Mechanical behavior study on positive - displacement motor ' s flexible shaft 螺杆钻具挠性轴力学模型建立及主控因素敏感性分析
Because of the limited rigidity in every direction of the flexure joint , the gyro drift must be existed . the simulation analysis for this drift is done . 5 研究了由于挠性轴在所有方向上均存在有限刚度而引起的陀螺仪漂移,并进行了仿真分析; 5
