I.  OVERVIEW 

 

1.  Overview of the project 

 

1.1 

Korea Aerospace Research Institute (hereinafter referred to as “KARI”) is located 

at Daeduk Research Complex, 140 km south of Seoul. 

 

1.2 

KARI has a satellite assembly, integration and test center (hereinafter referred to 

as “AITC”) for joint use by corporations and research institutes for the purpose of 

the effective development of domestic satellites. And basic facilities and 

equipment for satellite assembly and test have been supplied, installed and used. 

 

1.3 

The purposes of this project is To design the seismic mass(reaction mass) and 

produce the detailed drawings for fabrication 

 

1.4 

All the descriptions in this RFP are minimum requirements and the supplier can 

suggest the better one to improve the overall performance and cost. But in this 

case, the proposal should clearly indicate the improvements from KARI’s 

requirements. 

 

2.  Requisites of participants 

 

2.1  The participants shall also have experience of manufacturing, integration, 

installation and operation for the 3m x 3m T-Film Slip table vibration system 

equipped with electro dynamic shaker. 

 

3.  Scope of the contract 

 

3.1 

The Contract shall supply the following; 

 

  FEM model and Analysis report for seismic mass 

  Detailed engineering drawings for fabrication

II.  Technical Requirements 

 

1.  Total System Configuration 

 

To increase the horizontal shaker capability, 3mx3m slip table system will be designed 

and built. Before the installation of the slip-table system and vibration shaker, seismic 

mass should be designed to support dynamic load during the vibration test
