【Abstract】 The principle and characteristic of pseudodynamic testing was presented.That the error control is the key to the success of pseudo-dynamic test was pointed out.The calculation error and system error such as a major source of error was analyzed.The process of transfer and accumulation of testing error was simulated.The error sources and error accumulation process were analyzed,and the measures to suppress test error were discussed from aspects of numerical integration,test equipment,test control and so on.更多还原
