Abstract：Ground simulation tests of spacecraft separation require accurate force predictions as the key link in the tests. This study analyzed the cable force transfer during high-speed spacecraft separation tests. A dynamic model of the cable hoist system was developed based on Newton's laws. The second-order partial differential equation for the test function was then solved using spatial discretization. The solution predicted the force on the rope as it moved to study the factors influencing the force. The model accuracy was verified by numerical examples. The results show that the model can accurately simulate the force on the rope for high-speed spacecraft separation tests.
