| Abstract: |
| This PaPer introduces two kinds of structural patterns and working principles of force determination device for outer load of strain types of farm implementing
hoeing and chiseling working parts in soil.“L一type for determination device”to determine force distance has three combination bridge ways:series resistance method;parallel
resistance method and matching K value method,of which series resistance method is
convenient to practical use. |
| Key words: farm machniery implement,force determination device,combination bridge way |
