abstract

This paper presents a realistic and fast method of simulating ballscrew drives, taking into account the position-dependent changes in dynamics as the nut moves along the ballscrew. It achieves this by first using a strategy whereby the motion of the nut along the ballscrew is accurately and smoothly captured in simulations using the shape function of the finite element model as an interpolating function. Secondly, it applies a method based on Component Mode Synthesis with Modal Acceleration Recovery to achieve a full reduction of the ballscrew while still allowing the nut to move from node to node on the ballscrew. As a result the computational efficiency of the model is improved significantly without any considerable sacrifice of its accuracy.
