Description

technical field [0001] The invention relates to a principle prototype and a method thereof, in particular to a principle prototype and a method for applying a load in a hydraulic manner and measuring the displacement of a device. Background technique [0002] With the continuous progress and development of science and technology, more and more high-techs are constantly being explored and promoted. Before making innovative or forward-looking machines, trial-manufacture some prototypes or test devices and conduct simulation tests on them, not only to find out the defects or deficiencies of the prototype or test device, but also to simulate actual working conditions to impose on the prototype or test device For constant load or linear load or closed-loop feedback load, the maximum power and optimal working conditions of the prototype or test device can be calculated through test data, which provides a strong guarantee for the actual development of the finished machine or finish...

Problems solved by technology

In this method, the magnitude of the clamping force can be measured, but the magnitude of the friction force cannot be measured, and with the different degrees of wear of the friction plate, the friction force will also change under the same clamping force condition, and this method is used for a long time. It will cause the friction plate to heat up rapidly, causing unpredictable changes in friction, so this method is also a rough measurement method
