| Abstract: | By Monte-Carlo method and making simulative experiment with computer, using the method of multivariate linear regression, the general regression equation of planar linkage's error transfer coefficient (ETC) for pair clearance is given. And it is set up the regression equation which displays the effect of driver's relative length to ETC, while the pair fit is invariable. The studying result shows that the regression equation's form of the effect of driver's relative length to ETC is alike while dimension type is variable. And, by curves, the effect of dimension type to ETC and mechanism's output motion standard deviation is shown. |
