The swing arm is fixed through the round pin hub connection with test platform. It is deciliter as an organic whole with measured piece and test bench swinging portion, through changing the pendulum length, measure the cycle separately, obtain the barycenter height and the inertia of measured piece through calculation, for the security of product, stability and ride performance provide accurate data and support.
Description
Technical field
This utility model belongs to agricultural equipment overall test apparatus field, relates to a kind of tractor rotary inertia and height of center of massTestTesting stand.
Background technology
Along with the fast development of mechanization of agriculture, tractor occupies very important status in farmland operation.In rural area, tractor is widely used for cultivated land and plows, and transports the means of agricultural production, but the accident therefore caused increasing the most more.Casualty accident is tumbled in the process of moving by tractor and is caused greatly, the complete machine rotary inertia of tractor and height of center of mass are to weigh the safety of tractor, stability and the important indicator of ride performance, and these parameters are even more important for narrow-track tractor.At present, domestic there is no be specifically designed for that tractor rotary inertia combines with height of center of mass test bed, thus develop the testing stand that a rotary inertia combines with height of center of mass measurement, be particularly important.
In long-term experiment work, the tractor rotary inertia that we develop and height of center of mass testing stand, principle according to physical pendulum, by changing pendulum length, successively record the hunting period under different pendulum length for twice, according to hunting period, it is calculated the overall distance for center of rotation to system center of mass point, and the rotary inertia that system is to center of rotation, try to achieve further by the rotary inertia of test specimen and height of center of mass, achieve satisfied effect.
Utility model content
The purpose of this utility model is to provide a kind of experimental provision that can accurately record tractor rotary inertia and height of center of mass.
The technical solution of the utility model is: tractor rotary inertia is test bed with height of center of mass, including: induction rod, bearing with spherical outside surface of usheing to seat, sensing timer, left support column, Lever Blocks, digital display obliquity sensor, test platform, swing arm, bearing pin, bearing with spherical outside surface, right support column；Left support column and right support column are bolted on ground, test platform passes on left bearing with spherical outside surface bolt of usheing to seat and is connected with left support column, right side is then rest directly upon on the arc surface of right support column by bearing with spherical outside surface, and bearing with spherical outside surface can move freely on the arc surface of right support column；Lever Blocks is connected respectively at swing arm and test platform by ear stud.Swing arm is connected fixing with test platform by bearing pin.
Being provided with sensing timer by bolt on left support column, swing arm is provided with induction rod, test platform is fixed with digital display obliquity sensor.
This utility model can obtain following beneficial effect after using technique scheme: is integrated with testing stand swing part by measured piece, by changing pendulum length, measure the respective cycle, by being calculated height of center of mass and the rotary inertia of measured piece, data supporting accurately is provided for the safety of product, stability and ride performance.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model tractor rotary inertia is test bed with height of center of mass.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.As it is shown in figure 1, tractor rotary inertia is test bed with height of center of mass, including: induction rod 1, bearing with spherical outside surface 2 of usheing to seat, sense timer 3, left support column 4, Lever Blocks 5, digital display obliquity sensor 6, test platform 7, swing arm 8, bearing pin 9, bearing with spherical outside surface 10, Right side support column 11.
Left support column 4 and right support column 11 are bolted on ground, test platform 7 passes on left bearing with spherical outside surface 2 bolt of usheing to seat and is connected with left support column 4, right side is rest directly upon on the arc surface of right support column 11 by bearing with spherical outside surface 10, and bearing with spherical outside surface 10 can move freely；Test platform 7 is regulated by Lever Blocks 5 with the distance of the centre of gyration, after distance has regulated, inserts the bearing pin 9 relative position with fixing swing arm 8 with test platform 7 in hole；In process of the test, the angle manually boosted directly reads from digital display obliquity sensor 6；Hunting period is measured with the time set that sensing timer 3 forms by induction rod 1.
In process of the test, first tractor to be measured is placed on experiment porch 7, make testing stand 7 table top under static state holding level, then testing stand is promoted, observe digital display obliquity sensor 6, when registration is let go close to 10 °, make testing stand do and freely swing, after some cycle timing, calculate T average period1, then with Lever Blocks 5 Adjustment Tests platform 7 apart from centre of gyration distance, after having adjusted, with bearing pin 9, swing arm 8 is fixed with testing stand 7, afterwards, repeats above step, again obtain T hunting period2.Then according to test bed height of center of mass known to self, rotary inertia, by calculating rotary inertia and the height of center of mass that i.e. can get measured piece；
Basis is the most test bed to be integrated measured piece with testing stand swing part, by changing pendulum length, measure the rotation period under different pendulum length, by being calculated height of center of mass and the rotary inertia of measured piece, data supporting accurately is provided for the safety of product, stability and ride performance.
