Introduction
Standard Overview
GB/T 37242-2018 specifies the determination method of sound power level of industrial robots and service robots, covering key technical indicators such as test environment, instrument requirements, and operating conditions. The standard divides robots into two categories: industrial robots and service robots, and adopts different test accuracy levels (industrial robots level 3, service robots level 2).
Comparison of core test requirements
| Test dimension | Industrial robot | Service robot |
|---|---|---|
| Background noise difference | ≥3dB | ≥6dB |
| Environmental correction limit | ≤7dB | ≤4dB |
| Test instrument level | Level 2 and above | Level 1 and above |
| Benchmark body setting | Circumscribed square of maximum arm span | Minimum envelope of motion range |
Analysis of key technologies
1. Specifications for setting reference body
For industrial robots with arm span, a circle with the maximum arm length as the radius is drawn, and its circumscribed square is taken as the length and width of the reference body; for service robots, the reference body is determined according to the minimum hexahedron of the actual motion range. In special cases:
- Cleaning robots need to be tested on a 1m×1m wooden floor
- Small service robots (length and width ≤ 0.5m and height ≤ 0.7m) use a hemispherical measuring surface
2. Test point layout plan
Typical case: A six-axis industrial robot has an arm span of 1.8m and a height of 1.2m. Its test point layout is:
- Base body size: 1.8m×1.8m×1.2m
- The four test points are 1m away from the boundary of the base body
- The test height is (1.2+1)/2=1.1m
Implementation suggestions
Test environment construction
Should meet the following requirements:
- Temperature 10-35℃, humidity 30-70%
- Hard and smooth ground (reflection coefficient ≥0.9)
- Industrial robot test distance from the wall ≥2m
Troubleshooting
| Problem phenomenon | Solution |
|---|---|
| Background noise exceeds the standard | Choose nighttime testing or install a soundproof cover |
| Mobile robot trajectory deviation | Use laser guidance to ensure linear motion |
| Multiple sound source interference | Test each component separately in different time periods |
Key points for report preparation
Must include:
- Calculation process of background noise correction value K1A
- Determination method of environmental correction value K2A
- Original data and average value of each test point
- Temperature and humidity records of the test site
