“…There are many works on experimental testing of colliding ships [263][264][265][266][267][268][269][270]. In all of them, the ships are scaled-down, sometimes significantly (1/45 [263], 1/35 [267], and 1/100 [268] scaled models). What really jumps out from these works is the difficulty in realizing the experimental tests.…”

Similitude theory allows engineers, through a set of tools known as similitude methods, to establish the necessary conditions to design a scaled (up or down) model of a full-scale prototype structure. In recent years, to overcome the obstacles associated with full-scale testing, such as cost and setup, research on similitude methods has grown and their application has expanded into many branches of engineering. The aim of this paper is to provide as comprehensive a review as possible about similitude methods applied to structural engineering and their limitations due to size effects, rate sensitivity phenomena, etc. After a brief historical introduction and a more in-depth analysis of the main methods, the paper focuses on similitude applications classified, first, by test article, then by engineering fields.

“…Jones 25 improved the scaling law about plates under low-velocity impacting which took into account the strain rate sensitivity of materials. Blok and Dekker 26 and Lehmann and Peschmann 27 presented the small-and large-scale models, respectively, to analyze the scaling law of ship collision. Jackson and Fasanella 28 investigated the 1/5-scale model composite fuselage concept for light aircraft which was used to study the flight loads and to design goals for improved crashworthiness, and through experiment and simulation study the consistency of the method has been proved.…”

This paper presents the scaled similitude rule for train collision, which follows the principle of acceleration consistency. If the similarity ratios of mass and initial impact speed of cars, crushing force, and initial length of the energy absorbing structures of trains with different proportions meet the requirements of the scaled similitude rule, the impact accelerations of each are considered to be consistent. The accuracy of the scaled similitude rule was analyzed by MATLAB simulation, which is based on the multibody dynamics theory. Before the analysis, the validation of the MATLAB model was verified based on the experimental model. Then the train-to-train collisions for two eight-car train sets with different similarity ratios were tested. Finally, the scaled similitude rule presented in this paper was found to be effective when the impact characteristics of the two models were compared.
