A Comparison of Decomposition Constructs for Supporting Modularity in Simulink

2020-01-129004/14/2020

The Model-Based Development (MBD) paradigm is widely used for embedded controls development, with MathWorks’ Simulink modelling environment being extensively used in the automotive industry. As production-scale Simulink models are typically large and complex, there exists a need to decompose them properly in order to facilitate their maintainability, understandability, and evolution. MathWorks recommends the use of three constructs for model “componentization” or decomposition: the Subsystem, Library, and Model Reference. However, a recently added construct, the Simulink Function, can also be used for this purpose, while also supporting information hiding due to the construct’s ability to be scoped and encapsulate data. This paper provides an in-depth comparison of these Simulink constructs to fully understand the differences in their reusability, sharing of program state, encapsulation, and code generation, with the goal of facilitating model evolution.

Recommended Practice for Optimizing Automobile Damageability and Repairability

J1555_201910 (Current)10/24/2019

This SAE Recommended Practice applies to all portions of the vehicle, but design efforts should focus on components and systems with the highest contribution to the overall average repair cost (see 3.7). The costs to be minimized include not only insurance premiums, but also out-of-pocket costs incurred by the owner. Damageability, repairability, serviceability and diagnostics are inter-related. Some repairability, serviceability and diagnostics operations may be required for collision or comprehensive loss-related causes only. Some operations may be for non-collision-related causes only (warranty, scheduled maintenance, non-scheduled maintenance, etc.). Some may be required for both causes. The scope of this document deals with only those operations that involve collision and comprehensive insurance loss repairs.

Bolt and Capscrew Sizes for Use in Construction and Industrial Machinery

J370_200604 (Current)04/17/2006

This SAE Recommended Practice covers the use of preferred bolt and capscrew sizes, wherever applicable, on construction and industrial machinery to ease serviceability. Designers, in their efforts to determine the proper fastener for heavy equipment, sometimes overlook the practical aspects of serviceability. When a particular component requires frequent service, it is much faster and easier for the serviceman to work with common size, easily distinguished bolts and capscrews which require a minimum of tools. Section 4 lists eight diameters of recommended bolts and capscrews, some of which can be found in any hardware store, require only standard tools, are easy to distinguish, and at the same time cover proof loads from 1043 kg (2300 lb) on up at convenient intervals. While some applications may require other sizes and/or fine threaded fasteners for greater camping forces and/or area restrictions, the convenience of UNC threads in the sizes indicated is preferred wherever possible.

A Primer of Aircraft Multiplexing

AIR1207 (Current)08/01/1991

Today's sophisticated aircraft are required to effectively perform a variety of missions. With the advent of micro-miniaturization in electronics and advanced digital computers, a new generation of avionics equipment and systems can be utilized to increase the capabilities of the aircraft. As the quantity and variety of equipment and functions increases, the problems of inter-connecting these equipments with wires presents a constraint on size, weight, signal conditioning, reliability, maintainability and electromagnetic control. Conventional wiring has resulted in large bundles of wires and many connectors which adds excessive weight and reduces the space available for the pilot and other vital elements. This limitation can be relieved significantly by the application of well proven multiplexing techniques.

Risk Analysis in Maintainable Designs

79028402/01/1979

In the past few years, there has been an increasing utilization of risk analyses of reliability and safety considerations in the design and management decision processes. Management decisions, however, are contingent on matters other than the strictly technical. A primary business objective is to gain the customers' acceptance by satisfying the criteria of product availability. This can be attained by providing highly reliable and/or easily maintainable products. These can be two different design philosophical approaches. In the design philosophy where a highly maintainable design is the best alternative, risk analysis becomes an important tool in assessing the risk of “down time” as well as the risk associated with maintenance actions. This paper will discuss the twin aspects of availability and maintainability and their impact on management decisions. A practical example is given.

Improving Serviceability

78043102/01/1978

Rising costs have increased the need for simplifying service. The response at Cummins Engine Company has been a program to improve the serviceability of engines, plus an effort to help equipment manufacturers make engines more serviceable in their installations. The program is a cooperative effort among several areas. Design criteria for improved engine serviceability are discussed. Key maintenance and repair operations are used as the basis for measuring and comparing the serviceability of engines. The method presented is flexible enough to allow various trade-offs to be made during the design stage. Guidelines for improved installation serviceability are outlined. The guidelines establish time limits for daily checks and routine maintenance, plus targets for service repairs. These are based on the times to perform the respective operations on free standing engines with allowances for installation considerations.

A Fluidically Controlled Aircraft Fuel Transfer System

70078602/01/1970

Traditional methods of electrical sensing and control in jet aircraft fuel transfer systems have proven expensive, hard to maintain, and sometimes unreliable. This paper presents a new concept in fuel sensing and control using fluidics. The objective was to construct a general three-tank model system for exploring concept feasibility. Although a single medium (fuel) approach was sought, the interim model used a pneumatic logic and sensing system for fuel control. The laboratory model effectively demonstrated fuel level control, diversion of fuel transfer at the command of an automatic logic system, and pilot override. A trade study showed gains in reliability and maintainability over the current method of aircraft fuel transfer control. Advantages were: no dependence on electric or hydraulic power, ease of maintenance, and fail-safe operation.
