General Overview

IPC TA-723 SECTION 7 质量评价

on through military avionics and automotive (under the hood). Article 7.10 provides the design requirements for each of the nine product use categories; and provides general worst-case use environments, years, of service, acceptable failure risk, suggested accelerated testing requirements. Identification of an appropriate use environments is a critical design requirement because it establishes the base line to ensure the product the product's reliability and other quality requirements.

Quality Assessment

IPC TM-650 4.0 第4节目录

Because of a need for technical information, and to develop standards in the field of printed wiring, the IPC was formed in 1957. It stands today as an organization dedicated to the technological advancement of the printed board industry.

AGMA 90FTM4-1990 磨损的不同类型.如何分类？

In the first part, this document describes all the types and aspects of wear which can occur on the gear teeth in operation, with causes and explanations concerning their appearance. For each type of wear, the possible evolution and the limits which should not be overpassed to avoid a failure or severe damage to the teeth, thus reducing the life of the gear, are clearly specified. Aspects of wear types which can be considered as normal, medium or progressive are also described and solutions are presented as a guide for wear stabilizing. This document is illustrated with numerous pictures of all types of wear. The other types of gear failures such as surface fatigue, corrosion, plastic flow and breakage are not included in this paper which is only dealing with wear.

Different Types of Wear- How to Classify?

AGMA 90FTM10-1990 滚柱试验中带与不带氮化钛涂层的失效机理

To clarify the effect of Titanium Nitride (TIN) coatings on the failure resistance and frictional characteristic and compare this effect with that produced by the heat treated coatings, two roller tests have been made and the stress resulting from the combination of the Hertzian stress field and frictional force field on and below zhe contacting surface as well as the flash temperature rise were calculated. The failure resistance of the TiN-coated roller pair was greater than that of the heat treated roller pair. The mechanism of failure resistance can be explained by the shearing stress (Hertzian stress + frictional force) acting on the contact surface. This stress modifies the structure in the vicinity below the TiN layer which is then sheared in the wear track direction.

AGMA 90FTM11-1990 多重迭代.大量反复试验和误差

"Trial-and-error" was once a dirty word. Now, with computers, it has become the most valuable tool in engineering calculation. The procedure described in this paper permits any number of input variables (say A,B,C) to be systematically varied until an equal number of results (say X,Y,Z) are zero, regardless of the complexity of the equations relating A,B,C to X,Y,Z. It has been used successfully by the writer for up to seven variables. This paper is not concerned with the structure of the computer program representing this procedure, but rather with the kinds of engineering problems that can use it, and how it can be used as a subroutine in engineering programs. Two actual gear applications will be described. There will also be a discussion of problems of non-convergence that may arise, and the necessity for good starting values. The program is written in elementary BASIC, so that it can be read and modified by the user if desired.

Multiple Iteration- Respectable Trial-and-Error

AGMA 90FTM12-1990 控制变速驱动器的新系统设计

Processes in chemical industries and power plant stations require to a certain extent variable speed drives of high power capacity. In contrast to controlled hydrodynamic or friction clutches a new system of hydrostatic controlled superimposed planetary gears was developed. Design and calculations as well as efficiency comparisons to other systems will be described. Practical experiences in the drive of large boiler feed pumps will be explained which prove the reliability of these drives.

AGMA 90FTM5-1990 抛光磨损

Polishing wear has been known to occur on piston rings, cylinder bores, valve lifters, hydraulic components, rolling-element bearings and gear teeth. The bright, polish surfaces may look good, but polishing wear is detrimental because it is a high wear phenomenon which reduces the geometric accuracy of the components. A case history is presented of a gearbox which suffered extensive polishing wear of the gear teeth and rolling-element bearings. The results of research into the basic mechanism of polishing wear, and laboratory analyses of materials and lubricants are presented. Polishing wear is shown to be due to fine-scale abrasion. It is promoted by a combination of a fine abrasive and a gear oil with chemically-active additives.

POLISHING WEAR

AGMA 90FTMS1-1990 传输的运动学分析.基于有限元方法

In order to evaluate the kinematic properties of a design of a transmission in its early stages, a computer program has been developed. By means of geometric reasoning a finite element model is deduced from the conceptual design which has been built using an experimental 3D object editor. Since the interrelations between the objects are not specified by the designer they are found by the computer by supplying a set of rules. The following kinematic analysis uses a mixed Euler/Lagrange description and detects mechanisms (possible infinitesimal displacements of the nodal points without causing strain in the elements) in the transmission. The mechanisms found are visualized by the object editor by means of alternating images of the design on the screen which gives a real idea of motion. A well-founded decision can be made whether the conceptual model has to be changed, rejected, or can be accepted. The method of analysis used gives a good start for a static and dynamic analysis.
