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

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
