摘要
本文把装有油-气弹簧的车体作为兼有平方和立方项两自由度非线性系统。借助于摄动理论,求得了系统对于简谐激励的周期解及频响关系;发现并讨论了“软”“硬”不定、偏振、耦振及拍振等新的现象和特征。仿真实验、数值计算与摄动解的良好吻合,使所得结论得以验证。从而为油-气悬挂式车辆的工程设计与使用提供了理论分析的途径。
In this paper, the body of the vechicle with a hydro-gas spring is considered as a nonlinear system having both square and cubic term with two degrees of freedom. By means of the perturbation theory, the periodic solution and the relation between excitation and response of the system under the action of harmonic excitation are obtained. This paper discove red and discussed the new phenomena and characteristics of this system, such as indefinition of hardening or softening spring, deviation, coupling and beat. The analogue result and digital computation are compatible with the perturbation solution, thus proving our conclusions. This paper pro vides a method of theoretical analysis for the engineering design and application of vehicles using hydro-gas suspension.
