The offshore platform is an artificial island for drilling and oil exploitation in the offshore waters far away from the port.The harsh environment,such as sea wind,waves,currents and earthquakes,causes strong vibration of the offshore platform,which may lead to the failure of the platform equipment and endanger the life of the operators.In order to improve the seismic ability of the offshore platform,a discrete electronic control handle design scheme is proposed,using mechanical locking structure for positioning.The design scheme is verified by small batch machining and fatigue life experiment.The results show that the electronic control handle with mechanical structure can meet the shock resistance requirements.After one million times of accelerated fatigue life test,this electronic control handle structure can still be quickly and accurately positioned,and the change of gear feedback force before and after the test is small.The results show that the design scheme of discrete electronic control handle with mechanical locking structure for positioning can effectively avoid the problem of gear skipping and disengagement due to the strong vibration of the offshore platform.It shows high reliability and stability,which can meet the use requirements of the offshore platform electronic control handle.
