切线性质
The pumping induced tangential strain mainly displays compression property, its magnitude decays rapidly along with radius from the well increasing, and increases exponentially along with pumping time increasing.
切向应变主要表现为环向挤压,且其应变大小随半径增大迅速衰减,随时间增长呈指数增大。
Although the contacting pressure of the single oil scraper ring remains unchanged, the laminated property on cylinder liner is improved and the tangential force can be reduced by 40% to 50%, and decreases the friction resistance.
新设计的单刮油边螺旋撑簧油环在接触比压保持不变的前提下,明显地改善了对气缸壁的贴合性,且油环切向弹力下降40%~50%,从而降低了摩擦阻力。
