“…The creation of this model is based on substituting the normal force from the twin roller in a Pacejka tire model. However, the rolling resistance increases in the case of double contact between the two rollers and traction tire compared to the flat contact patch on the road or to a single-roller dynamometer [18,19]. The authors of [18] validated their model with two coast-down tests, starting at 60 km/h and 100 km/h.…”

The authors of [18] validated their model with two coast-down tests, starting at 60 km/h and 100 km/h. Since there are insufficient thorough tire-roller analytical studies for dynamic driving maneuvers, this work investigates the adaptation of different tire models to predict the traction force behavior of the tire on the roller of the chassis dynamometer test bench.…”

The energy consumption of the electric test vehicle on the roller dynamometer test bench is thoroughly investigated in this work. Initially, we extensively examined the relevant testing approaches on chassis dynamometer test benches. Then, we presented the main issues and limitations of this type of testing facility. After that, an experimental analysis was performed by recording the NEDC and the WLTP-class 2 standard driving cycle test data. It was found that the power consumption associated with specific test maneuvers could be accurately simulated via the roller dynamometer system. However, the experimental test results showed some disparities compared to the expected results from the simulation models. These findings supported identifying the dynamic behavior resulting from the tire and roller contact. The LuGre friction model provided the solution, incorporating friction-related physical models such as stick-slip and the Stribeck effect. In addition, adjustments were made to the LuGre model to consider the dynamic influences of the roller on the tire. Finally, we created a systematic estimation model for energy consumption by integrating the boundary conditions of the test bench, a generic model for energy estimation of electric vehicles, and the proposed tire–roller contact model. The overall model requires only the measured traction speed of the test vehicle and the auxiliary energy losses as physical inputs. The results proved that the proposed model enabled the estimation of the total power consumption with high accuracy.

Fatigue damage is the most dangerous failure behavior for gearbox suspenders in urban railway vehicles, and passenger capacity is crucial to the dynamic load characteristics of the traction transmission system. Therefore, in this paper, a dynamic model of the motor car is established, and a numerical simulation is carried out under different speeds and curve radii to investigate the effect of passenger capacity on fatigue life. The research results show that passenger capacity is an essential factor affecting the fatigue life of suspenders. As the vehicle runs at an average speed, the fatigue life of the suspender is 1.07 × 106 km when the passenger capacity is 120 people; when there are 240 people, the fatigue life reduction is 60%, while it is 86% at 339 people and 92% at 389 people. The per capita fatigue damage under a straight line is 7.27 × 10−10 at 20 km/h but 1.23 × 10−8 at 60 km/h. The per capita fatigue damage under a curved line is 7.18 × 10−9 in the 600 m curve but 9.00 × 10−9 in the 400 m curve. It can be concluded that the effect of speed is more significant than the curve radius. This research achievement can provide theoretical support for vehicle design and maintenance decisions.

“…Por outro lado, outra estratégia para economizar recursos e antecipar resultados é a utilização de simulações computacionais para análise de veículos, largamente aplicada na atualidade [12] e que quando aplicada aos testes em dinamômetros veiculares, mesmo não substituindo os testes reais em dinamômetros, é uma ferramenta que acelera o processo de análise [13].…”

ResumoO uso de ferramentas de simulação bem como a realização de experimentos em escala reduzida são abordagens promissoras de análise de sistemas, capazes de reduzir tempo e recursos necessários em experimentos. Assim, este artigo apresenta uma simulação dinâmica da interação entre um protótipo de veículo elétrico e uma bancada dinamométrica de chassi, ambos em escala reduzida. Para isso, foi desenvolvida uma modelagem de ¼ do sistema (1 pneu e 2 rolos) no software ADAMS® em paralelo ao controle desenvolvido em MATLAB®/Simulink®, considerando os conceitos de dinâmica veicular longitudinal como o modelo de escorregamento do pneu, resistência ao rolamento, torques de inércia e de motorização elétrica. Foram realizadas simulações com rampa de aceleração e análise do comportamento dos componentes envolvidos, variando as pressões do pneu. Com os resultados foi possível observar as variações de velocidades e de torque nos componentes devidas ao escorregamento e a rigidez do pneu, bem como o efeito das variações da pressão de inflação no pneu nesses resultados.
