Title The Dynamic Analysis And Optimization Of Air Hammer Test Device
Abstract
The rapid development of high-tech military equipment leads to higher requirement of the fuze. The testing of the reliability of the fuze in the environment of high overload and wide pulse and timing correctness is particularly important. However, the existing shock test methods have their own advantages and disadvantages so air hammer test equipment is designed to meet the testing needs. This paper focuses on four aspects of the equipment: operational principle, dynamic analysis, circuit design and test and operation.
Operational principle---analyzing the structure, working principle and working process of air hammer test device.
Dynamic analysis---conducting theoretical analysis and calculation of the movement in the bore by applying Calculus and software programming. This paper also employs ANSYS/LS-DYNA to carry out the simulation of finite element in order to complete the strength check.
Circuit design---designing the electronic-control-system circuit of the device thereby realizing automatic control.
Test and operation---conducting tests, summarizing test data and comparing with the outcome of simulation in order to verify the feasibility of the design.
Keywords dynamics FEM circuit
