Rotational inertial simulating device capable of stepless inertia adjustment and inertia adjusting method of device

Abstract

The invention discloses a rotational inertial simulating device capable of stepless inertia adjustment and an inertia adjusting method of the device. The device is composed of a mechanical support part, an inertial simulation part and an adjustment control part. In the inertial simulation part, a flange is coaxially connected with a central rotating shaft of the mechanical support part, a basal disc and a control disc are coaxially connected to the two ends of the flange respectively, a sector-shaped inertia simulated mass block is coaxially slidingly mounted in a linear radial sliding hole inthe basal disc and a spiral radial sliding hole in the control disc by means of a clamping bolt, and fixed by a clamping nut, the adjustment control part is mounted between the basal disc and the control disc, and the adjustment control part drives the control disc to rotate relative to the basal disc. According to the inertia adjustment method, the adjustment control part drives the control discto rotate relative to the basal disc, the inertia simulated mass block is expanded or contracted relative to the axis, and the inertia is adjusted. The magnitude of rotational inertia can be adjustedsteplessly according to concrete test requirements, and inertia adjustment is convenient and feasible.

Description

technical field [0001] The invention belongs to the technical field of performance bench testing of automobiles and powertrain parts thereof, and in particular relates to a moment of inertia simulation device capable of steplessly adjusting inertia and an inertia adjustment method thereof. Background technique [0002] In the development process of automobiles and their powertrain components, a large number of experiments are usually required to verify the simulation results and the design performance of components. Compared with the real vehicle experiment with long test period and high test cost, bench test has become an important test technical means in the process of automobile development due to its short test period, low test cost, flexible test conditions, good controllability and high safety. . [0003] When carrying out a variety of bench tests (such as powertrain bench tests, gearbox bench tests, brake bench tests, etc.), it is often necessary to simulate the driv...

AI Technical Summary

Problems solved by technology

At this time, if the above inertia device is used, the purpose of changing the simulated inertia can only be achieved by equipping many metal disks with different thicknesses, and by replacing the combination of metal disks with different thicknesses, which will increase the cost of use and cause frequent disassembly. Make the test cycle longer
