“…In the traditional study of railway vehicles, if a single peak frequency of simulation acceleration is consistent with the experiment data, the simulation is successful [14][15][16]. By scaling the amplitude and wavelength of road irregularities and modifying some vehicle parameters, the author [17,18] has made a single peak frequency of the car body simulation acceleration close to the measured value. However, there is a significant error between the scaled road spectrum and the theoretical value.…”

This paper put forward an indirect method to measure the road irregularities of the monorail. Parallel computation, fused with the genetic algorithm, is used to calculate road irregularities and detect wheel failure. By intelligently modifying the vehicle parameters, the multi-rigid body model's simulation result could be close to the test data. This method overcomes the problem that the transfer function cannot be applied to the nonlinear system and the shortcoming of significant errors in the simplification process of the mathematical derivation method. Besides, it improves the traditional algorithm to shorten the calculation time and benefit big data processing. The application of the artificial intelligence method, which includes the intelligent detection of the wheel eccentricity, the brilliant weighing of human subjective judgment, the intelligent matching of the peak frequency signals of the simulation and test data, and so on, could be the highlights of this paper. The result shows the road irregularities calculated in this paper are in good agreement with that theoretical value.

“…The algorithm of the sequential emergency braking and the simulation control subsystem were implemented in this module, by defining such parameters as the maximum speed of the set, force vectors, and moments defined in the model, and by setting the parameters of the emergency braking algorithm. Defining the input and output signals of each of these modules enabled their connection and use of the co-simulation to simulate the emergency braking of a suspended monorail from the given speed, with different settings of the braking algorithm parameters [13,27,[30][31][32][33]. The structure of the computational model and the signal flow, are presented in Figure 2.…”

Testing the Impact of Braking Algorithm Parameters on Acceleration and Braking Distance for a Suspended Monorail with Regard to Acceptable Travel Speed in Hard Coal Mines

Increasing the maximum speed limit of suspended monorails, which became a very popular means of auxiliary transport, is one of the aspects of improving the efficiency of work in underground coal mines. It is especially important to enable higher (than allowed by the law) travel speed, when moving the crew to and from the workplace, which is often very distant from the shaft, and can take more than one hour of travel. Increasing this speed will make it possible to extend the effective working time of miners, which should have a positive impact on the economics of the mine. However, driving at a higher speed is also associated with increased risk of a negative impact of dynamic overload to people, e.g., during emergency braking of the suspended monorail. The concept of sequential emergency braking was developed in order to avoid excessive deceleration affecting passengers and the operator of the monorail, as well as to minimize the dynamic loads acting on the rail suspensions and on the roadway support frames, which could cause serious accidents. The developed assumptions with regard to the new method of braking are innovative in the area related to hard coal mining, where there are currently no such solutions. According to the principles of the developed concept, the total braking force was divided into two stages. The activation of the second stage depends on the deceleration measured after the time delay from activation of the first stage of braking. We present the results of the numerical simulations, which aimed to analyze the impact of changing the parameters of the braking algorithm on the braking deceleration, the braking time, and the braking distance. The possibility of changing the braking force and downward emergency braking on a high inclination angle were also taken into account during the numerical simulations. Use of the developed emergency braking algorithm enables the optimization of this process at a higher speed than is currently used. This aspect is also very important in increasing the safety for people travelling at a higher speed limit. The numerical simulations provide knowledge for safety in terms of the dynamic overload during emergency braking, without injury risk to miners or damage to equipment.

As for the batch process, it is needed to carry out a unique simulation for each group of parameters. The simplest method to achieve this goal is to uses the Simulink as the integration space. It cannot solve some complicated dynamic model set up in dynamic software. This paper introduces an intelligent batch program to enable the model solved in the dynamic software during the simulation. This paper also put forward the road equation for the suspended monorail, which has not been introduced before. The results of multi rigid body dynamics and vehicle bridge coupling dynamics are compared in this paper. It proves that the bridge vibration has little effect on the vehicle system. Through the batch process method, the effect of different parameters on the vehicle system could be obtained.
