Problems solved by technology
[0003] However, at present, there are very few test equipments specially designed for valve motion testing at home and abroad. In the existing valve motion test equipment, there are problems such as inconvenient installation of samples, poor centering adjustment accuracy, time-consuming, difficult adjustment of oil supply, and data acquisition. Low storage rate, heavy workload of subsequent data processing, etc.

The invention provides an air valve motion testing stand. The air valve motion testing stand comprises a stand, a motor, a torque sensor, a laser displacement sensor, a sample member mounting board and an oil supply system, wherein the motor is mounted on the stand and is used for driving a detected sample member to rotate according to the set speed, the sample member mounting board is used for mounting the detected sample member, the torque sensor is connected with the motor and the detected sample member and is used for measuring torque and a rotation angle of an air valve control shaft of the detected sample member, the laser displacement sensor is used for measuring displacement of the air valve of the detected sample member at each instant moment, and the oil supply system is used forproviding cycle oil with certain pressure and temperature for the detected sample member.
Description
technical field [0001] The invention relates to the technical field of automobiles, and in particular to a valve motion test bench. Background technique [0002] The valve movement test bench is used for the engine valve movement test, and the valve mechanism of the engine is studied by testing the characteristics of the valve movement. The physical quantities tested by the valve movement test bench include valve displacement, camshaft torque and rotation angle. The velocity and acceleration can be converted from the displacement and time relationship of the valve movement. These test quantities are drawn into a test curve for analysis by researchers. [0003] However, at present, there are very few test equipments specially designed for valve motion testing at home and abroad. In the existing valve motion test equipment, there are problems such as inconvenient installation of samples, poor centering adjustment accuracy, time-consuming, difficult adjustment of oil supply, a...
