Abstract The advantages of hydraulic mounts over conventional elastomeric mounts for NVH refinement are well known, particularly in the area of engine and suspension mounts. Recently, hydraulic mounts have been successfully employed as body mounts between the frame and cab, principally to control freeway hop in pickup trucks. Due to their ability to provide increased damping at small displacements, hydraulic body mounts also have good potential to reduce smooth road shake. This paper documents the reduction in smooth road shake performance of a full size pickup truck. Hydraulic body mounts tuned to the frequency of the smooth road shake sensitivity area were added to the rearmost cab mount location. Both tire-wheel balance and uniformity were set to the highest production level specification allowed and the effect of hydraulic cab mount was measured experimentally during smooth road driving at medium to high speeds. Hydraulic body mounts were found to be successful in reducing smooth road floor shake by up to 6 dB, thereby considerably refining the vehicle vibration due to first order tire-wheel input forces.

This SAE Standard covers the relative position and direction of motion of controls which influence the movement of the machine and the operating direction only of equipment controls. There is no intention to eliminate or restrict the use of combination controls, automatic controls, or special operating controls. Purpose This document is intended as a guide for designing uniform operator controls for graders. Graders are defined in SAE J/ISO 6165.

This SAE Aerospace Standard (AS) provides requirements for design and installation of aircraft jacking pad adapters and the mating jack socket interface to permit use of standard jacking equipment to be used in civil and military transport aircraft. The adapter defined herein shall be the key interface between the aircraft and the aircraft jack(s).

The AS81824 specification covers environment resistant, permanent crimp type, splices having heat shrinkable insulating sleeve and meltable environmental seals or heatless sealing sleeves. The splices may be used with tin, nickel, and silver plated conductors in applications where the total temperature of the splice application does not exceed 200 °C or as specified in the detail specification.

1.1 Purpose The three parts of SAE J1453 cover material, dimensional, and performance requirements of steel O-ring face seal (ORFS) connectors for tubing and the O-ring face seal interface and nut portion of hose stem assemblies for nominal tube diameters of 6 mm through 38 mm and for nominal hose diameters 6.3 mm through 38 mm. SAE J1453-2 covers the requirements for “metric based” O-ring face seal connectors to metric stud ends along with the associated adapters, bulkhead and union connectors. Metric hex wrenching flats are used throughout this standard. 1.2 Field of Application These connectors are intended for general application and hydraulic systems on industrial equipment and commercial products, where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. These connectors are capable of providing leak proof full flow connections in hydraulic systems operating from 95 kPa vacuum to the working pressures shown in Table 3. Since many factors influence the pressure at which a hydraulic system does or does not perform satisfactorily, these values should not be construed as guaranteed minimums.

This SAE Aerospace Recommended Practice (ARP) sets forth criteria for the installation, inflation, inspection, and maintenance of aircraft tires as well as criteria for the maintenance of the operating environment so as to achieve the purpose stated in 1.1. (Definitions of terms related to aircraft tires are found in 2.2.)

This SAE Recommended Practice describes the basic content requirements, bar-code specifications, and functional test specifications of a vehicle emission configuration (VEC) label. On the vehicle, the VEC label is to be mounted under the hood in a readily accessible location for use of a bar-code scanning device. This document specifies a permanent vehicle emission configuration label that can be automatically identified through a bar-coded format.
