Embodiment 1

[0079] The following loading steps are for a seat using the 50th percentile H-point measuring instrument for loading. This embodiment measures the H point for a certain type of seat. During the loading process, the horizontal load required to maintain the H point measuring instrument is fixed, and the time interval for loading the load is constant. Therefore, in this embodiment, each application The horizontal load is a fixed value, the horizontal load loading time interval is the same, the friction coefficient between the H-point measuring instrument and the seat is set to 0.3, in terms of output settings: output a simulation animation file every 50 milliseconds, and output a simulation animation file every 10 milliseconds The contact force between the H-point measuring instrument and the seat outputs a three-dimensional coordinate value of the H-point every 5 milliseconds.

Abstract

The invention discloses a loading method for measuring H points of a seat simulation model and aims to overcome the problems that the seat H points can be measured only after seat trial-production and the H points cannot be measured accurately in the seat simulation model. The method comprises the steps of (1) loading of own gravity, (2) applying of a horizontal load, (3) applying of a thigh load, (4) second-time applying of the thigh load, (5) applying of a load for hips and a trunk, (6) third-time applying of the horizontal load, (7) applying of a chest load, (8) fourth-time applying of the horizontal load and (9) extraction of the seat H point data. During the loading of the own gravity, an H point measurement instrument equipped with shank balance weights only is loaded in the gravity direction, the H point measurement instrument can then stably fall onto the seat model under the gravity effect, and a loading time interval is 0-1.2 s. During the applying of the horizontal load, the horizontal load of 56-76 N is applied at a horizontal load position (24) of the H point measurement instrument on the lower position along the direction of a T-shaped frame (13). During the applying of the thigh load, the load is applied on two thigh balance weight bases (8), and a time interval is 0.3-1.2 s.

Description

technical field [0001] The present invention relates to a kind of loading method, more precisely, the present invention relates to a kind of loading method for measuring the H point of seat simulation model Background technique [0002] Point H is the reference point for car design, and point R is the reference point for seat design. In theory, point R and point H are coincident, but it is difficult to achieve coincidence in practice. The H point refers to the connection point between the thigh and the torso of the human body in the 2D human model or the 3D human body model, also known as the Hip Point, which is the hip joint in the human body model. On the H-point measurement device, it is reflected as the center line of the axis connecting the thigh and the torso. Considering the measurement error, it is actually composed of a series of points. The H point is a parallelogram range of motion, because the front seats generally It is adjustable, and the H point can usually b...
