The train's release performance has been predicted by the present mathematical model of train's air brake system,which has been estalished basing on gas dynamics .The prediction shows that the release performance is related to the train's length and brake reduction as follows:Themore the brake reduction is,the faster the release wave propagates;the longer the train is,the slower the wave propagates; and the release wave propagates to the end of the train with varying speed.

用气体动力学原理建立模型,预测了列车不同编组长度、不同减压量后的缓解性能。预测结果表明:列车的经解性能与列车的编组长度及减压量有关,列车越长缓解波速越慢;减压量越大,缓解波速越快;缓解波按非等速由前向后传播。

In view of the effect of released wave resulting from axial extension of explosive substance, this paper, by the use of the one dimensional incompressive fluid kinetic model, solves the inward extruding motion of a finite long steel pipe under explosive pressure enhanced with an outer pipe. The fact that the result from calculation conforms with the result of experiment shows that the use of this model is adequate in the analysis of the motion of the steel pipe at least from the beginning to the middle...

In view of the effect of released wave resulting from axial extension of explosive substance, this paper, by the use of the one dimensional incompressive fluid kinetic model, solves the inward extruding motion of a finite long steel pipe under explosive pressure enhanced with an outer pipe. The fact that the result from calculation conforms with the result of experiment shows that the use of this model is adequate in the analysis of the motion of the steel pipe at least from the beginning to the middle stage.

>=The quasi-elastic release behavior and the possible intrinsic mechanisms for metal materials released from strong shock-compressions were described briefly. Based on the experimental observations and the analyses of this study, we delineated in this paper how to use the effective shear modulus to express the main features of the quasi-elastic release behavior and to determine the shear modulus experimentally. Effective shear moduli were calculated based on the measured sound velocities of LY12 aluminum under shock loadings from 20-70GPa. Comparisons with the Steinberg-Cochran-Guinan constitutive model show that this widely used constitutive model could not describe correctly the quasi-elastic release behavior for LY12 aluminum subjected to strong shock-loadings. Calculations by using our effective moduli to reproduce the release wave profiles have excellent agreements with the experiment record, implying that new constitutive equation should be developed for depicting the quasi-elastic release process.

本文由实验结果出发,简要阐述了金属从冲击压缩状态卸载时的准弹性卸载特性及其可能的物理机制。在此基础上给出了强冲击载荷作用下准弹性卸载特性的表达方式--有效剪切模量及其实验测量方法。根据本文测量的 LY12铝在20-70GPa冲击压缩下的高压声速数据,计算了它的有效剪切模量,并与冲击动力学中广泛使用的SCG本构模型的计算结果进行比较。结果表明:SCG本构模型不能用于描写准弹性卸载行为:而用有效剪切模量计算的卸载波剖面能够很好地再现实验测量结果。说明需要用新的本构方程对准弹性卸载过程进行描述。
