【摘要】 本文深入研究了摆杆的初位角ψ０对最大压力角αｍａｘ的影响。在全面考虑压力角α的极大值和最大值关系的基础上，找到压力角αｍａｘ随初位角ψ０和中心距ａ变动的曲线，从而找到了一种按最大压力角最小来确定摆杆的初位角，并进一步确定其它基本尺寸的方法。更多还原

【Abstract】 This paper studied deeply into the influence of maximum pressure angle α max affected by initial angly ψ 0 of oscillating rod. On the basis of considering all round the relationship between extreme value and maximum value of pressure angle α, a curve,which shows that the pressure angle α max , varices with the initial angle ψ 0 and centre distance a, has been found, thus a kind of method for determining the initial angle of oscillating rod according to the least maximum pressure angle and a further determination of other basic dimensions has also been found.更多还原
