Abstract
Disclosed are a sensor for measuring seating force of an engine intake and exhaust valve and a measuring method. The sensor comprises a mounting boss, a force bearing element, a piezoelectric element, an annular thin-wall shell and an annular diaphragm with a T-shaped section. Meanwhile, the present disclosure also provides a measuring method by using the sensor. The sensor is simple in mechanism and convenient to use, has certain universality, and can realize the measurement of the impact load of the engine intake and exhaust valve.
Claims10
A sensor for measuring seating force of an engine intake and exhaust valve, comprising a mounting boss, a force bearing element, a piezoelectric element, an annular thin-wall shell and an annular diaphragm with a T-shaped section, wherein the upper portion of the mounting boss is of a hollow cylinder structure, and the lower portion of the mounting boss is of a hollow circular truncated cone structure;
- the force bearing element is a circular ring with a right trapezoid section;
- the piezoelectric element is pressed and fixed through the combined action of the annular thin-wall shell, the annular diaphragm with a T-shaped section and the force bearing element;
- and the mounting boss, the force bearing element, the piezoelectric element, the annular thin-wall shell and the annular diaphragm with a T-shaped section are connected with one another.
