The inertia load of straight line steering wheel 12 is loaded.
It is caused to be pushed up around counterweight bearing 3 due to counterweight 1, counterweight 29 and the spatial distribution of the mass of lever 6 and center of gravity
The inertia load parameter of stomidium can be calculated by formula (1),
Wherein, m, m1、m2、m3Respectively inertia load, lever 6, counterweight 1, the quality of counterweight 29, l, l1、l2、l3Point
Not Wei inertia load, lever 6, counterweight 1, counterweight 29 relative to the centroid position at the topped hole center of counterweight bearing 3, J, J1For
Inertia load, lever 6 relative to the topped hole center of counterweight bearing 3 inertia.Therefore, by designing lever 6, counterweight 1, counterweight
29 quality and fixed position, inertia, quality, the centroid position three of caused inertia load matching steering wheel can be caused to refer to
Mark.
Parameter determines after the completion of lever 6 designs, and is platform general part, but counterweight 1 and counterweight 29 consolidating on lever 6
Positioning is put and can adjusted with quality, therefore caused inertia load parameter can also be adjusted, i.e., by adjusting counterweight 1 and matching somebody with somebody
29 fixed position and quality size is weighed, inertia load inertia, quality, the centroid position of different straight line steering wheels 12 can be met
Three indexs, weighted platform is set to possess versatility, repeat usage is high, and different straight line steering wheels 12 only need to change counterweight one when testing
5 and counterweight 29, it is simple to operate.Because the parameter of fictitious load only has three (m, l, J), and counterweight 1 and counterweight 29
Customized parameter have four (m2, l2, m3, l3), therefore optional adjustment parameter is a lot, sees the mapping relations of formula (2).It is actual
In, so as to reduce the species of counterweight, it can further increase the versatility of platform taking human as the quality for determining counterweight 1.
F (m, l, J)~f (m2,l2,m3,l3) (2)
