Definitions

  • This invention relates to the art of simulation testing.
  • the invention relates to a rig for simulation testing a full exhaust system for an automobile.
  • Durability testing of automotive parts is commonly used to determine the lifetime of the parts. Such testing has been conducted by placing the part to be tested on a "durability automobile” and running that automobile over a test track under prescribed test conditions for a prescribed period of time. That type of testing, however, requires a significant amount of time due to delays in assembling and scheduling the durability automobile and delays caused by downtime attributed to other parts being tested on the same vehicle.
  • Simulation testing was developed to reduce the time required for durability testing and thus to reduce the overall time required for new product development, reducing some new product cycles from as much as nine months to as little as one month.
  • Simulation testing involves placing a part to be tested on a "rig," which is designed to replicate the motion of a durability vehicle to subject the part under test to that motion without the problems incident to actual operation of the durability vehicle. This is often accomplished by placing sensors at critical places on the durability vehicle and recording the relative motions at those locations. Then, the test rig is designed to replicate those motions as exactly as possible.
  • a problem with simulation testing is that of correlation. That is, the results obtained by simulation testing must correlate very well with those obtained by durability vehicle testing for the simulation test to replace the durability vehicle test. Design of a test rig to obtain that correlation has not always been successful.
  • a prior art rig is that known as a MAST (multi-axis simulation table).
  • MAST multi-axis simulation table
  • a known MAST provides motions about six degrees of freedom, namely the three Cartesian directions and roll, pitch and yaw about respective ones of those axes.
  • the motions are provided in prescribed amounts, such as 3.5-7 G's in the translation directions and 0-50 Hz frequency response on all axes.
  • the system is controlled by a computer, and twelve or more input channels from sensors on the equipment being tested are provided.
  • the prior MAST rig suffers from the limitation that it is generally a rigid table (e.g., 60 inches by 84 inches) that subjects the entire part being tested to the same motions. In the field of automotive testing, however, applicant has discovered that such a rig can not adequately replicate the motion of an extended part, such as an exhaust system, on a vehicle. Thus, the typical MAST rig does not provide adequate correlation.
  • MAST'S multiple rigs
  • two MAST rigs are used, with one part of the system being tested being mounted on one and the remainder of the system on the other. While the multiple systems can be connected, such as by mounting one MAST on another, applicant's preferred embodiment provides two independent MAST rigs whereby the motion of the part on one MAST is not dependent on the motion of another MAST.
  • the system to be tested is an exhaust system, which involves an engine with exhaust manifolds, catalytic converters, mufflers, and associated tubing
  • the engine and manifolds are mounted on a first MAST and the remainder of the system on a second, uncoupled MAST. This is accomplished in the preferred embodiment by providing two MAST's longitudinally arranged on a floor.
  • each of the MAST's can be programmed separately, the motions applied to the engine and the mufflers can differ and can, therefore, come much closer to replicating the actual motion of the various parts of the durability vehicle.
  • FIG. 1 is a plan view of a dual MAST rig in accordance with the invention.
  • Figure 2 is a side view of the rig shown in figure 1.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the figures, a multiple-MAST full exhaust system simulation rig in accordance with the invention comprises a first MAST rig 2 and a second MAST rig 4 arranged adjacent each other and mounted on a common floor, such as the concrete floor of a test facility.
  • Each of the MAST rigs 2 and 4 is preferably capable of providing motions about six degrees of freedom. Because the rigs are not coupled, they may be controlled separately to accommodate different motions of the different parts of a vehicle for which the exhaust system is designed.
  • Each MAST includes a table 6 that is mounted for motion about six degrees of freedom.
  • the tables are generally rigid and are connected to a plurality of computer controlled, hydraulic actuators to provide the required motion.
  • Three of the actuators 8 for each table are mounted for horizontal motion, with two parallel and one perpendicular to the others.
  • At least three actuators 10 are provided beneath each of the tables for generating vertical, and pitch and roll motions.
  • an engine 12 is mounted on a first of the MAST rigs and the tail pipe hangers 14 are mounted to a second of the MAST rigs.
  • the MAST rigs shown are those manufactured by MTS Systems of Loveland, OH, but the rigs may be of other types.
  • the MAST rigs shown are generally capable of providing motions in the range of 0 to 50 Hz.
  • one of the MAST rigs is replaced with a system that provides motions at higher frequencies, such as that sold under the trademark CUBE, e.g., for mounting the engine.

Abstract

L'invention concerne un système d'essai de simulation destiné à tester un système ou un composant automobile, tel que le système d'échappement (14), qui comprend une première et une seconde table de simulation multiaxiale (MAST). Une partie du système d'échappement est supporté par une des tables, une autre partie étant supportée par l'autre table. Chaque table comporte des actionneurs hydrauliques (8) capables d'exercer un mouvement sur les tables dans plusieurs directions. Les tables sont indépendantes l'une de l'autre de façon que le mouvement exercé sur une table puisse être distinct et commandé séparément du mouvement exercé sur l'autre table. Disposer les tables de manière à permettre une variation des mouvements entre les deux tables permet de développer un essai de simulation plus réaliste du système ou du composant à l'essai.
