Abstract

Demolition and collapse dynamics of steel machine structures and optimum design are studied. Beam and telescopic elements are tested to plastic collap- se and recorded using video and PC and analyzed with nonlinear FEM and analytically. Collapses of some structure are simulated using a two-dimensional mechanism program models with nonlinearized springs and stiff bodies. The methodology of optimum design is considered in the case of a telescopic crane mechanism. The goal of maximizing customer satisfaction on the cost and tech- nical performance is shown useful. The technical goal is defined as minimizati- on of the top event probability of total collapse at demolition load. 1 Introduction Collapses and crashes of machines are undesired events called top events. It is good opt
