Abstract
Multibody Simulation Software has become widely used in different industrial fields to test design solutions in a cheaper and faster way.
During the past years, CETENA developed several applications in the naval field using these kinds of tools: some of these applications are described in this paper to demonstrate the capabilities of this approach to evaluate the design solution
Introduction
Multibody Simulation Software represents an important tool to perform various kind of engineering evaluations of different design solutions in different fields.
These tools allow the user to realistically simulate the behaviour of complex mechanical systems and to rapidly analyse various design alternatives, until the best one is matched.
The rigid bodies are defined into a synthetic environment, linked with joints representing the physical constraints, and moved by forces according to physical laws.
Multibody simulation tools were largely used in automotive industry, and then in the aeronautic and railway fields: several years ago CETENA and Fincantieri started to investigate some aspects of naval engineering with a multibody approach.
The results of such applications showed the possibility to carry out study of naval issues. CETENA and Fincantieri have been dealing with many investigations such as:
• Checking movement capabilities of crane installed on board
• Lifeboat launching verification
• Anchor-Hawse system verification
• Dock mooring verification
• Slipway launching
