Abstract：Guideway protective cover of machine tool is an important part which is used to protect the machine guide rail from external corrosion and damage. The general guideway protective cover of machine tool has simple structure and its cost is low. However, in the case of high speed movement of the machine tool, the block of one layer and the baffle of the next layer will produce severe impact, resulting in structural damage. For the purpose of its high-speed motion at the speed of 90–120m/min, two improvement schemes are proposed: adding metal rubber to the floor edge and using shear structure (improved hinge structure). Modeling was done in Solidworks and simulation was done in ANSYS Workbench. In conclusion, it was proven that adding metal rubber in the appropriate position of the baffle was feasible
