Automotive applications engine mounts

FE simulations of the stress-strain properties of fiUer-reinforced elastomers are an important tool for predicting the service live performance of mbber goods. Typical examples are the evaluation of rolling resistance of tires due to hysteresis energy losses, mainly in the tire tread or the adjustment of engine mounts in automotive applications. 

The steel industry in the United States has not yet installed the equipment necessary to fabricate the new large diameter (over 42" O.D.) line pipe being specified for many major line pipe projects. On the other hand, Canada, Japan, West Germany and Italy are well equipped to produce the pipe and are expected to be the major recipients of line pipe orders. As a result, increasing demand for vanadium in the United States is expected to be modest and, in the absence of other major developments, such as automotive HSLA use, will remain at 3% per year through 1980. The potential application of HSLA steels to automobile bumpers, frames, engine mounts, etc., could increase United States vanadium consumption by 10-15% or 1 to 1.5 million pounds per year. However, competition from other materials precludes an accurate appraisal at this time.

The same (or a very similar) silane process can be used for many other automotive and non-automotive bonding applications, such as engine mounts. 

Some of the key properties of PAREL elastomer vulcanizates are summarized in Table I. They have excellent low teiqierature properties excellent dynamic properties, which are much like those of natural rubber good ozone resistance and good heataging resistance. This interesting combination of properties is leading to substantial specialty markets in such applications as automotive engine mounts. Vulcanization and stabilization studies on PAREL elastomer, as well as additional specific properties of PAREL elastomer, are reported in this book by Boss. 

Most butyl rubber is used in the tire industry. Isobutylene-based rubbers are used in underhood hose for the polymer s low permeability and temperature resistance, and high damping, resihent butyl rubbers are used for noise and vibration attenuation applications such as automotive mounts for the engine and vehicle. Chloro- and brominated butyl rubber formulations are used in automotive hose applications where contact with fuel or air conditioning fluids occurs.
