Abstract�� The dynamics and extraneous torques models of an anti-load simulator were built according to the complex vector and virtual displacement principles respectively. To avoid the problem that the solution is not consistent when the traditional genetic algorithm (GA) is used in the parameters optimization, the hierarchical optimization of GA based on the parametric sensitivity was applied to optimize the design parameters of the mechanism of the anti-load simulator. Then a virtual prototype was designed according to the optimizing results, and testified by the simulation in ADAMS with various loads applied. The results show that the prototype is able to withstand the complex environment conditions and loads in simulating tests. Finally, the real anti-load simulator was established with functions working in environment tests and under various loads.
