A new type of mineral car arrester, designed for transportation in the inclined shaft rail undermine, includes three degrees of freedom and seven links, to achieve the functions, like a one-way retarder, automatic resetting. The arrester achieves opening and closing functions by air cylinder driving and gravity resetting, and it arrests the car by the way of directly stopping the slipping car. Meanwhile, a buffering system installed under the track, including three buffering springs, as flexible energy absorption equipment absorbs the striking energy. This paper introduces the dynamics analysis of the impact behavior for the car arrester in detail, so that the impact dynamics for the ideal function of car arrester can be obtained by conclusion. The oscillatory differential equations freedom kinematics equations of the impact system are developed. The mineral car and arrester, under position-type nonlinear forces, are simplified to single mass bodies. The data such as the maximum spring force, maximum amplitude, the time and the numbers of impact are achieved by Mathcad, to solve the dynamic equations and analyze the motion law of the mine car after the impact. Then, the conclusion can be obtained that there are some reliability redundancies in the car arrester. Meanwhile, the three key components of the car arrester are analyzed in ANSYS finite-element analysis software. According to the analysis, it is confirmed that design of the structure and size parameters of the car arrester meets the security and functional requirements.
