Using of Co-simulation ADAMS-SIMULINK for development of mechatronic systems

This paper deals with an efficient technique for the development of mechatronic systems. Individual parts of such system as mechanics, actuators, sensors, control system, etc. are designed in several passes through V-model with respects to mutual feedbacks. Based on this methodology the developed system is made as a virtual prototype and can be tested and simulated using co-simulation technique. The ADAMS and SIMULINK co-simulation is used and it is based on direct embedding of dynamic model of the mechanical system with sensors and actuators implemented in ADAMS into MATLAB environment to a control system design and a virtual prototype model tuning. So the complex model of mechatronic system applies the same implementation for design, simulation and testing.

Electromagnetic Vibration Power Generator

This paper shows an alternative for supplying wireless sensors with energy: electrical power is generated from an ambient mechanical vibration by use of a vibration power generator. As the generator is excited by ambient mechanical vibration, its construction produces a relative movement of a magnetic circuit. This movement induces a current into an electrical coil due to Faradays law. For aeronautical applications like e.g. helicopters, the generated power of around 5 mW provides enough energy to supply a wireless sensor.

Simulation of Vibration Power Generator

This paper deals with the simulation of a vibration power generator that has been developed in scope of the European Project “WISE”. The vibration power generator generates electrical energy from an ambient mechanical vibration. The generator is a suitable source of electrical energy for wireless sensors which operate in vibration environment. When the generator is excited by mechanical vibration, its construction produces a relative movement of a magnetic circuit against a fixed coil. Thereby the movement induces voltage on the coil due to Faraday’s law. This paper describes the modelling of the vibration power generator in Matlab/Simulink.

Simulation modelling of mechatronic system with flexible parts

This paper deals with a simulation modelling of developed mechatronic systems, which contain a flexible behaviour of individual mechanical parts. The developed process usually contains ideal models of rigid mechanical system. The presented simulation model consists of a mechanical multi-body system with flexible parts, models of actuators, sensors and control and it is used for the development of this system with respect of the mechatronic approach. The dynamic behaviour of the whole model is analysed and the flexible properties of the mechanical system are considered. The co-simulation technique is used for this task in which the multi-body model of the developed system in ADAMS is controlled by a model in Matlab/SIMULINK environment. The complex model of the developed mechatronic system can be used as the virtual prototype of the real system and its behaviour can be tested and analysed.

Simulation Modelling and Control of Mechatronic Systems with Flexible Parts

This paper deals with a simulation modelling of mechatronic systems with flexible parts. The presented approach can be used for a development of the mechatronic system which contains flexible parts. Deformations of these flexible parts affect behaviour of the whole mechatronic system. The flexible parts are included in the most of engineering applications and during a development cycle the behaviour of such parts is usually assumed as the behaviour of rigid parts and spring elements. The presented simulation modelling of the mechatronic system includes the behaviour of a multi-body system with the flexible parts using co-simulation techniques and it can be useful for a control design and a better prediction of the mechatronic system behaviour especially in systems where a deformation of flexible parts is significant for a correct operation of the system.
