ABSTRACT:Objective To study simulation test principle of a type of aircrafts with variable accelerations. Methods In this paper, a mathematical model of simulation system with three-axial variable accelerations was presented. The equations between objective acceleration on a point of test product and input angular velocity, angular acceleration of centrifugal and rotation angle of momentum frames were derived. Based on the known objective acceleration on a point of test product, input angular velocity, angular acceleration of centrifugal and rotation angle of momentum frame were obtained via inversing equations. Results Solutions and simulation were completed by MATLAB,the results were consistent with objective acceleration. Conclusion The result indicated that inversing equation was feasible.
