种工程结构中。据统计,疲劳失效占机械结构失效总数的50%~90%,严重影响机械结构的安全[1]。准确预测疲劳裂纹的扩展过程对缩短机器的停机时间和保障生产人员安全具有重要的应用价值。
在工程中,一般使用Paris公式实现对裂纹的扩展及疲劳寿命的预测[2]。但传统Paris公式预测裂纹扩展时一般把裂纹扩展模型的参数看作一个确定的值,通过一定数量的试验事先确定模型的参数,进而预测裂纹的扩展,这种方法预测的疲劳裂纹扩展过程也是一个确定的过程。然而,疲劳裂纹扩展是一个具有随机性的过程,受到各种不确定性因素的影响,如结构尺寸、材料缺陷、载荷和环境因素等。使用确定性的物理或数据驱动模型等传统方法进行疲劳裂纹扩展预测容易产生较大的误差[3]
粒子滤波(Particle Filtering, PF)算法被视为解决不确定性下疲劳裂纹扩展预测问题的最新技术[4]。祝志远等[5]将Paris公式和PF算法结合,实现了对30Cr2Ni4MoV钢和2024-T42铝合金两种材料疲劳裂纹扩展的预测,该方法相较于直接使用Paris公式可以大幅提高裂纹扩展预测的准确性和可靠性。LIU等[6]将PF算法应用于齿轮,跟踪齿轮的退化,并准确地预测了齿轮的剩余疲劳寿命。
虽然将Paris公式与PF算法结合的方法比直接用Paris公式进行预测裂纹扩展的预测精度有一定程度的提高,但是传统PF算法存在粒子贫化问题,限制了预测精度的进一步提高。鉴于此,关雪雪[7]提出了一种混合PF的优化算法,在重要性采样时,采用证据理论确定模型参数的先验分布,并在重采样后引入了差分进化自适应Metropolis算法移动步,改善了粒子多样性匮乏的问题,该算法在预测电池容量退化和疲劳裂纹扩展方面相比传统PF算法取得了更好的预测效果。顾震华[8]提出了一种非线性PF算法,将其与Paris公式结合实现了裂纹扩展预测,使用Q235钢试样的裂纹扩展试验数据证明了基于非线性PF算法的裂纹扩展预测精度高于扩展卡尔曼滤波和PF算法的预测精度。杨伟博等[9]提出了一种基于Paris公式和辅助PF算法的裂纹扩展预测方法,该方法将重采样后的粒子趋向高似然区,缓解粒子多样性匮乏问题,通过孔边裂纹的扩展预测试验证明该方法适用于裂纹扩展预测。WANG等[10]在PF算法的重采样过程中增加一个随机因子,提高了粒子的多样性,通过齿轮齿根处的裂纹扩展数值试验验证了所提方法的有效性。陈健等[11]同时改进裂纹扩展模型和PF算法,从这两方面优化,解决了Paris公式只能描述裂纹扩展阶段扩展规律的问题。
虽然上述学者提出了一些改进的PF算法,并将其应用于疲劳裂纹扩展预测领域,但相关文献较少,研究仍存在一定的不足。例如,国内外鲜有学者将遗传算法、粒子群算法等智能算法与PF算法结合用于疲劳裂纹扩展预测研究。因此,本文使用粒子群优化(Particle Swarm Optimization, PSO)算法优化PF算法中小权值粒子的分布,得到了改进粒子群优化粒子滤波(Improved Particle Swarm Optimization-Particle Filtering, IPSO-PF)算法;在此基础上将IPSO-PF算法与Paris公式结合,构建了裂纹扩展预测模型;最后通过试验验证了所提模型的有效性,为结构的疲劳裂纹扩展预测提供了一种有效途径。
PF算法源于贝叶斯思想和蒙特卡洛模拟理论,它可以有效地处理任意复杂的非线性模型。假设非线性动态模型由一组随时间变化无法观察的状态序列xt和一组观测序列zt组成,即
式中,xt为状态方程;zt为观测方程;vt为过程噪声;st为观测噪声;ft(∙)为状态转移函数;ht(∙)为观测函数;t为时间,取值为1,2,…。
贝叶斯估计的实质就是通过一组可以直接观测到的信息Zt={z1z2,…,zt}递推出在该时刻无法直接观测的状态变量xt,即估计pxt|z1:t)。它包括预测步、更新步两个步骤:
式中,pxt|xt-1)为转移概率密度函数,表示在给定t-1时刻的状态下,获得的t时刻状态发生的概率密度函数,反映了递推过程中状态变量的演变过程。
对于常见的非线性模型,一般使用近似的手段来简化运算假设系统,为粒子集,为粒子集中各粒子的权值,则可用来近似后验概率分布p(Xt|Zt ),即
式中,δ(·)为狄拉克函数。
重要性权值计算式为
式中,q(·)为重要性密度函数
为提高算法的计算效率,需对粒子进行重采样,实现大权值粒子替代小权值粒子,从而缓解粒子退化,提高算法的精度和可靠性。
PSO算法是一种基于群体协作的随机搜索算法,它的思想源于鸟群飞行过程中的协作行为[12]。在PSO算法中,每个粒子都有速度和位置两个属性,同时通过一定的规则定义这些粒子位置的适应度值。PSO算法的数学描述如下:
m维搜索空间内,由n个粒子组成的群体,每个粒子都由两个向量表示,分别用x=(xi,1xi,2,…,xi,m)和v=(vi,1vi,2,…,vi,m)表示粒子的位置和速度,粒子的更新过程为
式中,vijt)为粒子i的第j维速度分量;xijt)为粒子i的第j维位置分量;pijt)为粒子i的第j维个体最优解;gjt)为粒子在第j维全局最优解;ω为惯性因子;c1c2均为学习因子;r1r2均为[0,1]间的随机数。
为评价粒子的“好坏”程度,定义粒子的适应度函数[13]
式中,znew为最新时刻的实际测量值;zpred为预测的测量值;RS为观测噪声方差。
使用最新的测量值和预测的测量值定义了PSO算法的适应度函数,式(7)能够反映znewzpred之间的“近似”程度。在优化过程中,粒子可以根据个体最优解和全局最优解来优化自身的状态。使用PSO算法可将适应度小的粒子趋向于适应度大的位置,即让每个粒子都分布在高似然区域附近,使预测的测量值和实际的测量值之间的误差最小。
PF算法中的重采样步骤,在复制粒子时会使大权值粒子容易被复制保留,而小权值粒子很容易被淘汰,这样会导致粒子的多样性逐步减弱。PF算法实质上就是通过大量的随机粒子近似状态变量的真实分布,用贫化后的极少数粒子的状态来估计状态变量的真实分布,便容易产生较大的偏差。
PSO算法使得每个粒子都具备自我更新的能力,通过不断迭代更新粒子的个体最优值和全局最优值来更新自身的状态,以达到粒子都能够向最优值靠拢的目的。因此,将PSO算法引入PF算法中,让PF算法中权值更新后的粒子能够自我优化。首先,将PF算法产生的粒子与PSO算法的粒子进行关联,使之一一对应;其次,定义PSO算法中的粒子适应度函数,使PSO算法中的最优粒子对应PF算法中与实际测量值最接近的粒子;最后,让粒子通过PSO算法粒子群体间的合作,逐步向真实状态趋近。这样就可以尽可能地让粒子都位于高似然区,从而避免PF算法中大量的小权值粒子被淘汰。
在将PSO引入PF算法时,既需要使用PSO算法实现粒子的优化,又需要防止所有的粒子都趋向于局部最优的解,避免粒子的“趋同性”。因此,为了在优化PF算法中粒子状态的同时保持粒子的多样性,对粒子的权值进行大小排序,将其分为大权值粒子和小权值粒子,保持大权值粒子处于原有状态,使用PSO算法对PF算法中小权值粒子进行优化,对小权值粒子根据式(5)、式(6)进行优化,使粒子向真实状态靠近。本文所用的IPSO-PF算法与传统的粒子群优化粒子滤波(Particle Swarm Optimization-Particle Filtering, PSO-PF)算法的不同之处如下:在传统PSO-PF算法中,当确定最优的粒子后,需将所有粒子都趋向于最优粒子,这样会使部分原本就是大权值的粒子都趋向于权值最大的粒子,可能导致粒子多样性降低,同时浪费了计算资源。而IPSO-PF算法并不将所有粒子趋向于高似然区域,而是只针对小权值粒子做优化,因此既避免了粒子的“趋同性”,又提高了计算效率。IPSO-PF算法的示意图如图1所示。
IPSO-PF算法改进之处在于对重采样前的小权值粒子使用PSO算法进行优化,使部分小权值粒子趋向高似然区域,重采样后的粒子具有更好的多样性。
结构的疲劳裂纹扩展过程实质上就是裂纹长度随载荷循环次数增长的过程。在描述疲劳裂纹扩展速率的模型中,Paris公式应用最广泛,其表达式为
式中,da/dN为疲劳裂纹扩展速率;Cm均为材料参数;ΔK为应力强度因子幅值。
当两次裂纹扩展的间隔足够小时,将离散化的Paris公式作为描述裂纹扩展过程的状态方程,用于描述裂纹长度随着载荷循环次数增长的规律,即
式中,at+1t+1时刻的裂纹长度;ΔNf为预测间隔;Ctmt均为t时刻的裂纹扩展模型参数。
观测方程用于反映系统观测变量和状态变量之间的映射关系,将测量的实际裂纹长度作为观测方程,对裂纹的扩展过程进行修正。
基于IPSO-PF算法的疲劳裂纹扩展预测流程如图2所示。
具体步骤如下:
步骤1:从裂纹扩展模型待估计的模型参数中采样n个粒子,获得n个粒子的初始状态值,并假设这些粒子初始权值相等,均为1/n
步骤2:使用描述裂纹扩展过程的状态方程计算n个粒子预测裂纹长度apred,得到先验估计。
步骤3:观测是否有测量的裂纹长度ameas,若有测量值,则将n个粒子预测的裂纹长度apred与测量的裂纹长度ameas进行比较,使用式(7)对更接近实际测量信息的粒子赋予更大的权值(适应度值),若无测量值,则直接进行步骤6。
步骤4:对权值进行排序,使用改进粒子群优化算法更新小权值粒子的状态变量(待估计的模型参数),并再次计算此时各粒子的预测裂纹长度和权值。
步骤5:归一化粒子的权值,对归一化后的粒子集进行多项式重采样,得到新的状态值与权值集
步骤6:计算各裂纹长度的加权平均值,将其作为下一时刻的预测裂纹长度,若预测裂纹长度大于结构失效的临界裂纹长度ac,则结束预测,否则,返回步骤2。
为了说明IPSO-PF算法在裂纹扩展预测中的有效性及先进性,使用WU等[14-15]做的30条2024-T351铝合金裂纹扩展的公开数据集进行验证。将图3所示的30条裂纹扩展数据的平均值作为先验信息,取裂纹扩展速率最快的曲线1(试件1)和裂纹扩展速率最慢的曲线2(试件2)的部分裂纹长度作为实际观测数据,预测这两种极限情况下的裂纹长度的扩展过程。
试验数据说明,试验使用标准紧凑拉伸试样,宽度和厚度分别为50 mm和12 mm,试验开始时的初始裂纹长度为18 mm。试验使用载荷幅值为3.6 kN的恒幅正弦信号加载,应力比为0.2。
计算30条裂纹扩展曲线的平均值并求取30条裂纹平均扩展速率,用式(8)对求取的平均扩展速率进行拟合,拟合结果如图4所示。
得到2024-T351铝合金对应的参数为C=3.08×10-30m=3.24。为简化计算过程,可用lg C替代C,并假设参数[lg Cm]服从二元正态分布[16]
为实现对这两条裂纹的扩展预测,在曲线1和曲线2上分别取3个点作为实际的观测数据。曲线1(试件1)的观测数据分别为(10 000,19.254)、(20 000,21.026)和(30 000,23.259)。曲线2(试件2)的观测数据分别为(10 000,18.553)、(20 000,19.310)和(30 000,20.264)。取粒子数n=1 000,根据李光保等[17]的建议,粒子群优化算法参数c1=c2=2,ω=0.9,迭代次数为50,取IPSO-PF算法中权值较小的一半粒子使用PSO算法优化。
将Paris公式分别与PF算法和IPSO-PF算法结合,得到Paris-PF方法和Paris-IPSO-PF方法,对曲线1和曲线2的裂纹扩展过程进行预测。曲线1和曲线2的裂纹扩展预测曲线分别如图5图6所示。由图5图6可以看出,Paris-IPSO-PF方法预测效果最好,Paris-PF方法预测效果次之,Paris方法预测效果最不理想。
假设临界裂纹长度ac=30 mm,计算此时实际循环次数和各种方法预测循环次数的相对误差。表1表2所示分别为曲线1和曲线2对应的相对误差。由表1表2可知,基于Paris方法的两条曲线平均相对预测误差为27.1%;基于Paris-PF方法的两条曲线平均相对预测误差为9.2%;基于Paris-IPSO-PF方法的两条曲线平均相对预测误差为2.6%。这表明Paris-PF方法和Paris-IPSO-PF方法相比于直接使用Paris方法进行裂纹扩展预测的精度均有大幅提高,两种方法均能有效预测裂纹的扩展过程,大幅提高裂纹扩展预测的准确性。相比于Paris-PF方法,Paris-IPSO-PF方法在预测裂纹扩展方面具有更高的准确性。
曲线1和曲线2到达临界裂纹长度时,利用Paris-PF方法和Paris-IPSO-PF方法对粒子预测的循环次数分布图如图7图8所示。由图7图8可以看出,基于传统PF算法预测裂纹长度扩展到临界裂纹长度时,大量的粒子出现在偏离真实值的位置,特别是对曲线1的预测,大量粒子预测的次数集中在35 000次附近;而基于IPSO-PF算法预测粒子大多出现在距离真实值较近的位置,呈现出正态分布的特点,粒子分布更加合理。造成上述结果的主要原因是PF算法在重采样过程中有更大的概率保留并复制大权值粒子,淘汰小权值粒子,导致样本贫化。在粒子根据第一次的观测信息进行状态更新后,部分粒子陷入了局部最优的陷阱,这类粒子具有较大的权值,然后直接进行重采样时,对这类粒子状态进行了大量的复制,从而导致大量的陷入局部最优的粒子保留到最后,使真正接近模型参数真实值的粒子减少,最终导致预测结果与真实结果存在较大的偏差。而IPSO-PF算法将小权值粒子趋向于高似然区域,相当于“稀释”了陷入局部最优粒子的权值,使重采样时避免大量复制陷入局部最优的粒子,提高了粒子的多样性。因此,粒子分布更加合理,最终使Paris-IPSO-PF方法对裂纹扩展的预测结果与真实结果更加接近。
运用PF算法思想,将裂纹扩展过程中的不确定性考虑在内。分析了PF算法的不足,使用PSO算法对其进行优化,得到IPSO-PF算法,并得出以下结论:
1)该算法缓解了粒子多样性匮乏问题。
2)构建了基于IPSO-PF算法的疲劳裂纹扩展模型,并使用2024-T351铝合金公开数据集进行了仿真验证。结果表明,基于IPSO-PF算法的裂纹扩展预测方法的平均预测误差为2.6%,相比于传统基于PF方法的预测精度提升了6.6百分点。
