Abstract

The invention discloses a cab shaking measurement device and method. A gyroscope is used to measure the angular speeds of a cab in three rotating directions, a laser displacement sensor is adopted tomeasure the displacement of the cab in three translation directions, and a vibration acceleration sensor is adopted to measure the four angular vibration acceleration values of a cab bottom plate. Data normalization is performed on the three angular velocities and the three displacements, each physical value is scored, six physical quantities are weighted and multiplied to obtain a cab shaking intensity evaluation index, and a mean value and a variance of the vibration accelerations of the four points are calculated to serve as a cab shaking human body feeling evaluation index.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and relates to the measurement and evaluation of the cab shake of engineering vehicles, in particular to a cab shake measuring device, and also to a measuring method based on the measuring device. Background technique [0002] As important engineering construction equipment, construction machinery is widely used in road construction, mining and various engineering constructions, and its performance directly affects the speed and efficiency of engineering construction. With the continuous expansion of the driver group, their requirements for the working environment are also increasing. The driver's evaluation of the comfort of construction machinery directly affects the sales of the product. The acoustic and vibration comfort of the cab has become a new focus of attention in the industry. [0003] Due to the harsh road conditions and working environment of engineering vehicles, domes...
