Detailed Description
In order that those skilled in the art will be able to fully practice the present invention, it will be further described with reference to the accompanying drawings and specific examples.
A method for testing the thrust of the operating handle of driver controller includes fixing the driver controller, applying a thrust F gradually increasing from zero to the operating handle, and obtaining the maximum thrust F when the operating handle is driven by the action force of the thrust F to rotatemax(ii) a Then the operating handle is kept to rotate to the limit position in a constant speed state, and a plurality of discrete maintaining thrust F are obtained at the stagenCalculating a plurality of discrete holding thrusts FnAs an effective sustaining thrust F of the operating handlet. Generally, the thrust required to push a certain device is larger than the thrust for maintaining the device in a uniform motion, so when the thrust of the operating handle is tested, the maximum thrust F for pushing the operating handle to start rotating is needed to be tested firstlymaxDetecting, wherein the specific implementation process is that after the operating handle starts to rotate, the instantaneous thrust at the moment is obtained, and the instantaneous thrust is the maximum thrust Fmax. When the operating handle starts to rotate, the thrust F of the whole process is continuously detected, and the effective maintenance thrust F can be obtained after averaging a plurality of discrete valuest. Maximum thrust F to be obtainedmaxAnd effectively maintaining the thrust force FtAnd comparing the standard value with a standard value to calculate an error, namely judging whether the thrust of the operating handle meets the technical standard, wherein in the embodiment, the allowable error needs to be within +/-15N.
When the pushing force F is applied to the operating handle, the application direction and the application position determine whether component force and moment conversion is needed after the pushing force F value is finally obtained. For example, when the direction of application of the pushing force F has a certain angle with the tangent of the arc of rotation of the operating handle, the pushing force F needs to be converted into a component force along the tangent of the arc of rotation of the operating handle, that is, a cosine component of the angle. When the thrust F is applied at a distance from the end of the operating handle, the torque needs to be converted according to the length of the entire operating handle and the actual distance from the applied part to the end of the operating handle. Although the conversion of the component force or the moment can obtain the effective component force which is applied to the end part of the operating handle and is along the tangential direction of the rotating arc of the operating handle, the conversion is needless, so that the component force or the moment is applied to the end part of the operating handle and is along the tangential direction of the rotating arc of the operating handle when the thrust F is applied, the thrust F can be directly measured without conversion, the detection efficiency is improved, the error loss of the thrust F in the application direction and the application position is avoided, and the test precision is improved. And thrust F is exerted at the end of the operating handle, and also accords with the actual working condition, because the action part when the operating personnel pushes the operating handle is also the end of the operating handle in the actual working condition.
In order to ensure that the pushing force F can be always applied to the end part of the operating handle along the tangential direction of the rotating arc of the operating handle in the application process, a preferred embodiment is to apply the pushing force F to the end part of the operating handle through a fixed part in the force measuring assembly 2.
