Problems solved by technology

The evaluation of ride comfort is mostly based on the subjective evaluation of the car man-machine design data, and it is impossible to convert the customer's subjective ride feeling into an effective, scientific, convincing quantitative index with clear causal relationship

Embodiment Construction

[0025] The patent will be described in detail below in conjunction with the flow chart.

[0026] A method for evaluating the ride comfort of a commercial vehicle based on electromyographic measurement, comprising the following steps:

[0027] Step 1. Select several commercial vehicle drivers as experimental subjects. At the same time, the main force-generating muscles of the upper and lower extremities of the body during the process of getting on and off the bus were selected as candidate test muscle groups, and the activation state of the candidate test muscle groups was measured and analyzed by a multi-channel physiological recorder electromyographic test system.

[0028] The main function of the upper limbs of the driver when getting on and off the car is to drag the body and help the body to get on the car stably. In order to evaluate whether the position of the vehicle armrest is appropriate, select the left upper trapezius muscle, left middle deltoid muscle, left upper s...

Abstract

The invention discloses a commercial vehicle ride comfort assessment method based on electromyography measurement. The commercial vehicle ride comfort assessment method comprises the following steps: selecting main power-generating muscle of the upper and lower limbs of the bodies (in the getting on or off process) of tested persons as the candidate measurement muscle groups, and measuring the activation state of each piece of tested muscle of the candidate measurement muscle group of each tested person by adopting an electromyography measurement system of a multichannel physiological recorder; counting the activation degree of each piece of tested muscle of each tested person, thus obtaining the muscle activation degree average value of each piece of tested muscle; selecting the main muscle group of each tested person according to the muscle activation degree average value of each piece of tested muscle; setting the weight of the selected main muscle group; and determining the commercial vehicle ride comfort assessment function according to the weight. The method is convenient to operate, can quantify the index of the ride performance of the commercial vehicle, is low in cost, and is high in efficiency.

Description

technical field [0001] The invention relates to a vehicle comfort evaluation method, in particular to a commercial vehicle ride comfort evaluation method. Background technique [0002] With the improvement of people's living standards at this stage, the comfort of cars has become an indicator for evaluating cars. Similarly, comfort is also what the public needs for commercial vehicles. Or the convenience and comfort when leaving the cab of a commercial vehicle. For now, there is no complete set of accurate and effective objective evaluation system for the rideability of commercial vehicles. For commercial vehicles, the general comfort evaluation system only includes seat comfort and steering wheel handling comfort. and other definitions, and these definitions are all definitions for the comfort in the cab. Since the cab of a commercial vehicle is higher than the cab of a general car, it is necessary to include the comfort when entering and leaving the cab into the overall ...
