摘要:
针对液流试验中出现的单向阀系统自激振荡现象，建立了描述该系统动态过程的非线性动力学模型。通过数值计算证实了系统在一定条件下出现极限环，系统是局部稳定，大范围不稳定，计算结果与试验相吻合。分析了此系统产生自激振荡的原因、影响因素及抑制措施。
Abstract:
In order to investigate the self-oscillation phenomenon of the check valve system happening in the hydraulic experiments, a nonlinear dynamics model was established to describe the dynamic process of the system. The limit cycle oscillation was emerged under specified conditions through the simulation tests. It is found by the numerical calculation that the system is local stable but unstable in large scale. The simulation results agree well with the experimental ones. The reasons why the sytem produces self-oscillation, the infuencing fctors of self-oscillation and the measures restraining the self-oscillation are analyzed.
