Example Embodiment

[0045] Example 1

[0046] A preliminary test method for floor vibration comfort based on heart rate changes, such as figure 1 As shown, including the following steps:

[0047] S1: Obtain the standard value of the tester's heart rate on the floor of the standard vibration frequency, and the standard value of the heart rate is used to reflect the comfort level of the tester brought by the floor of the standard vibration frequency. The standard vibration frequency of the floor slab can be 3Hz, or 4Hz, 8Hz, 10Hz, 15Hz. In this embodiment, the standard vibration frequency of the floor slab is 3 Hz. The age of the tester is 18-50 years old, the weight of the tester is 45kg-70kg, and the height is 150cm-180cm. The specific steps are as follows:

[0048] Such as figure 2 As shown, design a floor slab with a critical value of natural frequency. The boundary condition is that the surroundings are just connected. A working condition X1 is set: ordinary people walk from point A to point B al...

Example Embodiment

[0058] Example 2

[0059] On the basis of embodiment 1, the standard value of the heart rate in step S1 may also be:

[0060]

[0061] among them, n is the total number of tests, in this embodiment, the value of n is 10, z ij It is the peak heart rate of the tester on the concrete floor at the step frequency i during the jth test, Y i Is the peak heart rate of the tester at step frequency i on the floor of the standard vibration frequency, for The absolute value of K i It is the standard value of heart rate at cadence i, and cadence i is i steps taken per unit time.

[0062] Obtaining the heart rate reference value in step S2 may also be:

[0063]

[0064] y i Is the peak heart rate of the tester at step frequency i on the floor to be tested, for The absolute value of k i It is the heart rate reference value at cadence i.

Abstract

The invention relates to the field of floor comfort testing, in particular to a floor vibration comfort preliminary testing method based on a heart rate change. The method comprises the steps of obtaining a heart rate standard value of a tester on a standard vibration frequency floor, wherein the heart rate standard value is used for reflecting the comfort level brought to the tester by the standard vibration frequency floor; obtaining a heart rate reference value of the tester on a to-be-tested floor, wherein the heart rate reference value is used for reflecting the comfort level brought to the tester by the to-be-tested floor; if the heart rate reference value is smaller than or equal to the heart rate standard value, determining that the comfort index of the to-be-detected floor is qualified, otherwise, determining that the comfort index of the to-be-detected floor is unqualified. The comfort level of the tester on the floor with the standard vibration frequency serves as a reference standard, the comfort level of the tester on the to-be-tested floor with an unknown vibration frequency is compared with a standard comfort level, whether the to-be-tested floor reaches the standardor not is judged, and the discomfort of residents due to the fact that substandard floors are adopted in a building is prevented.

Description

technical field [0001] The invention relates to the field of testing floor comfort, in particular to a preliminary testing method for floor vibration comfort based on heart rate changes. Background technique [0002] With the continuous improvement of engineering technology, the popularization and application of steel structures and the development of lightweight and high-strength materials, various new structural systems such as suspension structural systems and long-span structural systems have been widely used. Damping trend. [0003] Due to the complexity of structural systems such as suspended structural systems and long-span structural systems, the natural vibration frequency of the structure itself is low. When the frequency of pedestrian load excitation is similar to the natural vibration frequency of the floor, it will arouse a large vibration response of the floor, making people It resonates with the floor and affects people's normal life and production. Therefore...
