Using simulation test method to evaluate the performance of fuze is very helpful to reduce the cost of fuze and also speeds up the fuze research and development. Equivalence of simulation test method and real artillery launch test is a criterion to decide whether the test results are reliable. Fuze inertia arming device is taken as an example. Firstly, an equivalence criterion was proposed according to its working principle. Secondly, a mathematical model of fuze inertia arming device was established. Thirdly, a software simulation of the dynamic response of fuze inertia arming device in a series of simulated artillery launch environments and the real artillery launch environment were accomplished. At last, the simulation data analysis proved the feasibility of equivalence.

In this paper, a compact triple-band handset antenna (THA) and its three element array are presented for dual-mode user equipment (UE) applications, with their structures designed and performance validated by measurement. Then, based on the obtained electromagnetic parameters, a 2×2 TD-LTE multi-input and multi-output (MIMO) UE system with UE local DCS1800 interference is studied by simulation in such a realistic manner. Under given interference power level, non-linear relation models of the LTE system throughput and the system isolations are achieved, which can be used to evaluate these system performances.
