【Abstract】 Mechanical analysis and computation have been developed on the parallel springs to improve guiding precision. Employing the mechanics of material theory, strict mechanical analyses are subject separately to parallel springs in ideal condition and in nonideal condition, a mechanical model is formed, and the computational methods of guiding errors are obtained. The effect of various parameters on guiding precision of parallel springs is demarcated accurately. By analysis of the computational methods of guiding errors, factors such as advance pull, the arm of advance pull, metrical force, the arm of metrical force, distance between the two springs, length and effective length of springs can affect guiding precision of the parallel springs. Guiding errors are decreased availably by adjusting the factors rationally.更多还原
