摘要 为了深入理解发动机前端附件带传动系统功率损失及其影响因素,通过多体动力学仿真计算某附件传动系统的功率损失。通过试验测定了某型皮带的力学特性参数,据此在Adams软件中建立了系统仿真模型。结合模型阐述了计算附件传动系统功率损失的基本方法与过程。通过仿真计算得到了系统功率损失,研究了预张力、负载、转速和加速度等因素对功率损失的影响。结果表明: 功率损失随预张力、负载、转速单调递增,随加速度的变化较小。推算了该系统在一种典型工况下因功率损失造成的油耗。通过开展空载台架试验对比证实了计算模型与方法的正确性。

Abstract:The effects of a power loss to the engine front end accessory belt drive systems were studied using a multi-body dynamic simulation. The mechanical parameters of the belt were found in tests with the system dynamic model then built in the commercial software Adams. The effects of the system power loss were found through a series of simulations for the key design parameters, such as the belt pre-tension, accessory loads, rotating speed belt and pulley acceleration, and fuel consumption, for typical vehicle driving cycles. The results show that the power loss increases monotonically with pre-tension, load and rotating speed and changes little with acceleration. The fuel consumption agrees well with bench tests of a drive system without any accessory loads.
