Among the various elements affecting a customer’s evaluation of automobile quality, buzz, squeak, and rattle (BSR) are considered to be major factors. We propose an integrated experimental method that can be used to reduce BSR in an instrument panel module in a vehicle cabin, especially during the early design stage of vehicle development. We devised a vibration triggering system consisting of ...

The leakage of tricresyl phosphate-containing engine lubricants into aircraft cabin air, either from worn or defective engine seals or under normal operating conditions, is a serious concern for both the health and safety of the cabin occupants, since the oil contains one to five percent tricresyl phosphate (TCP) esters, known neurotoxins. The exposure of pilots is a particular concern since th...

Accurate prediction of particle deposition in airliner cabins is important for estimating the exposure risk of passengers to infectious diseases. This study developed a Detached-Eddy Simulation (DES) model with a modified Lagrangian method. The computer model was validated with experimental data for particle deposition in a cavity with natural convection and with air velocity, air temperature, ...

Air path model of cabin for cooling module simulation for vehicle has been constructed according to the test, and the simulation results were compared with the test data to verify the authenticity of the module. This simulation model provides an effective platform for vehicle thermal management analysis. The module is used to simulate the different intake grills and to find how different grills...

or the automotive industry, acoustic comfort is of increasing importance. Customer expectations and strong competition in market play an important role to accelerate vehicle development activities. Although primary function HVAC (Heating ventilation Air-conditioning) thermal occupant during ride; also when it comes customer satisfaction resulting overall experience vehicle. Hence, prediction ca...

A method to intended for measurement of the insertion loss of an acoustic treatment applied to an aircraft fuselage in-situ is documented in this paper. Using this method, the performance of a treatment applied to a limited portion of an aircraft fuselage can be assessed even though the untreated fuselage also radiates into the cabin, corrupting the intensity measurement. This corrupting noise ...

In a previous study we found large systematic errors (up to 40 degrees) when subjects adjusted the orientation of a horizontal test bar until it appeared parallel to a horizontal reference bar, both bars rotating about their vertical axes. The deviations increased linearly with the separation angle but vanished when the orientation of the reference bar was either parallel or perpendicular to th...

High comfort for the driver in working vehicles is an important feature as well as a demand from the drivers. Low noise level is an essential factor for the manufacturer to maintain a high standard and comfort of vehicles. In many cases the noise inside the cabin can be related to the engine orders. Hydraulic pumps and fans are also related to the engine but not necessarily integers of the engi...

Title: BEYOND RACIAL STEREOTYPES: SUBVERSIVE SUBTEXTS IN CABIN IN THE SKY Kate Marie Weber, M.A., 2008 Directed by: Dr. Richard King, Associate Professor of Musicology The 1943 film Cabin in the Sky holds an important place in cinematic history as one of the first “all-Negro” pictures produced by a major Hollywood studio. The movie musical reflects a transitional period in American racial polit...

When a panel is excited, either structurally or acoustically, sound is radiated from the panel. Previous research by the author has shown that tuned acoustic tube resonators can be used to reduce the radiated sound. A one-dimensional analytical model model was validated by experiments in an impedance tube and good agreement was found between model and measurements. In this paper, the model is e...
