6DOF Electric Motion Platform

It does not need complex basic construction, therefore the investment in plant and ground is small and easy to keep clean.

 The advantages of 6 DOF electric platform Compared to traditional hydraulic motion systems, electric motion systems have unparalleled advantages:

Low requiements for the plant and other technical facilities.Electric platform does not need complex basic construction, therefore the investment in plant and ground is small and it is easy to keep the ground clean. Lower cost of the installation and maintanance and because of simple configration, electric motion system can be installed within 2-3 days. The electric motor is usually in a sealed state,so there is no need for extra maintenance in the whole service life of the simulator. The security has improved.Compared to hydraulic platform, hidden trouble of electric platform greatly reduced. Reliability has improved. The average malfunction time of electric platform is extended,so it can meet the 7 daysX24hours training reqiurements of the customer. Capability of the simulator has improved. Electric motion system has faster reaction time, greater rate of change of acceleration, shorter system delay. Electric motion system has better frequency response characteristics,so it can simulate the dynamics better. Less power consumption. Power consumption in training is generally 25% -30%.of hydraulic system of the same load.

2.The composition of electric motion systemThe structure view of 6 DOF platform. As shown in Figure11.Mechenical structure including:Ground frame structure includes a support plate and three actuating cylinder supports;  6 electric actuating cylinders of 24-inch stroke,mechanical brake, position feedback encoder and absolute position switch; upper connecting hinge support< 2.Control box including:

6 digital amplifiers;   6 braking resistor;  User interface digital I / O interface;  emergency power out circuit and I/O interface   all system cables

3 Technical indicators of electric motion system 1. Limit position, velocity and acceleration indicatorsThe following indicators all takes geometric center of the motion platform(MPC) as calculating reference point.The system equipped with the corresponding load.The definition of the geometric center is the geometric center of the upper platform triangle.
