Friction exploring experimental equipment

Abstract

The invention relates to the technical field of experimental equipment, in particular to friction exploring experimental equipment. The friction exploring experimental equipment comprises an outer cover, wherein a rotating motor is arranged at the top end of the side wall of the outer cover; a spring dynamometer is adhered to the inner wall of the left side of the outer cover; a supporting plate is arranged inside the outer cover. Through the rotating motor and the supporting plate which are mounted on the experimental equipment, the effect of relative uniform movement of an experimental slideblock is achieved and occurrence of the situation that an experiment is interfered by human factors due to conventional manual pulling of the slide block is avoided; through a lifting mechanism and the supporting plate which are mounted inside the experimental equipment, the effect of conveniently adjusting the contact surface pressure is achieved and occurrence of the situation that the contactsurface pressure can be changed only by constantly changing the slide block in the conventional experimental equipment is avoided; in a way of fixing the spring dynamometer on the experimental equipment for pulling the supporting plate, the effect of reading the reading of the spring dynamometer conveniently is achieved and occurrence of the situation of an reading error due to movement of the spring dynamometer in the conventional technology is avoided.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to an experimental equipment for exploring friction force. Background technique [0002] Friction refers to the force that hinders relative motion (or hinders relative motion tendency) when an object moves relatively (or has a tendency to move) on the surface of another object. However, primary and secondary school students still have many doubts when they first come into contact with the concept of friction, because there are many factors that affect friction, such as: the pressure of the contact surface, the roughness of the contact surface, the size of the contact surface, and the composition of the contact surface material. , in order to make it easier for students to deeply understand the factors that affect friction, the experimental equipment for friction exploration came into being. [0003] The existing experimental equipment has the following defects: 1. It...

Problems solved by technology

[0003] Existing experimental equipment has the following defects: 1. It is disturbed by human factors, such as: the movement of the object should be kept at a constant speed during the measurement process, and it is difficult to move at a constant speed no matter whether it is pulled by manpower or a code or a pulley; 2. The contact surface The pressure of can only be changed by changing the slider. In view of this, we propose an experimental device for friction exploration
