| 摘 要： | 目的研究带有端部质量的Beck杆的稳定性。方法利用Bernoulli-Euler梁理论。结果建立了计算模型,导出了运动微分方程,利用微分求积法进行了数值计算。结论考虑重力作用时的计算结果表明:末端质量会使Beck杆稳定性大幅度降低。

| Abstract: | Aim The stability of Beck's column with concentrated mass was illustrated.Methods The research is carried out on the basis of the Bernoulli-Euler Beam theory.Results The mathematical model and the differential equation of motion were established;Numerical calculation was made with differential quadrature method(DQ method).Conclusion Considering gravity action,the numerical calculation shows that the concentrated mass can greatly reduce the stability of Beck's column. |
