The purpose of the stand is to conduct stationary tests of power plants of caterpillar and wheeled vehicles with engine power up to 3200 hp. By definition of the following main indicators:
At the stand, it is possible to conduct long-term tests of power plants in modes that simulate movement along the medium-crossed terrain at ambient temperatures up to + 55 ° C of the following machines:
Loading devices are the main elements of the stand.
The composition of the left or right loader includes:
Loading devices can be assembled according to 5 schemes, differing from each other by the number of gear ratios depending on the setting of the adapter shaft, one or two multipliers, or a totalizing reducer. When choosing a scheme, the type of testing carried out, as well as the speed, traction, mass and overall parameters of the machine are taken into account.
Technical characteristics of bench loading devices when assembling them according to 5 schemes.
|# schema||For machines with a driving wheel radius of 0.4 m||Gear ratio of loading device|
|Maximum speed, km / h||Range of simulating the mass of the machine, t|
The information and measuring equipment of the stand consists of two personal computers, a rack-matching unit for 96 measuring channels, two printers and a demonstration screen. This complex allows for real-time tests with a frequency of 1 to 100 Hz to receive and process up to 0.5% of the signals coming from the sensors installed on the machine. With the help of special software, the information is displayed graphically on the monitors, as well as printing the test report on the printer and saving it to a file on the hard disk of the computer.
