• 410 A proposition of analysis method for the system with contact between largely deformable body and rigid body

抄録

In recent years, planetary explorations of asteroids and comets are gathering a lot of attention. In general, landing and jumping on the surface is quite difficult due to rough and unpredictable surface of planetary body. But efficient analysis method of dynamics for such operation has not been established So, it is necessary to develop an analysis method to derive the contact force between deformable planet surface covered with rocks, sand and regolith in planetary exploration. In this paper, we propose a method for analyzing the contact force between deformable ground and spacecraft. The spacecraft is assumed to be rigid body and the planet surface is formulated by Material Point Method (MPM) which is a kind of particle method. Furthermore, in order to analyze the contact behavior between them, a method for multiple simultaneously contact problem, which formulate the problem by Linear Complementarily Problem (LCP), is employed. The proposed method is validated by numerical analyses and some of the results are discussed by the use of theoretical values, and also applied to practical example which introduce the lander model.
