The invention belongs to the technical field of vibration noise testing, and particularly relates to a mechanical hydraulic type mixed supporting device which comprises a base, a mechanical sleeve is arranged on the base, and a rotary adjusting rod is arranged on the mechanical sleeve; the hydraulic supporting structure is arranged on the base, the hydraulic supporting structure comprises a hydraulic cylinder, a piston and an oil pump, the piston is arranged in the hydraulic cylinder, the oil pump is connected with the hydraulic cylinder, and the oil pump is used for providing pressure oil and driving the piston to do reciprocating motion in the axial direction of the hydraulic cylinder. The mechanical and hydraulic hybrid supporting device combines the advantages of two different supporting modes, namely a mechanical supporting mode and a hydraulic supporting mode, can stably provide supporting force for a long time, and avoids the possible pressure relief problem of a traditional hydraulic supporting device.
本发明属于振动噪声测试技术领域,具体涉及一种机械液压式混合支撑装置,包括:底座,所述底座上设有机械套筒,且在所述机械套筒上设置旋转调节杆;液压支撑结构,设于所述底座上,所述液压支撑结构包括液压缸和活塞、以及油泵,所述活塞设于所述液压缸内,且所述油泵与液压缸连接,所述油泵用于提供压力油,并驱动所述活塞沿所述液压缸的轴向做往复运动。该机械液压式混合支撑装置结合了机械和液压两种不同支撑方式各自优点,可以在长时间内稳定地提供支撑力,避免了传统液压支撑装置可能出现的泄压问题。
