“…According to previous studies [14][15][16][17][18], the vibration at frequency above 50 Hz is not significant, and the damped characteristic of pneumatic tires attenuates the accelerations at high frequencies. In this paper the Nyquist frequency in the simulation is 50 Hz.…”

The aim of the paper is to report a systematic methodology which is used to evaluate and improve the ride comfort. An accurate model is necessary for further investigation and optimization. The vehicle dynamics model of tractor with tandem suspension is modeled and simulated in dynamics software ADAMS, which is redeveloped to add a function of automatic parametric modeling and simulation. The modeling methods of nonlinear characteristic components and various road excitation inputs, which can be simply seen as the implementation means for the model solution, are introduced. A new index called annoyance rate is presented to indicate the quantitative correlation between objective method and subjective comment. The quantitative correlation between them, which is quite different from the qualitative ''comfortable'' or ''uncomfortable'' results attained by objective evaluation, can be defined by function and regarded as a basis to scientifically evaluate and improve the ride comfort. According to the request of performance-based design, the parameter sensitive analysis and structure optimization have been carried out to find the trade-off among ride comfort, maneuverability and safety. The approach has proved to be very effective for predicting and improving the ride comfort by experiment results. The methodology can be also used for any other specific category of vehicle.

“…For the model of the rail vehicle the standard methods are commonly applied, e.g. FEM used by Stribersky et al [2] or neural networks by Sayyaadi [3]. Cheli et al [4] solved the system with 68-degree-of-freedom, where FEM software was utilized.…”

New method of solution of the motion equation of the mechanical system with higher degree of freedom is applied on the investigation of the vertical vibration of the vehicle. Mechanical model is composed from three spatially elastically supported and bounded bodies. Model represents the chassis of railroad vehicle with elastic and dissipative elements. Proposed method enables to determine the vertical displacement of the arbitrary point of the system.

“…Therefore, vibration accelerations are generally effective in evaluating ride comfort of railway vehicles. Various studies have been conducted to measure vibration accelerations during the running of railway vehicles or roadway vehicles, and to present the requirements and limitations for ride comfort [1][2][3][4][5]. Many countries use various standards and criteria in evaluating ride comfort of railway vehicles.…”

The dynamic model was developed to evaluate vibration accelerations and ride comforts during the running of the Korean-standardised rubber-tired light rail vehicle. Ride comfort indexes were analysed and tested in accordance with UIC 513R by using the dynamic model and the actual vehicle in the test track. Based on the comparisons between analysis results and test results, the validity of the developed dynamic model was evaluated. It was verified whether or not the developed Korean-standardised rubber-tired light rail vehicle met the specified target specification on ride comfort. In addition, the influence of the wearing of guide wheels on ride comfort was estimated.
