PC controlled shock absorber performance testing machine

Shock absorber performance testing machine WSD-8762B (indicator machine)

First, the scope of application: The shock absorber performance tester can test the performance of the front (rear) shock absorber for motorcycles or electric motorcycles. The test bench can be used for the factory inspection of the products of the shock absorber manufacturer and the incoming inspection of the shock absorber by the vehicle factory

2. According to the standard:

1) Q/YDJ J028-2013 Shock Absorber for electric vehicles (hydraulic straight cylinder type)

2) QC/T62-2007 Technical conditions and test methods for shock absorbers for motorcycles and mopeds

3) Q/YDMS-ZG-45 product parts quality standard B

Iii. Test items:

1) Damping characteristic test

a) indicator characteristic test

2) Static friction force test

Four, the main technical parameters:

1) Damping characteristics test, static friction force test parameters:

a) Test conditions: meet the multi-condition test

b) Sensor capacity: 20KN

c) Sensor grade: 0.5

d) The force measurement error is less than 3%

e) The displacement measurement error is less than 1%

f) Force control rate adjustment range: 0.005--5%Fs/s;

g) Force control speed control accuracy: when the speed is < 0.05%Fs, it is within the set value of ±1%; Rate > 0.05%Fs is within the set value of ±0.5%.

h) Deformation rate adjustment range: 0.02-5% Fs/s;

i) Deformation rate control accuracy: when the rate is < 0.05%Fs, it is within the set value of ±1%; When the rate is greater than 0.05%Fs, it is within the set value of ±0.5%.

j) Displacement rate control accuracy: when the rate is < 0.01mm/min, it is within the set value of ±1%; When the speed is > 0.05mm/min, it is within the set value of ±0.2%.

k) Test speed: 0.1m/ S-1m /s can be set

l) Power source: servo motor + planetary reducer

m) Transmission mode: belt wheel + ball screw drive

5. Software and Software operation interface:

1) The software can be used in Windows98/2000/XP, and the user interface is presented in the same Chinese style as Windows

The window system. All test operations can be done on the computer screen with mouse input.

2) Displacement control.

3) Automatic program control can choose a variety of control modes.

4) Automatic programmed intelligent expert system. Automatic process steps up to 50 steps.

5) The software has a hierarchical management permission setting function to further ensure the safe use of the software. The software has three levels of management rights, from low to high, general operators, senior operators, management personnel, respectively by their own passwords to log in.
