Problems solved by technology

However, it can only provide a single positive or reverse rotation excitation, which makes it impossible to test various limited-angle rotary actuators. It is even more difficult to test high-torque limited-angle rotary actuators, which eventually leads to

Abstract

The invention discloses a reciprocating rotation excitation stand system which is characterized in that a reciprocating rotation excitation system is composed of a linear actuating vibration table, a motion conversion device, and a turning torque rising device, the motion conversion device converts the vertical reciprocating linear excitation formed by the linear actuating vibration table into vertical reciprocating rotation excitation, the turning torque rising device converts the vertical reciprocating rotation excitation into horizontal reciprocating rotation excitation, the torque and the rotation travelling of the horizontal reciprocating rotation excitation can be increased and reduced in the turning torque rising device, and an excitation control module measures the vibration amplitude and the linear exciting force of the reciprocating rotation excitation system at the same time. The reciprocating rotation excitation stand system is suitable for the characteristic test of a large-torque limited angle actuator and can perform the vibration control experiment test based on passive/active/half-active rotary actuator.

Description

technical field [0001] The invention relates to the technical field of testing a rotary actuator and its vibration control system, in particular to a reciprocating rotary excitation system for a reciprocating rotary actuator. Background technique [0002] There are many types of testing instruments for rotary actuators, such as torque wrenches and torque meters. Torque wrench is a kind of wrench with adjustable torque, pre-adjust the torque, and then tighten the object. Using this feature, it can be used as the most simple and practical rotating excitation tool or torque testing instrument, but the accuracy of this instrument is low , The rotary excitation that can be applied is small and the range is very limited. The torque meter is an accurate measurement instrument for the tightness of the lids of various containers such as medical equipment, cosmetics and beverages, the tightness of screws, the torque of valve opening and closing, and various torques. It is also widely...
