Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present invention can combine mutually.
Below with reference to accompanying drawing, embodiments of the invention are done to concrete explaination.
A kind of operator's compartment shock-reducing and noise-reducing structure of the embodiments of the invention as shown in Fig. 1 to 8, is applicable to the operator's compartment of quarry tipper, adopts and controls noise source, passive noise elimination, controls the means such as noise transmission path and carry out comprehensive damping noise reduction.
As shown in fig. 1, the general thick sheet metal component of 1.5～2.0mm that adopts of operator's compartment covering 1.In the time that extraneous environmental noise is 100dB (A) left and right, the sheet member of 1.5～2.0mm is very easily penetrated by acoustic energy, its noise insulation factor wretched insufficiency, and sheet member self vibration can produce equally quadratic noise and provides certain contribution to the total sound pressure level in operator's compartment inside.In conjunction with as shown in Figure 2, the present embodiment carries out acoustic construction processing to operator's compartment covering 1, be provided with damping layer 2 in covering 1 inner side, preferably damping layer 2 is by evenly spraying the thick damping slurry of 3mm, or make by the stickup damping of sheet member surface or quality of rubber materials material, can effectively improve covering low-frequency vibration mode, reduce its vibration noise, damping slurry or the damping material of spraying can promote covering 1 noise insulation factor simultaneously, reduce greatly the bite of community noise.
As shown in Figure 3, engineering machinery driving cabin skeleton generally adopts high strength rectangular hollow tubing 3, and the cavity of rectangular hollow tubing 3 can the resonance in chamber produce amplification because of noise equally, thereby becomes a new noise source.Therefore must carry out structure design to rectangle pipe material, the present embodiment all increases shrouding 4 to rectangular hollow tubing 3 ports and carries out soldering, make rectangular hollow tubing 3 cavity inside noises the least possible to operator's compartment internal delivery.
As shown in Figure 4, Cab Mounting System plays vital effect to vibration isolation, self vibration damping.The present embodiment designs Cab Mounting System, and 8 installation sites that suspend, 5,2 cushion blockings 5 of 16 Rubber shock-absorbing pads form one group altogether.Wherein 2 groups of front ends that adopt vertical setting of types to be longitudinally arranged on operator's compartment, another 2 groups of versions that adopt horizontally-arranged to be laterally arranged on operator's compartment tail end, can effectively promote operator's compartment stability is installed, improve operator's compartment uneven road surface is impacted to the damping capacity of the vibration that causes, thereby improvement is vibrated the interior noise producing because of operator's compartment self.
As shown in Figure 5, vibrate for the noise and the operator's compartment self that are penetrated into operator's compartment inside the quadratic noise producing, the present embodiment adopts novel acoustic bag to carry out passive noise elimination.Carry out sound-absorbing by sound-absorbing material layer 6, sound-absorbing material layer 6 parts are pasted on to damping layer 2 surfaces that damping slurry forms, a part is pasted on the inside face of operator's compartment interior trimming parts, thereby forms a sound absorption cavity, and can eliminate gap formation enclosed cavity.The application of novel acoustic bag forms actv. noise reduction barrier, the noise that echoes that can greatly decay in operator's compartment cavity in the cavity of 1, covering at operator's compartment interior trim.
As shown in Fig. 6 and 7, the left and right car door 7 of operator's compartment adopts 2 road Seal Design structures, seals by two seals adhesive tape 8.In operator's compartment, the via hole of wire harness, pipeline all adopts crossover sub 9 to design, and can effectively improve operator's compartment sealing effectiveness, reduces the sound leakage amount of operator's compartment.
As shown in Figure 8, the present embodiment operator's compartment glass for vehicle window adopts double-layered thickened glass 10.Be preferably and adopt double layer glass or double-deck doubling glass, can effectively reduce the sound leakage amount of operator's compartment glass.
Embodiments of the invention are by vibrations and the noise of comprehensive means overall reduction operator's compartment, and technological means translation is good, can promote rapidly in same train product, and successful.
Above specific embodiments of the invention be have been described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and alternative also all among category of the present invention.Therefore, equalization conversion and the amendment done without departing from the spirit and scope of the invention, all should contain within the scope of the invention.
