The invention discloses a design method for restraining vehicle jittering, electronic equipment and a storage medium, and relates to the technical field of vehicle noise control. The design method comprises the steps that a preset excitation frequency range corresponding to the jittering state of a vehicle is obtained by establishing a rigid body mode of a power assembly, the inherent frequency in the target direction is compared with a preset excitation frequency range, if the inherent frequency in the target direction is within the preset excitation frequency range, characteristic parameters of the suspension system are adjusted, and the rigid body mode of the power assembly is updated; and if the inherent frequency in the target direction is located outside the preset excitation frequency range and the overall inherent frequency of the rigid body mode does not exceed the ignition excitation frequency preset value of the engine, characteristic parameters of the suspension system are output. The risk of intermittent shaking of the vehicle is reduced, and the comfort of the whole vehicle is improved.
本申请公开了一种抑制车辆抖动的设计方法、电子设备和存储介质,涉及车辆噪声控制技术领域,其中,设计方法包括通过建立动力总成的刚体模态,获取车辆的抖动状态对应的预设激励频率范围,对目标方向的固有频率和预设激励频率范围进行比较,若目标方向的固有频率位于预设激励频率范围内,则调节悬置系统的特征参数,更新动力总成的刚体模态;若目标方向的固有频率位于预设激励频率范围外,且刚体模态的整体固有频率不超过发动机的点火激励频率预设值,则输出悬置系统的特征参数。本申请降低了车辆间歇抖动的风险,提高了整车舒适性。
