(54) ДАТЧИК ДЛЯ ИЗМЕРЕНИЯ ДАВЛЕНИЯ ОДЕЖДЫ(54) SENSOR FOR MEASURING CLOTHING PRESSURE
Изобретение относитс к измерительной техннке , а нменно к устройствам дл исследований фнзико-механнческнх свойств текстнльных материалов н трикотажа.The invention relates to measurement technology, and, in particular, to devices for studying the fnico-mechanical properties of textiles and knitwear.
Известен датчнк давлени , содержашнй корпус и чувствительный элемент с наклеенными тензодатчикамн, прнчем корпус выполнен в виде чашки, в дне которой выфрезерОвана консоль Ij .-.A pressure sensor, a housing and a sensor with glued strain gauges are known, the housing is made in the form of a cup, at the bottom of which the console Ij .- is milled.
Недостатком устройства вл етс невозможность его использовани дл измерени динамического давлени одежды, особенно, прн испытани х ее в натуральных услови х, т.е. на теле человека.The drawback of the device is the impossibility of its use for measuring the dynamic pressure of clothes, especially when tested in natural conditions, i.e. on the human body.
Целью изобретени вл етс повышение точности измерени .The aim of the invention is to improve the measurement accuracy.
Это достигаетс за счет того, что в устройство введен демпфер, чувствительный элемент выполнен в виде диска с пазом на боковой поверхности, причем грани паза расположены параллельно торцам диска, а демпфер размещен в пазе диска.This is achieved due to the fact that a damper is inserted into the device, the sensing element is made in the form of a disk with a groove on the side surface, with the faces of the groove arranged parallel to the ends of the disk, and the damper is placed in the disk groove.
На фиг. t показано предлагаемое устройство , вид спереди; на фиг. 2 - то же, вид сверху, на фиг.З - принципиальна электрическа схема подключени датчика к усилительной и автоматической регистрирующей аппаратуре.FIG. t shows the proposed device, front view; in fig. 2 - the same, top view, in FIG. 3 - the electrical circuit of connecting the sensor to the amplifying and automatic recording equipment.
На корпусе датчика закреплено средство дл измерени давлени одежды. Корпус устройства выполнен в виде пластины I (см. фиг. 1) с ушками 2 и ремешка 3, служаш,его дл закреплени устройства на теле человека.A means for measuring the pressure of clothing is fixed on the sensor housing. The case of the device is made in the form of a plate I (see Fig. 1) with ears 2 and a strap 3, serving it, for fastening the device on the human body.
Средство дл измерени давлени одежды представл ет собой жестко смонтированный на пластине 1 диск 4 небольшой толщины с прорезью 5, грани которой параллельны торцам диска. На внешнем торце 6 диска 4 неподвижно установлены тензометрнческие преобразователи 7 и 8 (см. фиг, 1, 2, 3), из которых преобразователь 7 вл етс рабочим, а преобразователь 8 - компенсационным.Преобразователи собраны в полумостовую схему н электрически соединены с тензометрнческим усилителем 9 и шлейфовым осциллографом 10 (см. фиг. 3).The means for measuring the pressure of clothing is a disk 4 of small thickness rigidly mounted on a plate 1 with a slit 5 whose faces are parallel to the ends of the disk. At the outer end 6 of the disk 4, tension gauges 7 and 8 are fixedly mounted (see FIGS. 1, 2, 3), of which converter 7 is operational and converter 8 is compensatory. The converters are assembled in a half-bridge circuit and electrically connected to the strain gauge amplifier 9 and a loop oscilloscope 10 (see FIG. 3).
Средство дл измерени давлени одежды снабжено также демпфером 11, установленным в прорези 5 диска 4 (фиг. I). В качестве демпфера использованы резиновые пластины различной твердости, благодар чему можно регулировать амплитудно-частотную характеристику датчика.The means for measuring the pressure of clothing is also provided with a damper 11 installed in the slot 5 of the disk 4 (Fig. I). Rubber plates of various hardness were used as a damper, so that you can adjust the amplitude-frequency response of the sensor.
