The invention discloses an interval optimum design method for a vehicle powertrain mounting system. The technical scheme is as follows: a mounting decoupling model is established by an interval analysis theory; the technical parameters of the powertrain mounting system are determined by taking six-degrees-of-freedom decoupling of the mounting system as an objective function, taking mounting stiffness as an optimum variable, and taking a six-degrees-of-freedom vibration frequency as a constraint; the six-degrees-of-freedom decoupling of the mounting system is carried out by using PSO (Particle Swarm Optimization). The method mainly comprises the following specific steps of: A. mounting decoupling calculation model; B. mounting decoupling optimization model based on an interval analysis theory; C. interval optimization model based on particle swarm optimization and optimization calculation. After optimization, frequencies of a powertrain in all directions are controlled within design requirements ...

The invention discloses a hydraulic clamp used for an end face hole of a horizontal type center drill bent axle. The hydraulic clamp is mounted on a horizontal type machining center platform. The clamp comprises a clamping mechanism and a connecting rod positioning mechanism. The clamping mechanism utilizes a V-shaped supporting block to support a main shaft neck of a bent axle and can be used for adjusting the position according to the size of the bent axle; the connecting rod positioning mechanism adopts a hydraulic loop composed of a hydraulic pump, an electromagnetic directional valve and an oil returning tank to realize a connecting rod clamping and positioning function. The whole clamp has a reasonable structure and is convenient to assemble, and is applicable to the machining of various bent axles; the labor intensity of workers can be alleviated and the machining efficiency is greatly improved.
