Abstract

This paper presents experimental result of mode shape effect in automobile braking system. Experimental of modal testing and analysis is done by given an impact by hammer from point 1 to point 24 of the disk brake where the accelerometer is positioned. The average data is recorded and a three dimensional graph is plotted. From the recorded vibration, the modal parameters of this disk brake are determined from the mode shape developed using numerical and experimental approach. The result shows three natural frequencies are identified at 1100Hz, 2350Hz and 2600Hz. The first mode shape shows the direction of the bending is the same where it was a top bending. From initial condition, when the shape was moving at up and down, the contour color is slightly changed from blue to yellow and red. The second mode shape shows the bending moves up and down following the z-axis. When the point is far from the initial condition, the contour is changed from blue to yellow and frequently was red. The deformation of disk brake at second natural frequency is slightly increased when the point goes far from initial condition. For a third mode shape at positive and negative of z-axis, the color of shape is slightly changed when the area is bending condition. It means, the deformation of the disk brake is changed as well follow by the magnitude of bending.
