Multiple-degree-of-freedom suspension K&C (kinematics & compliance) property test platform

Abstract

The invention discloses a multiple-degree-of-freedom suspension K&C (kinematics & compliance) property test platform, which mainly comprises a support system, a loading system, a measuring system, a movement platform system and a control system, wherein the support system is used for supporting a vehicle to be measured and the loading system, six electric cylinders in the loading system are used for driving the movement platform system to realize the six-degree-of-freedom movement, a left pier and a right pier in the loading system are slidingly connected above the movement platform system, a circular disc motor in the left pier and a circular disc motor in the right pier respectively drive a pier table to rotate, the measuring system is used for measuring the displacements and the applied forces of wheels of the vehicle to be measured, and the control system is used for collecting signals measured by the measuring system, and driving the loading system to load the vehicle to be measured. The multiple-degree-of-freedom suspension K&C property test platform has the advantages that the particular multiple-degree-of-freedom loading type is adopted, the lateral inclining angle and the longitudinal inclining angle of a real road surface can be completely simulated in the test process, the rotation inertia of the whole vehicle or component parts can be measured by little modification, the structure is simple, the measuring range is wide, and the application prospect is better.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension performance testing, in particular to a multi-degree-of-freedom suspension K&C characteristic test bench for measuring the K&C characteristic of automobile suspension. Background technique [0002] The suspension system is the core of the vehicle chassis, and its suspension kinematics and elastic kinematics characteristics (Kinematics&Compliance, hereinafter referred to as K&C characteristics) are directly related to the performance of the chassis and play an important role in the chassis development stage. Suspension kinematics characteristics (Kinematics, hereinafter referred to as K characteristics) describe the movement of the wheel during spring deformation and steering. change relationship. The elastic kinematics characteristic of the suspension (Compliance, hereinafter referred to as C characteristic) is the wheel alignment parameter caused by the force and moment between the...

AI Technical Summary

Problems solved by technology

The existing suspension K&C test benches all use the left and right piers with three degrees of freedom of movement and one degree of freedom of rotation to load the wheels. The structure is complex, the cost is high, and the distance between the left and right piers needs to be manually adjusted to suit different wheels. distance vehicles, and the adjustable range is small
