Abstract:
1. A method of simulating service loads comprising the steps of: a) developing a service load history database including multiple time series models representative of different service load conditions; b) combining the multiple time series models to form a simulation test service load model for a time span of a testing object, wherein each time series model is included in the simulation test service load model in a proportion that is based on an estimated time within the time span for which the service load condition associated with the respective time series model will be applicable; c) adjusting a variance of each of the time series models of the simulation test service load model and creating an accelerated service load model; d) regenerating random vibration load data based upon the accelerated service load model; and e) feeding the random vibration load data to a drive simulation system to thereby cause the drive simulation system to simulate service loads in accordance with the random vibration load data.
