| 摘 要： | According to ZBJ65015-89 standard about noise level testing method of woodworking toot, the noise testing for MJg0# and MJCl125 precision panel saws was conducted by using model ND2 precision soundqevel apparatus and double frequency wave filter. The testing results showed that the unloaded running noise source of precision panel saw was mainly from main saw blade and its aeromechanic noise was the largest. The rotating speed was determined as an important factor to impact dynamic characters of precision panel saw as the unloaded running noise increased along with speed increasing. For reducing noise of precision panel saw, the first important way is to reduce the aeromechanic noise produced by main saw blade rotating at high speed; based on assuring the processing precision, choosing tow speed is a better way to drop dawn noise; from the view of design, the diameter of clamping lid is better of half of outer diameter of main saw blade.

| Abstract: | According to ZBJ65015-89 standard about noise level testing method of woodworking tool, the noise testing for MJ90# and MJC1125 precision panel saws was conducted by using model ND2 precision sound-level apparatus and double frequency wave filter. The testing results showed that the unloaded running noise source of precision panel saw was mainly from main saw blade and its aeromechanic noise was the largest. The rotating speed was determined as an important factor to impact dynamic characters of precision panel saw as the unloaded running noise increased along with speed increasing. For reducing noise of precision panel saw, the first important way is to reduce the aeromechanic noise produced by main saw blade rotating at high speed; based on assuring the processing precision, choosing low speed is a better way to drop dawn noise; from the view of design, the diameter of clamping lid is better of half of outer diameter of main saw blade. |
