The above device and method can be used for electric cylinder erecting system loading and performance testing.

Description

technical field [0001] The invention relates to an electric cylinder erecting technology, in particular to an electric cylinder erecting system loading and performance testing device and testing method. Background technique [0002] Electric cylinders are directly driven by motors. Compared with hydraulic cylinders, they have the advantages of clean energy, simple system composition, high control precision and good dynamic characteristics. They are widely used in small and medium power drive mechanisms. However, for larger loads, in order to reduce the thrust of a single electric cylinder while balancing the thrust and preventing rollover, it is usually necessary to use dual-cylinder drive or multi-cylinder synchronous drive. [0003] In the initial stage of system design, in order to quickly verify the control strategy, the test device is required to automatically complete the system loading test and test the control performance of the dual-cylinder drive or multi-cylinder ...
