The Jacobian matri x of the low impact docking mechanism (LIDM) contains relationship information b etween the actuators and the load sensing ring′s forces and torques. However, f orces and torques have different dimensions. The Jacobian matrix is decomposed i nto two sub matrixes, that are related to force and torque transmission respect i vely. Based on the two sub-matrixes, the mathematical models of force and torqu e transmissibility can be developed. And some mechanical properties about force a nd torque transmission of LIDM can be analyzed by calculating the distributi on of force and torque transmissibility within work space. The analyses show tha t the distribution of force and torque transmissibility is ellipsoid after the s tructural configuration of docking mechanism is determined, showing different l aws with load sensing ring during moving along different paths. Further, the res ults of the study are important to the performance estimation and optimization about st ru ctural properties of the docking mechanism which is represented by LIDM.
