Cylinder-in-cylinder structure for linear motor machine

The invention discloses a cylinder-in-cylinder structure (100) for a linear motor machine. The barrel-in-barrel structure includes (a) an outer metrology frame (20) for responding to maintaining a payload (50) and allowing the payload (50) to move thereon; (b) an inner force frame (10) enclosed within the hollow cavity (22) of the outer metrology frame (20) and responsive to transmitting any reaction force to be exerted by the payload (50) to the bottom of the inner force frame (10) wherein the bottom end of the inner force frame (10) is mounted to the bottom end of the outer metrology frame (20) and such mounting is positioned to the ground. The internal force frame (10) transmits any reaction force applied by dynamic motion generated by the linear motor machine directly to the bottom of the internal force frame (10), thereby minimizing or stabilizing vibrations caused by linear motor motion. 本发明公开一种用于线性电动机机器的筒中筒结构(100)。所述筒中筒结构包含(a)外度量框架(20)，所述外度量框架用于对维持有效负载(50)和允许所述有效负载(50)在其上移动做出回应；(b)内力框架(10)，所述内力框架被包围在所述
