AI Technical Summary

Problems solved by technology

[0004] The currently known load simulators have complex structures, large volumes or limited carrying capacity, and cannot accurately realize the dynamic simulation of the load, let alone simulate the inertia of the load end

Most of the existing load simulation devices do not consider the simplicity and convenience of installation, disassembly, replacement and operation and the comfort of the test personnel; at the same time, the existing load simulation devices do not consider the stress of the main body of the test bench and how to effectively The problem of reducing the radial unbalanced force can be minimized, which cannot be ignored in the case of high power and large moment loading; in addition, the existing load simulators have little consideration for the simulation of the inertia of the rudder surface, and most of them can only simulate the fixed inertia It is not even possible to simulate the inertia
