Embodiment Construction

[0030] For convenience of understanding, the plurality of freedom terrain simulation apparatus will be described below, and these examples are intended to illustrate the scope of the invention.

[0031] In the description of the invention, it is to be described in the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "within", "outside", etc. The orientation or position of the indication is based on the orientation and positional relationship shown in the drawings, which is only for ease of describing the invention and simplified description, rather than indicating or implying that the device or component must have a specific orientation. Construct and operation, so it is not understood to be the limitation of the invention. Moreover, the term "first", "second", "third" is only used to describe purposes, and cannot be understood as an indication or implies relative importance.

[0032] In the description of the present invention, it is to be described in...

Abstract

The invention belongs to the technical field of performance detection equipment of vehicles or special engineering machinery, and particularly relates to a multi-degree-of-freedom terrain simulation device. The multi-degree-of-freedom terrain simulation device comprises a lower frame and at least two movement mechanisms arranged on the lower frame, wherein the movement mechanisms are used for bearing a tested engineering machine with walking mechanisms, the number and the positions of the movement mechanisms correspond to those of the independently-arranged walking mechanisms, and each movement mechanism comprises a fluctuation adjusting mechanism arranged on the lower frame, a steering mechanism arranged on the fluctuation adjusting mechanism and a walking supporting mechanism arranged onthe steering mechanism. The multi-degree-of-freedom terrain simulation device provided by the invention adopts a composite mechanism in which a plurality of three-degree-of-freedom motion platforms cooperatively move, can be used for providing support for various vehicle special engineering machinery, mainly completes walking, steering and operation simulation of the vehicle or the special engineering machinery on multiple parameters such as high and low terrains and rugged grounds, and provides a real working scene for vehicles or special engineering machinery.

Description

Technical field [0001] The present invention belongs to the performance testing equipment of vehicle or special construction machinery, and more particularly to a multi-freedom terrain simulation device. Background technique [0002] As a mechanical product, the vehicle will generate a dynamic load on the whole vehicle, subsystem, and key components in the case of normal use. In order to test the operation of the vehicle in real road conditions, the road analog device is designed. [0003] Current road analog devices can be divided into simulators active, car stationary or passive operation by power source; or car operation, actively adapt to different road conditions of different simulations. The first mode is unable to react the truth of the car, such as China Patent CN209802677U; the second is generally directly building a road condition, therefore requires a larger site, and can only be straightforward, and the vehicle turn is not possible to implement verification.
