APPLICATION: Heavy duty trucks make use of king pins and bushings as part of their steering pivot points. The king pins are held in place with tapered threaded draw keys. Basically, the king pins have notches on their sides that allow a tapered draw key to be inserted and pounded in place...
APPLICATION: Automotive (heavy truck); Steering & suspension hardware.
DESCRIPTION: Currently, 2, 7/16-20 threaded drawkeys secure a king pin in a heavy truck axle with standard grade 8 lockwashers and nuts.
IDEA: Replace each standard lockwasher and nut combination with a grade 8...
APPLICATION: A kingpin and 2 bushings are used on a semi-truck front axle and spindle combination.
Currently, we supply a kingpin that has a higher hardness than the bushing hardness - thus the bushing wears a certain amount for a certain amount of truck useage. By altering the hardnesses of...
Without being insulting, the author fully realizes that the question posed is about as basic as it gets. I need help in selecting great literature/information on carbon steel round bar for an automotive manufacturing application.
QUESTION:
Would someone please suggest the best website and/or...
I have a question in regards to random vibration profiles. What is the equation that vibration controllers use to calculate the maximum displacement of certain random vibration profiles? Displacement calculations are straight forward for sinusoidal vibration, however, displacement calculations...
To help improve quality, our company will finally set up a Environmental Stress Screen (ESS) for electronic components. I have been involved with durabiltiy for several years. I am now being asked by our manufacturing management to assist the plant in establishing an ESS involving temperature...
I am a 38 year old mechanical engineer with 13 years experinece in the automotive industry. For many reasons, I am considering quiting my salaried day time (1st shift) job to home school my children, including a son with a heart defect - during the day.
Since I am not independently wealthy...
In the automotive durability lab I work in, random vibration is used for durability/life testing and sinusoidal vibration is used for dynamic investigations - resonant frequency and transmissibility(mechanical Q).
My questions invove sinusoidal vibration.
At resonance, it is my understanding...
I work for a global automotive company with several NVH labs worldwide. Although many of these labs are dedicated to testing specific products, the need often arises to take on testing from a sister lab. Lab to lab correlation is required at our company (calibration stuff). However, exact...
SPL data was recently requested and taken on several different steppermotors for an automotive application. That data was collected using an FFT analyzer (RealTime octave Analysis). The data was then provided to the customer, as requested in 1/3 octave bands in EXCEL. The data was first saved...
I am looking for some help regarding calibration of a sound measurement system. A rather basic problem. This is probably a "day 1" problem in any beginner acoustics lab. However, I am able to calibrate the system 3 different ways. And not to my surprise, I end up with 3 rather...
Does any one know if there is a conversion from dB to sones? I have taken a tremendous amount of noise data in dB and dB(A) and the customer is now requesting we supply the data in sones. Any sites? texts? books?
Thanks,
