Abstract

According to the functions of parametric modeling and analysis from ADAMS, this thesis was established a parametric simulation model in order to optimize the rated output power of electric cylinders according to the real field environment. First, the variable which could affect sensitivity of the output variables was chosen by the electric cylinder’s elongation which was obtained through loop vector method. Then this thesis tried to get the optimum optimization design parameters through the simulation, and the change of rated output power affected by the change of parameters, meanwhile, made a filter and calibration of parameters which have greater influence on sensibilities. The goal of design could meet the qualification with less work load and faster speed. It is concluded that the change of the location parameters affects the rated output power.

Highlights

Nowadays, the parametric design was an emphasis in the study of CAD [1]
The MSC ADAMS possesses the functions of parametric modeling and analyzing in order to improve the efficiency of mechanism design and shorten the designing period
The document [2] regarded the minimum driving angles as an optimization goal, and the lengths of links are parameterized via ADAMS by creating design parameters

Summary

INTRODUCTION

The moving platform and middle supporting platform were connected by structure of frames This scheme increases space to install equipment, but decreases the height of equipment's center of gravity to improve the equipment stability as well. Because of the motion platform moved by the way supported by middle and moved by two electric cylinders and maintenance-free bearing in the middle support nearly most loads, it reduces the demand for electric cylinder's output torque. It meets the low power requirements which chosen in field environment test
