摘要： 本文利用Laplace变换获得了挠性轴在螺旋弯曲状态下的变形与应力计算公式.根据实例计算发现现有挠性轴寿命极短的主要原因在于轴的强度不够.这一观点,有可能使螺杆钻具与螺杆泵的寿命短的现状有所改善.
Abstract: The formula for culcalation of stress and deformation of flexible axle under spiral bending is derived applying the Laplace transform.From actual calculation,it has been found that the main cause of the short life of flexible axle is its inadequate strength.Based on this,we may make improvement to prolong the life of screw drill tool and screw pump.
