Problems solved by technology
However, the electro-hydraulic load simulator has a large pollution and is difficult to maintain, so it has been gradually eliminated.
[0004] In addition, the current electric load simulation equipment on the market has a maximum loading torque of 500Nm and a loading frequency of 20Hz. Due to limitations in loading torque and frequency, the response speed is slow and it is impossible to accurately control the loading torque.
