A new method of integrate simulation for the kinematics and dynamics analysis of complex mechanical system is presented in this paper. This platform of the method is based on Visual Studio 2005, MD ADAMS( Automatic Dynamic Analysis of Mechanical System) R3 and Pro/Engineer Wildfire 4.0. The experimental model is built with Pro/E, and then some functions of Pro/Toolkit are used to export file of parasolid format and coordinates of some specified Datum Points. Finally, the coordinates of these Datum Points are written into a CMD file (Commands file of ADAMS). A slider-crank mechanism is used as a numerical example to demonstrate the application of the method. It is shown that this approach is a much easier, faster than usual manual method especially for complex mechanical system which has a lot of Marker Points and constraints.

The tube-transferring car is a key part of transportation system for deepwater pipe-laying vessels. This paper covers the design of a tube-transferring car for deep sea pipe-laying, especially its lifting mechanism. Kinematics and dynamics analysis of the lifting mechanism is conducted. During dynamic analysis and calculation, the single degree of freedom mechanical system dynamic analysis method is used. The results show that the rotation angle of the lifting system has a direct impact on the lifting speed and driving force. The support reaction force in each kinematic pair which is calculated by choosing the single degree of freedom dynamics provides a theoretical basis for the design of the lifting mechanism, which is finally reflected in the selection of horizontal drive of the feeding machine and the related parameter design．

Weighting Methods

The weights of criteria in multi-criteria decision-making (MCDM) problems are essential elements that can significantly affect the results. Accordingly, researchers developed and presented several methods to determine criteria weights. Weighting methods could be objective, subjective, and integrated. This study introduces a new method, called MEREC (MEthod based on the Removal Effects of Criteria), to determine criteria’ objective weights. This method uses a novel idea for weighting criteria. After systematically introducing the method, we present some computational analyses to confirm the efficiency of the MEREC. Firstly, an illustrative example demonstrates the procedure of the MEREC for calculation of the weights of criteria. Secondly, a comparative analysis is presented through an example for validation of the introduced method’s results. Additionally, we perform a simulation-based analysis to verify the reliability of MEREC and the stability of its results. The data of the MCDM problems generated for making this analysis follow a prevalent symmetric distribution (normal distribution). We compare the results of the MEREC with some other objective weighting methods in this analysis, and the analysis of means (ANOM) for variances shows the stability of its results. The conducted analyses demonstrate that the MEREC is efficient to determine objective weights of criteria.
