Rolling and sliding experiment table based on bidirectional excitation

Abstract

The invention discloses a rolling and sliding experiment table based on bidirectional excitation. The rolling and sliding experiment table comprises an experiment table bottom plate, a right support frame, a push plate and a left support frame are arranged on the experiment table bottom plate; wherein the right support frame and the left support frame are fixed on the experiment table bottom plate; the push plate is connected to the left support frame; a right friction wheel set is arranged on the left side face of the right support frame. A left friction wheel set capable of making contact with the right friction wheel set is arranged on the right side face of the push plate. The right friction wheel set and the left friction wheel set are adopted to carry out a rolling and sliding experiment through cylindrical contact wheels arranged on the right friction wheel set and the left friction wheel set respectively, in the rolling and sliding experiment, the two contact wheels make contact with the cylindrical surface through the cylindrical surface, and the right friction wheel set and the left friction wheel set control the rotating speed of the contact wheels through servo motors arranged on the right friction wheel set and the left friction wheel set respectively. Accurate load and multiple external excitation can be applied to the friction pair, and vibration, speed and torque of the friction pair can be collected in real time while the speed of the two friction pairs is controlled.

Problems solved by technology

[0006] However, in the actual motion of the rolling-sliding pair, it is not stable, but accompanied by external excitations in different directions and different loads

It is very important to study the influence of external excitation on the motion of friction pairs. None of the above disclosed inventions proposes a better way to carry out rolling experiments under external excitation conditions.
