Test Simulation An Effective Approach to Reduce Development Cost of Mobile Phone

Above 70 percent of production cost is determined by development and test phase. Modern simulation method can be used to simulate test process and substitute prototype manufacturing and test phase when finishing design proposal. Test simulation can effectively find design flaws and provide engineer direct reference to modify original design or remodel. Based on practical example of mobile phone, preparation process of simulation model was related, and a new model discretization method - partition method was given. A simulating calculation for free drop test was done, detailed results analysis was given. By calculating and analyzing, design flaws could be found and corresponding modifying measurement adopted can be given. Simulation results well accord with that of practical test with physical product. Test simulation can reduce development cost greatly and shorten marketed time.
