Abstract
The invention relates to a spoke type force measuring wheel pair based on a sensor, which comprises a force measuring wheel, a connecting shaft, a sensor and a clamping device, wherein the force measuring wheel has a uniform thickness spoke type structure which can improve the measuring sensitivity. The invention overcomes the shortcomings of the surface pasted strain gage caused by the traditional force measuring wheel pair, only requiring to tightly clamp the sensor on the force measuring wheel spoke through the clamping device after being processed in a precise workshop. The vertical and lateral forces loaded by the force measuring wheel can be dynamically measured at real time through a pressure method and a shearing force method. The force measuring wheel pair of the invention is convenient to assemble and disassemble, is easy to maintain and exchange, greatly increases the measuring precision, and avoids the known shortcomings that the force measuring wheel pair is difficult to manufacture, difficult to maintain and repair and is expensive to manufacture.
Description
Technical field
It is right to the present invention relates to a kind of sensor-based spoke type dynamometry wheel.
Background technology
The research of dynamic wheel track power effect is the important evidence of appropriate design rolling stock and track structure parts between rolling stock and the track, wheel track power can make rolling stock safe operation in orbit, also may cause unsound vehicle derailing, wheel severe wear and unsteadiness of wheels etc.For the further interaction force relation of grasping between the wheel track, the expert has done big quantity research both at home and abroad, and wherein utilizing the dynamometry wheel is a kind of direct, failure-free method to carrying out real time dynamic measurement wheel track power.
The dynamometry wheel that is used at present testing is to being divided into axonometry and wheel survey method, and axonometry is to paste strain-gauge in certain sensitizing range on the adapter shaft and form vertical force and the transverse force that the test bridge circuit acts between to wheel track by certain method of attachment and measure.Wheel survey method is to paste strain-gauge on to disc and form vertical force and the transverse force that the test bridge circuit acts between to wheel track by certain method of attachment and measure at wheel.Be not difficult to find out, no matter be that any dynamometry wheel is to paste strain-gauge group bridge method to what all adopt at present, this kind method requires to paste the strain-gauge position and angle must be very accurate, and owing to a dynamometry wheel is made up of many strain-gaugies bridge circuit, if existing deviation or be damaged, some strain-gauge paste positions all can have influence on whole test bridge circuit, even the respective strain sheet may cause right unavailable of whole dynamometry wheel after damaging, therefore this dynamometry wheel that makes is bigger to difficulty on the manufacture craft, later maintenance is difficulty, and making and maintenance cost are higher.Because known dynamometry wheel utilizes pressure application and moment Method respectively to transverse force and vertical force measurement, measuring accuracy is not high.
The inventor is according to the experience of being engaged in sensor research aspect for many years, for solving known dynamometry wheel to existing defective, makes the change of essence from structure and test philosophy, and it is right finally to have invented a kind of sensor-based spoke type dynamometry wheel.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming known dynamometry wheel to existing defective, the present invention makes the change of essence from structure and test philosophy, provide a kind of make simple, easy to maintenance, save cost, sensor-based spoke type dynamometry wheel that measuring accuracy is high is right.
For this reason, sensor-based spoke type dynamometry wheel that the present invention proposes is to partly being made up of dynamometry wheel, adapter shaft, sensor, fixing device etc., need not strain-gauge to be pasted on the surface at the dynamometry wheel, utilizing fixing device that sensor is anchored on the dynamometry wheel spoke gets final product, it is convenient to install, dismantle, for ease of maintenaince with replacing.
Characteristics of the present invention and advantage are:
The spoke type dynamometry wheel that the present invention is based on sensor to need not wheel on paste strain-gauge, utilize fixing device will be anchored at the high-precision sensor that precision workshop processes on the dynamometry wheel spoke, utilize pressure application and shearing method respectively vertical force and transverse force to be measured, improved the right survey precision of dynamometry wheel greatly.In the use, be damaged as some sensors and can unclamp fixing device, change a new sensor and get final product, maintenance and repair is convenient; Wheel abrasion exceed limit value and can not continue to use as dynamometry, the dynamometry wheel can be gone up all the sensors and pull down, and be installed on the dynamometry wheel spoke of remanufacturing and get final product, and can obviously save financial cost and fabrication cycle.
