(OP)
I am working on analysis of front part(rear part excluded) of car in optimumk
in case of pure heave what is the axis of rotation?
is it whether axis passing through centre of car or centre of front wheel axis?

RE: optimumk help
also in the analysis wheels are not leaving the ground why is it so?

You can't get meaningful answers to such a vague question. As you can see, only some of us are mind readers.

RE: optimumk help
If you want an independent suspension design that doesn't cause this and doesn't cause camber change with suspension travel, have a look at the double-trailing-arm suspension of the original air-cooled VW Beetle. If you copy that suspension design, perhaps you can achieve ride and handling characteristics not too different from a 1960's (designed 1930's) air-cooled Beetle. Is that what you are looking for?
Or perhaps you could switch to a solid axle leaf spring front suspension, since with those, even if the instant-center is quite high off the ground, the front wheels will remain the same distance apart and always perpendicular to the ground and always parallel to each other, no matter the bodyshell movement. Do you want to achieve the ride and handling characteristics of a '56 Ford F100?
Sometimes it's too easy to get hung up on something that "seems bad" even though in the grand scheme of things, it doesn't matter.
You need to explain what it is that you are trying to do and perhaps a little of WHY you are trying to do that. Double-wishbone suspension designs are extremely common and widely used. Depending on how you set them up, the ride and handling can be anywhere between '53 Buick and 2009 Formula 1 car.
