“…Model 1 uses a linear elasto-plastic formulation and Model 2 uses a nonlinear formulation to emulate the multi-leaf spring. For details of the two models, the reader is referred to reference [20]. The two models are given the same displacement input as was given to the physical spring.…”

-Engineers and scientists are often faced with the problem of objectively comparing time histories of measured and/or simulated data. This paper presents a reliable and intuitive validation metric for use in the validation process. The proposed validation metric is able to quantify the agreement/disagreement between deterministic system response quantities of interest obtained from measurements on a physical system and predictions from a mathematical model. The validation metric is based on the relative error and the challenges concerning the use of the relative error on periodic signals are addressed. The validation metric is compared to similar metrics and their advantages and limitations are discussed. The results show that the proposed validation metric gives a comprehensive error that is able to quantify the agreement between two periodic signals and is easily interpretable.

“…The leaf spring equivalent processing method is very important for getting the right figure of the electrical bus frame stress in addition to the correction layout battery pack and so on, because the leaf spring not only is an elastic element but also can guide and pass on the lateral and longitudinal force and moment. What's more, contact and friction between the plate spring pieces at the time of spring vibration will also have the effect of damping, so the leaf spring is a very important component that bears high load [3][4][5][6]. Although there are many leaf spring equivalent processing models at present, all of them have limitations.…”

Aiming at the processing problem of electric bus leaf spring equivalent model, the amendment leaf spring equivalent processing model is proposed after 3 kind leaf spring equivalent models are studied. This paper makes a comparison between the amendment leaf spring equivalent model and other models. Results show that the amendment leaf spring equivalent model not only considers the longitudinal force and lateral force of the leaf spring, but also avoids emergence the high stress area. So the amendment leaf spring equivalent model is more conform to the actual force situation of the electric bus frame, and it can provide the reliable constraint conditions for the next electric bus lightweight.

“…The suspension system is always working with the car frame, and has a great influence on the stiffness of the frame. To obtain the real stress distribution and deformation of the frame, the suspension system must be considered [2,3]. The suspension system is usually considered into the structure calculation and analysis.…”

In the analysis of car frame that considers the leaf spring, the three degrees of freedom model of leaf spring was proposed. It would be compared with the commonly used equivalent model at present. There is a clear difference between the impacts of the two models on the structure analysis of the frame. The stress and deformation of the frame with the three degrees of freedom model is greater than the commonly used equivalent model, and there is only a smaller value range of lightweight optimization. Through the comparison between the two models, it can be seen that the three degrees of freedom model can transfer force and moment of force in all degrees of freedom, which illustrates the stronger reliability of the three degrees of freedom model of the leaf spring.
