摘要： The invention provides in one aspect a suspension testing apparatus which uses air bearings (96) which have a low coefficient of friction. The invention provides in a second aspect suspension testing apparatus which ensures accurate measurement of suspension characteristics since the apparatus applies forces directly below the centre of the vehicle wheel hub (12) (or forwardly or rearwardly therefrom at a distance equivalent to the pneumatic trail of the tyre in the wheel (12)) to ensure that the point of application of a force remains constant despite rotation of the support means (10) for the wheel (12) during deflection of the vehicle wheel (12). The invention in a third aspect provides new sensor means (22) for measuring the vehicle wheel deflection which uses a minimum number of transducers (162, 163, 164) to accurately monitor tyre and wheel deflection during use. The invention provides in a fourth aspect testing apparatus which uses mechanical actuators (15, 23) rather than hydraulic actuators to cause motion of the support means, which give an indication of the displacement of the support means. In a sixth aspect the invention provides a method of testing a vehicle suspension using the apparatus of the invention.
摘要翻译：本发明在一个方面提供一种使用具有低摩擦系数的空气轴承（96）的悬架测试装置。本发明提供了一种第二方面的悬架测试装置，其确保对悬架特性的精确测量，因为该装置将力直接施加在车辆轮毂（12）的中心下方（或者向前或向后的距离相当于轮胎（12）），以确保尽管在车轮（12）的偏转期间用于车轮（12）的支撑装置（10）的旋转，力的施加点保持恒定。本发明在第三方面提供了用于测量车轮偏转的新的传感器装置（22），其使用最少数量的换能器（162,163,164）在使用期间精确地监测轮胎和车轮的偏转。本发明在第四方面提供了使用机械致动器（15,23）而不是液压致动器来引起支撑装置的运动的测试装置，其给出了支撑装置的位移的指示。在第六方面，本发明提供使用本发明的装置测试车辆悬架的方法。

摘要： An adaptive control system reducing undesired signals comprises a processor (36) which provides secondary signals for sources (37) for interference with the undesired signals. Sensors (42) measure the residual vibration which is indicative of the interference between the undesired and secondary signals. The processor (36) uses the residual signal to adjust the secondary signals to reduce the residual signals. Noise generation means (48) is provided to add a low level noise signal to the secondary signal and to provide a low level noise signal to the processor (36). The processor (36) is adapted to transform the low level noise signal and the residual signal from sensors (42) to provide the amplitude and phase of spectral components of the signals. The processor (36) modifies the secondary signals using these spectral components to obtain better reduction of the undesired signals.

摘要： The present invention relates to actuator (11) comprising a piston (16) with a cylinder (17). The piston (16) divides the cylinder (17) with at least two chambers. An orifice (53) is provided in an end surface of the cylinder (17). The said end surface and the nearest piston surface are shaped so that as the piston (16) approaches the said end surface the flow of fluid from between the said end surface and the said piston surface to the orifice is restricted. Preferably the end surface and the piston (16) define between them two subchambers (54, 57) and an interconnecting passage (58) for the last portion of motion of the piston (16) towards the end surface. The passage (58) decreases in size as the piston (16) approaches the end surface and increasingly restricts flow of fluid between the two subchambers (57, 54).

摘要： An adaptive control system is provided for controlling a plant subject to repetitive phenomena having at least one frequency component. The system comprises a complex reference generator for generating a complex reference signal having in-phase and quadrature components substantially at a frequency of one of the frequency components. A first heterodyning arrangement is provided to heterodyne the complex reference signal with the complex control coefficients to generate at least one control signal having an in-phase component for use in the control of the plant to generate at least one desired output signal. The frequency components in the output signal are correlated with the complex reference signal to generate complex update coefficients and a second heterodyning arrangement heterodynes the output signal with a signal derived from the complex reference signal to generate the complex update coefficients which comprise sum and difference components. An integrator integrates the complex update coefficients comprising the sum and difference components to generate the complex control coefficients.

摘要： An adaptive control system for controlling a plant (C) generates an input signal for control of the plant. An adaptive response filter (W) which has a plurality of time domain filter coefficients which are operative to filter the input signal to provide a control signal for the plant (C) so that the plant generates the required output signal. A model filter ( C ) which also has a plurality of time domain filter coefficients models the response of the plant and filters the output signal using the filter coefficients in relative time reverse order to provide at least one filtered output signal. A delay (Z) delays the input signal for a predetermined time period. The adaptive response filter receives the delayed input signal and collates this with a respective filtered output signal and adjusts its filter coefficients using the outcome of the collation to adjust the control signal for the plant such that the output signal of the plant converges towards a required level.

摘要： An adaptive control system for reducing undesired signals comprises sensors (31) to provide signals indicative of the undesired signals, and a processor (36) which processes the first signal to provide a secondary signal for output to sources (37) to interfere with the undesired signals. Sensors (42) are provided to detect the residual signals which are indicative of the interference between the undesired and secondary signals. Within the processor the signals indicative of the undesired signals and the residual signals are transformed into the frequency domain and collated. The outcome of the collation is inverse transformed and the processor adjusts the secondary signal using this inverse transform to reduce the residual signal from the sensors (42).
