art. no. 190466

The paper presents an approach that combines numerical and experimental techniques to evaluate the possibility of failure prevention of the structure of demolition robots. Based on a real example of the machine, the possibility of application and development of the proposed method was presented. The main problem when designing this type of machine is the negligible knowledge of how dynamic loads act during operation and how many times they appear. Underestimating the loads and their cycles when designing these types of machines can cause them to become damaged quickly. The method presented in the article allows to solve the problem of determining the key parameters needed in the evaluation of this type of construction such as loads, but also allows to determine the number of load cycles, which is particularly important for fatigue. The result presented in the article is a method that allows determining the fatigue of the structure of a demolition machine by combining numerical and experimental techniques.
