Limit Cycle Hunting of a Bogie with Flanged Wheels 总被引:3,自引:0,他引:3
Yi-Ren Yang 《Vehicle System Dynamics: International Journal of Vehicle Mechanics and Mobility》1995,24(3):185-196
When the equivalent linearization method is used to analyze limit cycle hunting of a bogie with more than one nonlinearity, the difficulty of incompatibility between the input amplitudes used to calculate the equivalent properties of nonlinearities and the corresponding output deflections arises. It is the aim of the present paper to develop a method based on optimization theory to solve the incompatibility. The heuristic analysis scheme of flutter system with one nonlinearity[16] is developed to analyze the stability of limit cycle hunting of a bogie. The results of numerical integration sufficiently support the analytical method developed in this paper. 相似文献

The influence of some excitations acting on the drive system (i.e. vertical and lateral track roughness, motor torque changes, random changes of the coefficient of friction and internal parametrical excitations caused by the kinematic properties of the tension couplings) on the rotary motion perturbations have been studied in the paper. On the basis of the physical model of the drive system, a mathematical model has been determined. The method of determining the output power spectral density function has been described and the results obtained have been discussed. 相似文献

Hot wire anenometry measurements have been made in the wake of a model motorcycle and rider mounted in a windtunnel. Only in tests with a topbox present is there clear evidence of eddy shedding. Calculations have been performed on the corresponding full-scale motorcycle to determine the frequencies of the weave and wobble modes. Comparison with the wake frequencies extrapolated to full size show that at speeds of 31-34 m/s they coincide with those of the wobble mode which is found to be efficiently coupled to the aerodynamic excitation. 相似文献

The present state of knowledge on the handling behaviour of truck-dolly-trailer system is based on parametric studies made through simulation or eigen value analysis. Any convincing study using the equations to the stability boundaries have not been reported so far due to algebraic complexities. This paper fills the gap. Effects of system parameters are assessed using equations to the stability boundaries obtained from Routh-Hurwitz criterion. The system equations of motion are derived from a bondgraph model of a linearised system. 相似文献
