High-altitude rescue is an issue that always receives great attention. Using rescue winches on the outside of structures is a popular solution. During the rescue process, when the brakes stop, it will affect the human body, causing discomfort, especially when the rescue subjects include the elderly and children. The purpose of the research is to find a reasonable brake structure solution and parameters to improve performance, allowing for increased speed while still ensuring smooth acceleration when braking and controlling shock. This article develops calculation formulas describing the braking process and develops a method for selecting design parameters to control the braking process including spring deformation, spring stiffness, braking time, etc. The study uses the orthogonal matrix, analyzing the influence of parameters on the response function, and spring stiffness. Applying numerical testing to the design to increase the speed by 300%, the result is that the acceleration when braking is reduced by 67.75% compared to the previous study, and the shock in the range is smaller than the allowable value.
