Abstract

The elevating equilibrator is used to control the elevating angel of the director of a rocket launcher. Based on an elevating equilibrator, a method for co-simulation is introduced with dynamic simulation software ADAMS and hydraulic simulation software EASY5. A three-dimensional model of the elevating equilibrator is developed with Solidworks and is imported into ADAMS. Furthermore, the hydraulic system model is established by EASY5. The interaction of mechanical system and hydraulic system is analyzed. The analysis indicates that the modeling method for co-simulation is effective and practical.

Highlights

  • The elevating equilibrator is a relatively complex action mechanism and used to control the elevating angel of the director of a rocket launcher

  • The virtual prototype of the elevating equilibrator is established with ADAMS and hydraulic system model is established with EASY5 respectively

  • Because of a large load generated when elevating equilibrator working, the dynamic simulation and analysis on elevating process of elevating equilibrator is of great significance [2]

Summary

Introduction

The elevating equilibrator is a relatively complex action mechanism and used to control the elevating angel of the director of a rocket launcher. The virtual prototype of the elevating equilibrator is established with ADAMS and hydraulic system model is established with EASY5 respectively. Co-simulation is achieved by dynamic data exchange between two models [1]. Because of a large load generated when elevating equilibrator working, the dynamic simulation and analysis on elevating process of elevating equilibrator is of great significance [2]. The elevating equilibrator model that is established and assembled in Solidworks software[3] is imported into ADAMS software and simplified on the basis of the dynamic relation. The dynamic simulation and analysis are in progress after the material properties defined and joints and load created.
