摘要： PROBLEM TO BE SOLVED: To provide a high noise eliminating effect along a wide frequency zone with a side branch having a short pipe length by branching and connecting the side branch as a pipe body whose tip end is closed, to a main piping in an engine intake piping system or the like in a construction machine, and arranging throttle means in the side branch. SOLUTION: As a large noise source in an engine intake piping system of a construction machine such as a hydraulic shovel, there is noise in a low frequency zone wherein intake pulsation noise generated caused by intermittent combustion of an engine is propagated in an intake piping and it is discharged from an intake taking-in port to outside air. For intake noise countermeasure, a side branch formed in such a way that a close pipe body is branched and connected to a main piping 12 is arranged in the intake piping system, a porous plate (punching metal) 13 provided with many throttle holes 13a is arranged on an inlet part of the side branch so as to constitute a resonance type noise eliminator. A acoustic resistance layer 14 made of steel wool according to necessity is arranged on a back side of the porous plate 13 so as to improve a noise eliminating effect.

摘要： PURPOSE:To simply estimate the vibration characteristics of a damping material molded product with high accuracy by subjecting the estimated frequency response function of the molded product to inverse Fourier transform to calculate impulse response and applying the impulse response to a digital filter. CONSTITUTION:One point of a general steel plate molded product is excited by exciting force F to measure the response transmission mobility response function (a) at an arbitrary point and the modal parameters such as equivalent mass (m), equivalent rigidity (k) or equivalent damping (c) at every vibration mode are calculated. Next, the bending rididity E and loss factor eta of a damping steel plate molded product are calculated from an RKU model and, on the basis of both data, the mobility response function (a) of the damping steel plate molded product is calculated. Further, this estimated function (a) is subjected to inverse Fourier transform to calculate the impulse response to the damping steel plate molded product. The characteristics of the calculated impulse response are applied to an FIR digital filter and the exciting force data of a molded product attaching part at the time of actual operation is inputted to said filter. By this constitution, the vibration at the time of actual operation of the surface of the molded product is falsely outputted from the filter.

Subsequently, the peak frequency to the number of the inherent vibrations of the frequency analysis result of the hitting sound is detected by the processor 6 and average temp. is calculated from predetermined calibration (calibration curve). Thus calculated temp. is displayed on a display board 7 or transmitted to an manipulator as information according to necessity.
