- 运用动力间隙元不仅能合理描述钻柱与井壁的接触碰撞过程，还能考虑井壁变形和泥饼的能量吸收，并用Newmark法求解钻柱动力学平衡方程。 This model is solved by dynamics gap element which can not only describe the contact and impact between drilling string and bore hole wall but also present the deformation of bore hole wall and energy absorption of mud cake. The dynamic equilibrium equation is solved by Newmark method.

- 可以利用Newmark法求出各时间离散点的动力响应，再利用直接法求解各时间离散点的伴随向量（两者的求解是分离的），从而可得到各临界时间点上的灵敏度。 The dynamic responses on critical time can be worked out using Newmark method, and the adjoint vector can be worked out using direct method (the solving of responsesand adjoint vector is separate), then we can get the sensitivity on critical time.

- 根据Davenport脉动风速谱函数与日本规范中提出的横风向脉动风力谱系数函数模拟的顺风向与横风向脉动风压时程,采用Newmark法计算了一栋高68m的高层建筑物的风振扭转动力反应时程。 A method for evaluating the wind induced torsion vibration on rectangle high rise buildings is presented with simulation of the process of wind pressure fluctuation in this paper. The fluctuating pressures both in the along wind direction and in the across wind direction are simulated according to Davenport spectrum density function and the fluctuating pressure spectrum density function specified in Japanese building code.
