J1199_198309
This SAE Standard covers the mechanical and material requirements for eight property classes of steel, externally threaded metric fasteners in sizes M1.6 through M36, inclusive, and suitable for use in automotive and related applications. Products included are bolts, screws, studs, U-bolts, preassembled screw and washer assemblies (sems), and products manufactured the same as sems except without washer. Products not covered are tapping screws, thread-rolling screws, and self-drilling screws. Mechanical and material requirements for these products are covered in other SAE documents. The term stud as referred to herein, applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. For specification purposes, this document treats U-bolts as studs.

An analytical solution is given for W, the dimensionless load-capacity of a plane, finite, rectangular-pad, slider bearing. This solution is suitable for small computers so that students of tribology can carry out calculations on a realistic bearing without having to use a large computer which may not be readily available. The solution described is superior to that obtained by the use of standard numerical methods on Reynolds equation because it is obtained more rapidly, it needs less computer memory storage space and can be carried out in single precision.

The main objective of the design has been to combine the suspension elements of a live axle in such a way that low frequency (50 - 200 Hz) engine torque fluctuations will be adequately insulated from the body and in this way diminish any tendency to body boom even when driving at low speed with a 4 cylinder car. The goal should be met without infringing upon other desirable characteristics of the rear axle suspension. The importance of wind-up compliance, and properly positioned attachment points on the rear axle housing is stressed. Results from sound and vibration measurement and computation are given.

The suspension system of the Nissan Stanza was specifically designed for use on a front-wheel-drive car. It was developed with the idea that the new suspension should be compact and light, and afford a comfortable ride as well as good stability and controllability. Furthermore, it should have excellent noise and vibration characteristics. To achieve these objectives we adapted a strut suspension for both the front and rear, and careful consideration was given to the fundamental specifications. In addition, some new ideas were applied for the layout of the suspension.

We discuss the problems of comfort and handling of european vehicles using a typical example: the RENAULT 9. Many problems related to weight, size, unibody construction and, four cylinders engines… are given. Some details about the means used to solve them are given and solutions for a RENAULT 9 are analysed. Of corse the vehicle represents a compromise adapted to european market vehicle which is rather different from the U.S. Market, a factor considered in the design of the RENAULT-AMC Alliance.

This ‘paper’ discusses current power steering characteristics and considers why and how the characteristics should change for different driving conditions. It then compares the different ways in which this can be done and considers the advantages and disadvantages of each, including some of the safety aspects. It is mainly, but not exclusively, concerned with motor cars and is basically confined to the modern hydraulic power steering rotary valve which uses torsion bar springing. Most of the illustrations relate to rack and pinion steering but, in a general sense, all that is said can be applied to other types of steering gear.

Unlike conventional tilt-wheel devices, the newly developed ones have a “memory mechanism” which allows steering wheels to return to pre-set tilt-angle positions selected by individual drivers using only a single lever. This paper describes the design of such devices and outlines the engineering and test results regarding certain problems, such as the vibration of the systems and influences on the original energy-absorbing characteristics caused by weight addition and increased complexity of the wheel columns.

The most effective way to improve the driver's road feel at high speeds is to increase the stiffness between the steering wheel and the vehicle's wheels at times when only a small amount of steering effort is required. Though rack and pinion steering systems have good features in this respect compared with recirculating ball steering systems, which have been commonly used in Japan and the U.S.A., we are studying ways to improve the stiffness of rack and pinion steering systems by analyzing the effects of each parameter on stiffness. The effect of the stiffness of rack and pinion steering gears on overall automotive steering systems is analyzed here based on actual vehicle tests, which naturally include the stiffness of the vehicle's wheels on the road.

Hitachi has recently developed a hot-wire air flow meter which uses a temperature-sensitive resistor of an extremely thin platinum wire wound around a ceramic bobbin and coated with glass. This temperature-sensitive resistor, or a hot wire, is located in a bypass of the intake air passage of an engine and responds exactly for the effective control of engine operation. The flow meter of this construction is sturdy enough to withstand impacts of backfires and vibration and reduces variation in engine output characteristic likely to be caused by dust and dirt present in the intake air. Furthermore, this device requires no cleaning or other maintenance.

Numerous text books are available on BASIC programming, however, many practicing engineers do not have the time to read lengthy texts. The object of this paper is to summarize the most important aspects of elementary BASIC programming. A working knowledge of the material in this paper will provide the ability to use computers in solving most of the common engineering problems.
