| Abstract: | A transient Reynolds' equation is derived.The Taylor series expansions of the oil film thickness and pressure are used to calculate and normalize the nonlinear oil film force,the linear and nonlinear stiffness and damping coefficients and their coupling coefficients. Four order relative errors of the nonlinear oil film force are studied. It is showed that the relative errors of the nonlinear oil film force are becoming larger and larger with an increase of the oil film thickness. |
