This paper proposes a design of aerostatic guideway with the porous restriction for the vertical guideway of form measuring instrument, and analyses the design principle of the guideway.The static and dynamic characteristics of the guideway of different structures were analyzed with the software based on the finite element method, and then the optimum design was obtained by comparing the deformation and natural frequency. Finally the design of the guideway was verified by theoretical calculation and practical test that the accuracy of its various performances fully met the design requirements. The guideway can be widely applied to the form measuring instrument and other precision measuring instruments.

Simulation Results

The mechanical model of a new spring locking mechanism was established. The optimum spring parameters of the locking mechanism which meet the design requirements were provided by optimization. Using the finite element method, numerical simulation of working process of the locking mechanism was carried out. The rationality of optimization result was verified by simulation results of numerical simulation.
