Abstract
Considering that it is very difficult to finish low gravity in simulating landing experiments of lunar lander, the existed low gravitation experiment methods used abroad were studied and compared. On the precondition of taking experimental cost and space as major factors, it is concluded that the slide-wheel balanced method is very economic and practical. On the base of taking account of the moment of inertia of slide-wheel and frication of rotating shafts, the calculation formulas of the counter weight mass and the relative error of acceleration were derived with Largrange equations, and the formulas were verified by experiments.
