Abstract

The invention discloses a device and a method for testing lateral impact friction. The device for testing lateral impact friction factors comprises a pneumatic pump, a pneumatic impact device, an arc-shaped rail, an incidence column, a clamp, a support, truckles, an acceleration sensor, a speed sensor, a first strainmeter, a second strainmeter, a first test sample, a second test sample, a transmission column, a belt pulley, a shock absorber, a belt, a variable-frequency motor, a signal acquisition device and a computer. Due to the arrangement of the truckles at the bottoms of the pneumatic impact device and the support, the pneumatic impact device and the support can move on the arc-shaped rail so as to regulate the impact incidence angles of the test samples. Lateral impact friction of materials can be tested by the device. The shapes of the test samples which are used in the invention can be changed, so that the lateral impact friction properties of different types of materials can be tested.

Description

technical field [0001] The invention relates to a side impact friction testing device and a testing method, in particular to a device and method capable of directly measuring impact force, impact torque, impact velocity, impact acceleration and friction factor during material side impact. Background technique [0002] Impact friction is surface friction caused by the dynamic impact of two solid surfaces. In various types of machinery, many parts are subjected to different degrees of impact and friction. For example, during the working process of a ball mill in the coal mine field, there are dynamic side impact frictions between steel balls, rollers, and materials. The test device for the impact friction characteristics of materials during side impact has not yet been found, which brings great inconvenience to the side impact friction test. [0003] Therefore, it is necessary to develop a device that is easy to operate and can directly measure the impact friction characteris...
