Abstract


In this paper, high-g shock acceleration test problems, mainly for the following two aspects: one, the onboard electronic equipment (to test the circuit module, for example) buffer principles and techniques. Second, the battery against overload characteristics of high. Purpose of this paper is to study high-speed projectile penetrating hard targets, onboard acceleration test device memory overload conditions in a high failure mechanism, strongly nonlinear circuit module shock absorbing mechanism, high overload resistant design method, the buffer material damping characteristics, battery in the high-g shock output characteristics and failure mechanism and improve the testing device in extremely harsh environments and data capture rate of survival. In extensive search of relevant literature, based on the theoretical analysis of laboratory and field tests a combination of methods, the above problems were studied: (1) systematically discussed air cannon experimental device working principle and characteristics as well as the corresponding Experimental Method. The use of air guns and felt the acceleration test device was measured coefficient of restitution of steel to discuss the physical meaning of the coefficient of restitution, and use elementary collision theory analysis of the air cannon collision process of conservation of momentum and energy distribution. (2) for storing test instruments onboard high acceleration g-value work environment, onboard test of the circuit module design high impact resistance, including non-linear theory of the buffer, the buffer material of choice, the design of the buffer member, of different densities, different pore foam, different densities, different thickness of quartz sand and rubber, nylon, polyurethane-based material such as a polymer foam cushioning energy absorption, the use of the circuit module are cushioning. (3) the use of the battery Hopkinson bar above the 100000g acceleration shock screening, the battery resistance to high g-value impact properties were studied. Discusses the impact of the battery under high overload failure mechanism and made of high impact storage test battery protective measures. Conclusions of this study using the onboard high-g acceleration test instruments were stored in high impact resistant design, and conducted a number of field trials of verification. The results show that the test instrument onboard acceleration stored in the high g-value harsh environment survivability greatly enhanced to improve high-speed projectile penetrating hard targets during acceleration signal capture rate.
