对比结果表明，叠合式节流阀片的设计原则、当量厚度和应力计算方法是准确和有效的。
The compared results show that the design scheme is effective and the formulas for equivalent thickness and maximum stress of the throttle multi-slice are accurate enough.
来达到廓形各点为当量磨削厚度为常值的目的，提高凸轮的磨削精度。
Therefore, it can eliminate the profile error caused by the change of equivalent grinding thickness in the common grinding method and increase the cam grinding precision.
而以板底拉应力等效为指标的基层顶面当量回弹模量值能较为真实地反映基层刚度和厚度变化对板底拉应力的影响。
But the principles of stress equivalence could accurately reflect the influence on the cement concrete pavement stress by the modulus and thickness of semi-rigid type base.
