AI Technical Summary
In existing abnormal noise test benches, the loading control requirements of the loading mechanism are high. Conventional gas springs cannot achieve free and precise adjustment of the load, resulting in high noise in the test environment and low test accuracy.
The pneumatic control module adjusts the air pressure difference of the cylinder group, and the air pressure of the cylinder group is controlled by the proportional valve and the air valve to achieve fine adjustment of the load. It is equivalent to a gas spring with a variable elastic coefficient for silent load loading.
It achieves quietness and accuracy in load loading, constructs a quiet testing environment, improves the accuracy of steering gear noise testing, reduces test noise, and enhances the reliability of test data.
