In order to study the phenomenon and law of projectile penetrating into high-strength concrete, the experiment of projectile penetrating into C60 high-strength concrete target is carried out, and the experimental results are compared with those of C35 normal strength concrete. The penetration depth and projectile erosion are analyzed by means of calculation method based on cavity expansion theory, empirical penetration formula method and nodes back-off method. The calculated and experimental results show that the overload of projectile penetrating into C60 concrete is 1.8 times of that of projectile penetrating into C35 concrete, and the penetration depth is 52%. The surface damage of C60 concrete target is greater, indicating that the brittleness of concrete gets larger with the increase of strength. The erosion of projectile penetrating into high strength concrete is more serious in the case of the same aggregate cutting conditions, indicating that the erosion effect of high-strength mortar gets larger.

On the basis of analysis of loading transfer relation, a dynamic differential equation is established based on multi-DOFs spring-mass-damper system, and the dynamic parameters, such as natural frequency and damping ratio, are determined by the harmonic response analysis. Then the dynamic characteristics under different penetration conditions are predicted by numerical integration method, and the reason why the predicted dynamic characteristics differ greatly from the calculated result of the traditional empirical formula is analyzed from the amplitude-frequency response.The credibility of the proposed model was verified through artillery test, and the overload signal in penetration process was collected. The calculated value of overload signal is in agreement well with measured result. The result shows that the proposed model is more suitable to predict the dynamic characteristics of warhead or fuze in penetration process. It is shown that penetration warhead exhibits obvious vibration amplificatory characteristics and periodic oscillation characteristics in considering the axial vibration effect, and the dynamic characteristics of warhead are the most important factor affecting the dynamic characteristics of circuit module in fuze.Key

Simulation models for oblique penetration of projectile into multi-layer steel target were established by LS-DYNA, the action process of the projectile obliquely penetrating into the multi-layer steel targets was analyzed, and the influence rules of projectile inclination angle, projectile velocity, target thickness and projectile deformation on the trajectory characteristics were obtained. The simulated results agree well with the experimental data. The results show that the trajectory deflection increases with the increase in inclination angle, and decreases with the increase in impact velocity, and its influence decreases with the increase in impact velocity. The trajectory deflection changes from overall downward to overall upward， and the influence of target thickness on the trajectory deflection increases with the increase in its thickness. The trajectory deflection of the rigid projectile is smaller than that of the deforming projectile.

The test and simulated signals are segmented by penetration layers. The layer and inter-layer coefficients of acceleration signal for each layer are calculated by subtracting every amplitude of signal points by former one and summing the absolute values of difference values. The larger the two sets of evaluation indexes are, the more severer the superposition degree is. The calculated results of test and simulated signals are used to demonstrate the efficiency of evaluation indexes. The calculated results of layer and inter-layer coefficients in 3 sets of data show that the layer and inter-layer coefficients are smaller if the disturbance superposition degree is lower, and vice versa. One set of data is extracted from the calculated results of evaluation indexes of acceleration signal for two detonation control circuits in one penetration warhead, and the calculated deviation is less 5%. The calculated result is consistent to the results of qualitative analysis and spectral analysis. The experimental results show that the layer and inter-layer coefficients are efficient for evaluating the disturbance superposition degree in multi-layer penetration acceleration signal.
