Bolt connecting quiet dynamic comprehensive experimental device

The bolt group connects the experimental device to perform experiments such as bolt static stress, deformation, stiffness, axial load, pre -tightening tightening, and other experiments.

Special test analysis software can perform related detection of bolt static and dynamic, and can compare the measured and simulation curve, and the curve can be printed.

All tested elements adopt a full bridge test circuit, and each str--n testing structure is stable, repetitive, and high accuracy.

A single -phase AC motor (220V power supply) is used to start the motor for a dynamic bolt experiment.

Dedicated test analysis software has multimedia teaching functions. Students can expl--n the experiments by experiments in the software and edit the test report through the software.

2. Experimental purpose

1. Understand the stress situation of the bolt connection during the tightening process.

2. Calculate the relative rigidity of the bolt and draw the stress deformation diagram of the bolt connection.

3. When verifying the load of the axial direction, the deformed rule of the pre -tightening bolt is connected, and the impact on the total pull force of the bolt.

4. Through the dynamic carrier experiment of the bolt, change the relative stiffness of the bolt connection, observe the changes in the amplitude of the bolt, to verify the measures that increase the intensity of the bolt connection.

3. Experimental project

1. Basic bolts connect to quiet dynamic experiments.

2. Increase the static and dynamic experiments of the bolt rigidity.

3. Increase the static and dynamic experiments of the rigidity of the connection.

4. Use the static and dynamic experiment of elastic pads.

1. System summary

The system constructs the environmental control model, vehicle control room, and environmental control equipment room of the three -dimensional virtual station, which provides a situational operation tr--ning function for the composition, operation, d--ly operations, and non -normal operating operations of the station.

Virtual simulation teaching system

Machinery tr--ning security education virtual simulation software: This software is developed based on UNITY3D. The software is in the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design Basic assessment and experiments, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius, and the experimental process is accompanied by a three -dimensional robot dialog box reminder.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood color picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice. Essence

B. Machinery safety protection device experiments are divided into protection device experiments such as security ch--n switches, safety curt--ns, safety cushions, safety laser scanners, etc. Optional categories (safe input, safety control, safety output, other), manufacturers, products, products, products, products, products, products, products, products, products List (safety ch--n switch, safety curt--n, safety cushion, safety laser scanner, safety controller, safety relay, safety guardr--l). The installation location has a blue flash frame reminder. Experimental process: Choose a safe guardr--l and install, select a safety ch--n switch (or select a safe light curt--n, safety cushion, safety laser scanner) and install, select the safety controller and install it to the electrical control box Select the safety relay and install it to the electrical control box, click the start button on the electrical control box. If you enter the dangerous area, the system will prompt alarm and stop working. Select the reset button on the electrical control box to stop.
