摘要： An iterative spline function controlled positioning mechanism such as a machine tool. A movable element of the machine tool is driven about a plurality of axes under computer control along a path formed by a plurality of sections. Each of the path sections is represented in parametric form by spline functions. The element is driven through a plurality of intermediate positions approximating positions on the path sections. An iterative algorithm implemented by the computer permits efficient computation of the intermediate positions.

摘要： A method and system for evaluating and tuning axle systems includes at least one test rig on which one or more physical axle systems are mounted. A full vehicle model and a road description are used with the test rig to test and evaluate or tune the axle system as would be conducted on a real test track. The full vehicle model is modified to remove the characteristics of the axle system under test. The remainder of the full vehicle model produces output signals in the form of displacements or loads that are transmitted as inputs to the test rig to apply those signals. The test rig measures output signals in the form of complementary displacements or loads that will become inputs to the vehicle model in place of the removed model of the axle system under test. In this manner, the physical axle system under test is inserted into a real time model of the full vehicle, road and driver.

摘要： A roadway simulator restraint system supports a vehicle at each of its wheels on simulated roadways which comprise endless belts suitably driven to cause wheel rotation. A plurality of passive links are provided for restraining the vehicle in longitudinal, lateral, and yaw degrees of freedom, while permitting free motion in roll and pitch moments, and vertical directions. Additionally, the linkages can provide inputs in aerodynamic force directions to simulate responses to vehicle dynamics during actual operation. The individual roadways that support the wheels can be independently controlled as to speed, and can be turned. Suitable force measurements are made in desired axes to provide for a complete controlled simulation of vehicle operation on an actual roadway.

摘要： A vehicle restraint system for testing vehicles has vehicle restraint linkages which couple to a vehicle mounted on a simulated roadway to provide restraint in selected axes and to permit freedom of movement in other axes in a manner that permits the automobile to react as it would when being driven over an actual roadway. The restraint system is made to combine and limit lateral, longitudinal and yaw motions with a minimum effect on the handling properties in other axes of movement. The restraint system includes selective, active servo positioning in the restrained axes so that the position of the vehicle can be maintained so that the vehicle tires are kept within a load support area of the simulated roadway without substantially affecting the vehicle handling properties. The linkages used are operated through actuators that can also be used as passive restraints, that is, providing a spring force to maintain the vehicle in a desired location. The action of the restraint linkages is through the center of gravity of the vehicle. The three restrained axes are decoupled from each other so that the restraint in each axis does not substantially affect the other axes. Precise simulation of effects on a vehicle of a roadway can thus be obtained.
摘要翻译：用于测试车辆的车辆约束系统具有车辆限制联动装置，其联接到安装在模拟道路上的车辆，以在选定的轴线上提供约束，并允许其他轴线的移动自由度，使得汽车可以像当驾驶在实际的道路上。限制系统被组合和限制横向，纵向和横摆运动，对其他运动轴的操纵性能影响最小。约束系统包括在限制轴中的选择性主动伺服定位，使得可以保持车辆的位置，使得车辆轮胎保持在模拟道路的负载支撑区域内，而不会基本上影响车辆操纵性能。所使用的联动装置通过致动器来操作，该致动器也可以被用作被动约束装置，即提供弹簧力以将车辆保持在期望的位置。限制链接的作用是通过车辆的重心。三个约束轴彼此分离，使得每个轴上的约束基本上不影响其他轴。因此可以获得对道路车辆的影响的精确模拟。

摘要： The flat belt tire tester which permits mounting a wheel and tire to be tested about an axis positioned above a flat belt, and has framework and controls for lowering the tire into contact with the belt under desired loads, using desired adjustments for camber and steering. The belt is powered, and can thus be used for testing the tire under simulated road conditions. The mounting framework and belt mounting construction of the present invention provides substantial rigidity through having the mounting frame geometry properly oriented in relation to the contact surface of the belt and also by providing a stiff frame for the belt mounting drums or pulleys.

摘要： A robot arm and wrist assembly provides a plurality of movable arm sections having a tool supporting wrist at the outer end. The arm has two sections that are pivotally mounted together for movement about horizontal axes, and it can be rotated about a vertical axis. The wrist is all hydraulically operated, and provides movement about three mutually perpendicular axes which intersect at a common point. The overall assembly is light, reliable, and easily programmed for remote control. The robot arms can be controlled by external force, velocity or position sensors in a closed loop system.
