On the other hand, in order to improve the quietness in the vehicle interior, which is an important factor in the performance of vehicles, conventional methods have been used to reduce the vibrations of the panels by pasting damping materials on the panel surfaces. However, although the above method is direct and effective, it has problems such as an increase in the weight of the panel and a complicated work process. (Objective of the Invention) In view of the above problems, the present invention has been developed The aim is to add vibration damping effects to conventional reinforcement meshes, eliminating the need for damping materials for vibration damping.

Now, in this experiment, in order to investigate the vibration reduction effect of the above two types of test pieces, that is, the Ill 7111 vibration effect, a steel plate of the same size as the above test piece was used, and the test piece (1) was placed on this 44 plate. They were installed in two ways: in close contact with each other (via rubber spacers with a thickness of 21 and 5 strips).

The real method is to vibrate the lower steel plate and set it above it:
As shown in Figure 1, the vibration of the test piece is determined by 811, and as shown in Fig. A spacer is installed between the vibration damping steel plates. Condition 2: A spacer is installed between the damping steel plates. Four types of experiments were conducted as described above.

The horizontal axis represents frequency (unit: KHz). Further, symbols A-D in the figure correspond to experimental conditions A-D in FIG. 2. Figure 2 shows the damping copper plate and PLA plate 1 Figure 3 shows! It shows the allocation effect of a state with fJi and a state with a hollow part in the combination of @temporary comrades. According to this, in a combination of steel plates, the distribution effect is greater when the steel plates are combined in one tithe, and in the jf1 combination of steel plates and damping steel plates, an extremely large distribution effect is achieved by providing a hollow part. I found out that it was Saroko. Figure 4 shows the installation method with the same hollow part.
This shows the 1 series vibration effect due to the combination of the lA slope and the steel plate-damping steel plate, and it can be seen that as the frequency increases, the latter's ;l;:1 vibration effect becomes extremely large.

If you use a damping steel plate that is r This is an example in which the present invention is applied to a Datsun 7 Euro Apparel, which is one of the body panels of an automobile. This panel separates the second/engine compartment from the passenger compartment, and if it is joined with the reinforcement made of distributed steel plate according to the present invention, it will effectively reduce the noise that enters the first vehicle (inside the vehicle) during acceleration, for example. It is also possible to suppress the vibration of the wires attached to this panel, so it is expected that their reliability will be the same.
