Analýza bezpečnostního pásu v leteckých sedadlech

Abstract

This thesis deals with mathematical modeling of crash test aircraft seats. The main goal is to determine time course of the reactions in anchoring points of lap belt and their maximum values. The thesis was awarded on the basis of practical requirements of company IDEA AIR s.r.o. Results will by reflected in development of a new type aircraft seats. The first part deals with the testing of aircraft seats, types of seat belts and their materials. The next part deals with the mathematical modeling of dynamic problems using the finite element method (FEM). Derived procedures are further verified in several examples and implemented in the Python programming language. Own calculation algorithm is applied to the analysis of safety belt in the final part. Results are compared with the simulation performed in commercial software LS-DYNA.
