Abstract

In this paper, a PID controller for a special road-rail vehicle is developed. The dynamic model is derived to properly consider the vehicle and track vibrations. This model contains the effects of track elasticity which makes it more reliable and precious compared to traditional models. The vehicle model contains a two dimensional 10 DOF vehicle model, and the track model consists of 40 sleepers. In addition, the effect of the sleeper number on car-body vibration is investigated. The results show that the present vehicle-track coupled model is more efficient in controller design compared to traditional ones. Finally, tuning of controller gains is performed with the aid of a genetic algorithm, in order to achieve a well-organized active suspension.

基于遗传算法车轨耦合模型的某型公路轨道车辆主动悬架设计

本文研制了一种专用路轨车辆的PID控制器。建立了考虑车辆振动和轨道振动的动力学模型。该模型包含了轨道弹性的影响，与传统模型相比更可靠、更有价值。车辆模型包含一个二维10自由度车辆模型，轨道模型由40个轨枕组成。此外，还研究了轨枕数量对车体振动的影响。结果表明，与传统的车辆-轨道耦合模型相比，该模型在控制器设计上具有更高的效率。最后，利用遗传算法对控制器增益进行调整，以实现组织良好的主动悬架。

期刊介绍： The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world. Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email. IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out. Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model. In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay. The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
