| Abstract: | In this paper,on the basis of the summary of the former work and derivation of Newton and Kirchhoff equation,the two,six,nine,eleven and twelve freedom degree of the parachute and payload system dynamics equation was deduced.Using of each mode the simulation was carried out for the same object of parachute and payload system,through compared the characteristic and difference of result of each different freedom parachute and payload system model,the applicable scope and initialized condition for each model w... |
